Heart Rate

Hi all,
I am working on an ECG project for my thesis . I have implemented the hardware and I am acquiring the ecg signal through serial port . I did that all and i am having a signal that is displayed . now i need to go further with the project and add some heart rate indicator to it .
I need a sample VI that i connect the ECG signal to, and then extract the heart rate from it .
can you guys help me with this ?
Regards .
Bill David

Dear friend ,
thank you for the very fast reply .
yes i have digitized the signal using the microcontroller PIC ( 16F874) from microship .so i am sending diitized values to the serial port .
well . talking about the biomedical toolkit and DAQ , I am not using them at all . and this is the challenge . to get a real ECG signal through serial port .
I am having real ECG signal that is displayed yet . but wanna do further .
can you suggest anything ?
thank you .

Need to get the heart rate in run keeper without bying expense additional hardware

Hi,
I am using runkeeper to track my activities.
Till now, there is no compatible bluetooth device that can work directly with the iPhone in order to get the heart rate, this is very dispapointing.
Any project in progress on this point?

Nope, that didn't help. now the dmesg related lines appear as:

TuxOnIce: Can't translate "/dev/disk/by-uuid/4564e7cd-aa5b-4b41-a7b5-20db4069bf1b" into a device id yet.
Also, that 6GB swap partition you got is a pure waste or resources. You need 3GB of swap max, and that is only if you want to store all your cache when you hibernate. If not, you don't even need a swap. If you're a normal user (means, you're not using some resource heavy apps, like those for editing HD vids or similar).
Sadly I realized that quite late Can't do a thing about it now.

Pairing my headphones and heart rate monitor at the same time

I want to know if I will be able to use my Jaybird Bluetooth headset and my Runtastic heart rate monitor at the same time?

It shouldn't be a problem. I do it with various BT headsets and a Wahoo HR monitor. You can have multiple BT devices connected to an iPhone at the same time as long as they aren't the same type of device (two speakers, two HR monitors).

Heart Rate Monitor compatibility

is the Polar Monitor: http://www.polar.fi/us-en/products/accessories/PolarWearLink_transmitterNike
compatible with any nike+ configuration? I'm using a second generation nano with the nike plus dongle and sensor.

The Polar Wearlink+ Nike+ heart monitor is only compatible with the 5th generation iPod nano.
If you want to track heart rate on an iPhone or iPod touch, there is a company that developed a dongle that ( like the popular Nike+system ) creates a wireless bridge.
Digifit uses a different technology called ANT+ and it is interoperable with > 80 sensors currently being sold by big brands like Garmin, Adidas, Spinning® and other leaders in the industry.

Probably a stupid question on heart rate sensor

Can i use the Nike (or better the Polar Wearlink) heart rate sensor together with the Nike+ shoe sensor ? Can the ipod peering with two bluetooth sender ?
Please do'nt hit me, about that stupid question ..

According to the Polar web site it is only compatible with the 5th generation iPod:

What heart rate monitors will pair with the new iPod nano?

Are there heart rate monitors that will pair with the new 7th generation iPod nano?

It's supposed to support "Bluetooth Smart" HR monitors.

How do you input/upload the templates for Heart Rates, EKG, etc. onto an already existing form of LabView?

I have LabView 9.0 and I remember last year when I got it I had to go through several steps in order to upload the templates for Heart Rate, EKG, and Blood Pressure. However, since then, several of my computers have been worked on within the district and the templates are no longer on the main page anymore and I have forgotten the steps to completete to get them back. Can anyone help me??!!

What main page are you referring to? Are you referring to the Getting Started window that has the "VI from Template..." link that pulls up a dialog to select the type of file to create? That has a tree node that you can navigate and there's a VI -> From Template -> User node. If you place the template in the <labview>/templates folder then they will show up in this node.

How do you determine the distance between the QRS interval, as well as the time over that distance, in order to calculate a heart rate

Hi!
I have a continuous sample data acquistion VI created. I collected an ECG signal from electrodes connected to an ELVIS unit. Once I viewed my signal, I am curious to determine the heart rate. I need to know how I can find the R-R interval, as well as the time over than span, so I can roughly determine the heart rate, continuously. Each time a new ECG wave occurs, the heart rate should be modified automatically. Some algorithm is required.
Thanks!

Hello bmeecg,
Welcome to the NI forums! If I understand your question correctly, you wish to calculate the instantaneous heart rate from your ECG (the inverse of your R-R interval). I would recommend using the Peak Detection vi (Functions Palette»Signal Processing»Signal Operation) to determine the location of the R wave (since it is the largest magnitude, you could set a threshold above your P and T waves so that it only picks up the R wave). The calculation for time is in the detailed help for the Peak Detection vi (Ctrl+H»Hover over the VI»Detailed Help).
I also found this forum which has a VI that reads an ECG and then does a lot of analysis. Maybe this would help you out as well.
And just FYI, the Counter/Timer forum is oriented toward our counter/timer boards (e.g. the PCI-6602), the Multifunction DAQ forum probably would have more of the type of people that could help with this issue.
However, please post back here if you have more questions about this.

How do I count and display events every few seconds and then convert the counted values into events per minute? (for a heart rate monitor)

Hi everyone,
I'm building a heart rate monitor as a final year project with my lab partner using the NI USB-6009 and Labview 2009. We have managed to obtain a signal using a photo transciever, smooth it out and count the events, however the count is incremental.
We wish to count the number of pulses we obtain for a few seconds (5-10 for example) and then use this value to obtain a pulse rate in beats per minute (e.g. 10 pulses in the first 10 seconds would give an estimated BPM of 60 etc etc).
Does anybody have ides on how we could implement this? We have tried timed loops, elapsed time VI's and other things but nothing gives us what we need.
Thanks in advance for any help that is offered.
Jeshua Graham.

We are very new to Labview. We are taking a raw signal from our DAQ and then using VIs to filter and then trigger counts on rising edges. I have attached our vi file to this post for you to look at (I hope that is what you mean by code).

Watch keep failing heart rate detection

Does anyone has problem with the heart rate monitor?
I have normal skin color (light, no tattoos) and the heart rate monitor can't find my pulse. The last correct one it detected was 24 hours ago. It's been failing for more than 10 times in a row and still can't get my heart rate. I had the watch for 3 days.

Howdy huynh van du,
Welcome to Apple Support Communities.
Congratulations on your new Apple Watch purchase!
From what I gather, the heart rate sensor isn’t able to measure your heart rate.
The article linked below provides a lot of great information about how the Apple Watch measures your heart rate and it also has troubleshooting tips that’ll resolve most issues related to getting that measurement.

IOS8 8.0.2 Bluetooth will not connect to Heart rate Monitor H7

I have just switched over to the iPhone 6 and it is running the 8.0.2 IOS 8 version but it will not pick up or pair with my Heart rate Monitor. We saw the same issue when Updating to 8.0.2 on the iPhone 5. It looks like when you update to the new IOS it will break the Bluetooth connecting option to the drive that worked on IOS 7 or before.
I thought this would be an issue with the HR monitor but it works fine on any device until yu update to IOS 8. I would say this is a backwards compatibility issue with IOS 8 not connecting to devices that iPhone used to connect to in Earlier IOS versions.
Are there any plans to fix this bug in IOS 8 to allow for being able to use Devices that worked in previous IOS versions?

If you don't already have a current backup, back up all data, then reinstall the OS.* You don't need to erase the startup volume, and you won't need the backup unless something goes wrong. If the system was upgraded from an older version of OS X, you may need the Apple ID and password you used.
If you use FileVault 2, then before running the Installer you must launch Disk Utility and select the icon of the FileVault startup volume ("Macintosh HD," unless you gave it a different name.) It will be nested below another icon with the same name. Click the Unlock button in the toolbar and enter your login password when prompted. Then quit Disk Utility to be returned to the main Recovery screen.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
If you installed the Java runtime distributed by Apple and still need it, you'll have to reinstall it. The same goes for Xcode. All other data will be preserved.
*The linked support article refers to OS X 10.10 ("Yosemite"), but the procedure is the same for OS X 10.7 ("Lion") and later.

Help connecting to external heart rate monitor

From all I've read, chest strap heart rate monitors seem to be more accurate. So I will continue to use my wahoo tickr for my gym workouts. I followed the instructions to pair my watch to the tickR from the settings menu under Bluetooth but it just continues to search and never finds it. Has anyone had any luck doing this?

Make sure you HRM isn't connected to anything else, like the app in your phone. When I closed the wahoo app down, then the watch was able to connect. So, it can only be connected to one device at a time.

Bluetooth keeps disconnecting with heart rate sensor

Hi,
I recently bought one of the Bluetooth LE Heart Rate Sensor. It is a brand called "MEDISANA" that you can get in Germans market Lidl.
I tried to pair it in several sports applications like Endomondo, Adidas Micoach etc and they all fails. In Endomondo sensor is keep connecting and disconnecting....
I've also tried to pair same sensor on my mate Z2 running KitKat 4.4.4 but end up with same results.
Yesterday I loaded official Lollipop 5.0.2 to my Z3C but nothing change to my surprise....
The funny thing is that same Heart Rate Sensors works fine on my wife cheep Nokia Lumia 520 and also on one of my colleagues android 4.4.2 (dont remember the brand).
So it looks like the issue is only related to Sony's mobile.
Does anyone has faced same kind of issues with BTLE sensors?

Sorry but why is every little thing that goes wrong or isn't supported due to compatibility always Sony's fault - It's never the manufacturer or developers fault - Like i said contact the manufacturer and if they say it's compatible then ask for a statement saying so.

Slow running data for heart rate variability VI Please help my thesis is due in 3days!! :(

Hi there i'm having a great issue with a VI i have created to detect heart rate variabilty from ECG and PPG signals and seeing which one is most accurate with regards to HRV.
I initially recorded 25 minutes worth of data and saved this into a text file. which has 2 columns the 1st being PPG data the 2nd ECG. There are at least 1000000 rows of data
I am now running this data into a VI which should give me results such a RMSDD PNN50, poincare plots and histograms etc the trouble i'm having is the VI is initially starts of fast then becomes incredibly slow i left it running for over 10hours and it hardly read any data
and me not being such a big labview expert knows how to fix this. I would be most grateful if somone could help me find my error as my thesis is due in 3 days and i'm stuck on this last part. I have attached my VI below . please please help me!

First question: does the code produce the correct result, just slowly?
So you have a million data points and process them one point at a time in a FOR loop, updating several xy graphs and charts and building arrays. Most indicators will get overwritten with each iteration.
You are heavily filtering the data (twice!) and take the derivative (twice=second derivative). You are doing a pt-by-pt peak finding on 50 points with every new point added, meaning that you mostly analyze the same data (differing by only one point with each iteration. Seems inefficient. Wouldn't you detect most peaks 50x?
Since your data is filtered, maybe it would be sufficient to decimate the data before the loop processing. How correlated are adjacent points?
Have you analyzed which part of the code is slowest? What is the current execution time ("slow" is subjective) and what speed would you like to have instead?
Things like the histogram only needs to be done exactly once at the end. It seems pointless to do it over and over, a million times in a row even if the data did not change. Same problem for all the graphs.
You seems to take the difference between adjacent points in the generated array. Again you are repeating the same calculation over and over. Wouldn't it be much more effiicent to keep the array of pairwise differences in the shift register and use a scalar shift register to retain the immediately previous point. Subtract the new point from the previous and add it to the array instead.

Is there a way to track calories of a workout with heart rate monitor?

I got a polar heart monitor and like how it tracks my HR during runs. However, I am wondering if there's a way to track my calories burnt doing something like circuit training.

It's just common sense to me. Someone who is in great shape will be burning X calories at a certain heart rate, doing whatever amount of physical activity. Someone who is in poor shape will have a certain heart rate, while doing less physical activity, and therefore burning fewer calories. The simple device cannot know you (as an individual) at such a deep level, to base an estimate on calories using just your heart ratee
My iPod just asks for my weight and height, and uses that as the basis for estimating calories burned. I could be a fat couch potato or an NFL pro linebacker. That is not enough information to calculate an accurate calories number, based on heart rate alone. There has to be a component in the exercise that counts predictable and consistent physical movement. Taking a step while running or walking IS something the device can count, and provide a reasonably accurate calories number.
Then why is this heart rate monitor able to be used to calculate calories if I buy a watch which syncs with it?
I think you answered your own question. It can do it IF you buy the watch device, but not without the watch device. The heart rate monitor can provide a calories estimate IF the watch device provides it with something that it is counting during the exercise. For example, if the watch has GPS, it can provide the distance you traveled.

Can iWatch display heart rate as a percentage of max?

Can the iWatch display heart rate readings not as "beats per minute" but as a percentage of the maximum heart rate of the wearer?

danielfromrandolph wrote:
You would have to input a lot of personal information as Max heartbeat is based on several factors, Including Age, weight and health factors, and I do not think it would be pratical for them to update this
They could simply allow you, like so many other programs do, to input your Max heart rate already calculated based on whichever formula you chose. Then all the program would need to do would be to display heart rate as a percent of that number. However, I suspect that calculation of a Max heart rate based on one of the commonly used formulae would be a trivial matter. I have far less smart smart watches that can do it.
