Find H1 style in Top of Frame only

Question

Hi Everyone,
Request:
I want to find "H1" style in top of frame only. It is two column book.
If "H1" style comes in both the columns 1 and 2.
Problem:
Document using span columns, so the script will find all the  H1 style falls in first line of every column.
Trying script in  ways:
var myDoc = app.activeDocument
app.activeDocument.viewPreferences.horizontalMeasurementUnits = app.activeDocument.viewPreferences.verticalMeasurementUnits = MeasurementUnits.MILLIMETERS;
var myTextFrame = myDoc.textFrames.everyItem().getElements()
for(i=0; i<myTextFrame.length; i++)
        if(parseInt(myTextFrame[i].geometricBounds[3] - myTextFrame[i].geometricBounds[1]) == 180)
    for(j=0; j<myTextFrame[i].textColumns.length; j++)
        if(myTextFrame[i].textColumns[j].lines[0].appliedParagraphStyle.name == "H1")
            alert("H1 in First line of Frame\n"+ "Contents:" + myTextFrame[i].textColumns[j].lines[0].contents + "Page number: " + myTextFrame[i].textColumns[j].lines[0].parentTextFrames[0].parentPage.name)
            app.select(myTextFrame[i].textColumns[j].lines[0].parentTextFrames[0])
            exit(0)
Could anyone please give solution.
Kindly check the screenshot
Thanks in advance

Hi,
A solution could be to compare .endBaseline properties.
i.e.:
myTextFrame[i].textColumns[0].lines[0].endBaseline ==> this could be a base for textFrame [i]
so make the next if startement with two conditions:
- proper paraStyle
- proper endBaseline of 1st line of x textColumn (equal or "no higher then...")
