Hello,
Refer to below link

If you have Database with high concurency some blocking is inevitable ,moreover if blocking is there for few seconds its not an issue a long block is a issue though.Below query will give blocking information
select * from sys.sysprocesses where blocked <> 0
To check lead blocker
IF EXISTS ( SELECT 1 FROM master.dbo.sysprocesses WHERE blocked <> 0 )
SELECT spid,
status,
loginame = SUBSTRING(loginame, 1, 30),
hostname = SUBSTRING(hostname, 1, 12),
blk = CONVERT(char(4), blocked),
open_tran,
dbname = SUBSTRING(DB_NAME(dbid),1,10),
cmd,
waittype,
waittime,
last_batch
FROM master.dbo.sysprocesses NOLOCK
WHERE spid IN (SELECT blocked FROM master.dbo.sysprocesses)
AND blocked = 0
ELSE
SELECT 'No blocking found!'
