how to find peaks like P,Q,R,S and T detection of ecg signal for my data that i acquired for a period of 10 minutes(60​0000sample​s)through BIOPAC SYSTEMS MP45 with a sampling frequency of 1000hz?can anyone suggest me the code for my data

I'm having ECG signal for a period of 10 minutes duration i.e.,600000 samples that i acquired through the BIOPAC MP45 systems with the sampling frequency of 1000 hz. i'm in need to find the peaks of the ECG signal. eventhough so many codes are there i couldn't get the peak detection for my data that i enclosed here. so i request you people to suggest me the code to find peak detection for my data as soon as possible.

sounds like you should be doing some frequency analysis to isolate the heartbeats... then processing them separately...
as an ad-hoc way of getting the peaks.... you might try:
[~,~,raw ] = xlsread('10mins dataecg\haarikaresp10.xlsx');
a = cell2mat(raw);
localmaxind = 1;
localmaxs = [];
counter = 1;
for i =2:length(a)
if a(i)>a(localmaxind)
localmaxind = i;
localmaxs(counter) = i;
end
if a(i)<=0 && a(i-1)>0
counter= counter+1;
localmaxind = i;
end
end
plot(a)
hold on
plot(localmaxs,a(localmaxs),'ro')
