I have a .dat file and a .hea file which contains all 12 ecg leads.
i want to visualize each ecg lead in a different figure
I use the following code to store .dat data to a variable
fp= fopen('00001_lr.dat','rb');
ecg=fread(fp,'short');
frequency is 100hz and length is 10 secs and contain 12 leads (V1 to V6, I, II, III, aVR, aVL, and aVF )
thanks and regards.

Hi, I have the same error when trying to read a local .dat file.
This is my matlab directory, my .dat file is located in F:\Open ECG file data.
Could you please help me solve this problem?

I auggest that you post this as a new Question, and include a lot more detail, specifically uploading the ‘.dat’ file as an attachment.

This is the standard format for EKG record display:
EKGD = load('temp.mat');
EKG = EKGD.signal;
Leadc = {'I','II','III','aV_R','aV_L','aV_F','V_1','V_2','V_3','V_4','V_5','V_6'};
figure
kc = 1;
for k1 = 1:4
for k2 = 1:4:9
sbpt = (k1-1)+k2;
subplot(3,4,sbpt)
plot(EKG(1:300,kc))
title(Leadc{kc})
grid
ylim([-1 1])
kc = kc+1;
end
end
producing:
Characteristically, only three cycles are displayed, except for the separate Lead II rhythm strip (not shown here, would be a separate plot).
Diagnosis: Abnormal EKG, with pronounced left-axis deviation,with an axis of about -45°. Impression: Consistent with left bundle-branch block.
