Lets say I have an ECG signal and I want to separate it 4 second segments. How to do it in MATLAB?
% MATLAB Code
load ('C:\Users\Explorer\Documents\MATLAB\PhysioNet_Database\Malignant_Ventricular_Ectopy_Database\418m.mat');
signal=val(1,:);
plot(signal)
xlabel('Time')
ylabel('Voltage')

If you have the signal processing toolbox, see buffer(), provided the signals are equally spaced in time.

The Physionet EKGs are all sampled at constant time intervals, but the intervals are different in different records. The sampling frequencies and other data for each record are all available in the database.
