Plot 12-leads ECG signal in one figure

Hello,

How to plot 12-leads ECG signal in one figure?

The ECG data are included in the structure:

% Create a structure to hold the ECG data

N = size(rawData,1)

ecgData = struct();

ecg = struct();

% Therefore

ecgData.leadI=rawData(:,2);

ecgData.leadII=rawData(:,3);

% The augmented vector leads and lead III are derived as

% III=II-I; aVR=-(I+II)/2; aVL=I-II/2; aVF=II-I/2

ecgData.leadIII=ecgData.leadII-ecgData.leadI;

ecgData.aVR=-(ecgData.leadI+ecgData.leadII)/2;

ecgData.aVL=ecgData.leadII/2;

ecgData.aVF=ecgData.leadII-ecgData.leadI/2;

ecgData.V1 = rawData(:,8);

ecgData.V2 = rawData(:,4);

ecgData.V3 = rawData(:,5);

ecgData.V4 = rawData(:,6);

ecgData.V5 = rawData(:,7);

ecgData.V6 = rawData(:,1);

You can use the tiledlayout function.

To use the commonly-accepted plot format for a 12-lead EKG —

EKG = rand(12, 30)

EKG = 12×30
