It is a positive wave occurring after the T-wave. Its amplitude is generally one-fourth of the T-wave’s amplitude. The U-wave is most frequently seen in leads V2–V4. Individuals with prominent T-waves, as well as those with slow heart rates, display U-waves more often. The genesis...

The heartbeat is recorded on an electro- cardiogram (ECG) as a characteristic trace determined by changes in the electrical activity of the heart muscle. The T wave is a component of this waveform that is associated with the repolarization phase of the action potentials. It is asymmetrical in...
It also causes a deflection of the ECG needle, giving rise to the ‘T’ wave. After the T wave it is sometimes possible to see an additional ‘U’ wave, which, if present, is not thought to be very clinically important. The gap between the ‘S’ and ‘T’ waves, called the ‘ST...

After creating your mock ECG, analyse it to the best of your ability. Can you see a P Wave? Were you able to make the marble move enough to create obvious QRS waves? Is there a T Wave in your model? Repeat the process until you are able to create a clear ECG pattern with ...
To detect the P wave, you can search for the local maximum before the R peak. For the T wave, look for the local maximum after the R peak. Here is a simplified example of Matlab code to detect the P, Q, R, S, T points on an ECG waveform: ...
