What would not be correct for the recordings seen on an ECG?
1. The P-wave represents the electrical excitation of the atria, which leads to the contraction of both the atria.
2. The ventricular contraction starts shortly after S wave and marks the beginning of the systole.
3. The end of the T-wave marks the end of systole.
4. Since the ECGs obtained from different individuals have roughly the same shape for a given lead configuration, any deviation from this shape indicates a possible abnormality or disease.
