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.

Consider the two statements:
Statement I: If the duration of a cardiac cycle is 0.8 seconds, the number of heart beats heard through a stethoscope and the number of cardiac cycles per minute will be 75.
Statement II: Neural signals through the sympathetic nerves can increase the rate of heart beat, the strength of ventricular contraction and thereby the cardiac output.
1. Statement I is correct; Statement II is incorrect
2. Statement I is incorrect; Statement II is incorrect
3. Statement I is correct; Statement II is correct
4. Statement I is incorrect; Statement II is correct

A specialised nodal tissue embedded in the lower corner of the right atrium, close to Atrio-ventricular septum, delays the spreading of impulses to heart apex for about 0.1 sec. This delay allows:
1. blood to enter aorta.
2. the ventricles to empty completely.
3. blood to enter pulmonary arteries.
4. the atria to empty completely.
