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. |

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. |
