Consider the given two statements:
| Assertion (A): | SA node acts as the normal pacemaker of the human heart. |
| Reason (R): | SA node is located in the wall of the right atrium. |
| 1. | (A) is True but (R) is False |
| 2. | Both (A) and (R) are True and (R) correctly explains (A) |
| 3. | Both (A) and (R) are True but (R) does not correctly explain (A) |

| 1. | Heart failure | The state of heart when it is not pumping blood effectively enough to meet the needs of the body. |
| 2. | Heart attack | The heart muscle is suddenly damaged by an inadequate blood supply. |
| 3. | Angina pectoris | Acute chest pain when excess oxygen is reaching the heart muscle due to vasodilation. |
| 4. | Cardiac arrest | The heart abruptly stops beating. |
| 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. |
