| Q. |
A typical ECG wave is |
| A. | Periodic |
| B. | A-periodic |
| C. | Quasi – Periodic |
| D. | Non – Periodic |
| Answer» C. Quasi – Periodic | |
| Explanation: ECG wave comprises PQRSTU segments. In this, P, R, T, U are all waves that go above the baseline and Q, S are waves that go below. However, P wave and R wave are not periodic. Periodicity is checked between the successive R waves. Quasi periodic waves are those which are periodic in a certain interval. Since the ECG signal is periodic in R to R interval or P to P interval, its a Quasi periodic wave. | |
