With the help of ECG tracings, the heart rate of the person can be calculated by:
| 1. | measuring the size of the PR or PQ interval |
| 2. | counting the number of QRS complexes in a given period of time |
| 3. | counting the number of T waves between two successive QRS complexes |
| 4. | measuring the size of the QRS complexes |
