Inadequate supply of oxygen to heart muscles leads to a symptom of acute chest pain. This disorder of the circulatory system is identified as:
| 1. | Angina pectoris | 2. | Cardiac arrest |
| 3. | Heart failure | 4. | Coronary Heart Disease |
| 1. | Normal level |
| 2. | More than normal level |
| 3. | Less than normal level |
| 4. | Very less than normal level |
| 1. | No antigens - A & B is present |
| 2. | Only antigen - A is present |
| 3. | Antigen - B is present |
| 4. | Both antigens - A & B are present |
| 1. | Serum albumins | 2. | Fibrinogen in plasma |
| 3. | Serum globulins | 4. | Triglycerides |

| A. | P-wave | I. | Ventricular repolarization-relaxation phase |
| B. | P-R interval | II. | The onset of ventricular depolarization - leads to ventricular contraction |
| C. | QRS complex | III. | Time for the impulse to be conducted from SA node to the ventricles through the AV node |
| D. | T-wave | IV. | Atrial depolarization - leads to atrial contraction |
