INSTRUMENTAL METHODS

1. Determine a voltage of waves and rhythm of cardiac contractions on the ECG. In what cases can the voltage and rhythm of the heart contractions be broken?

2. Determine the cardiac contractions rate on the ECG. How can it vary in the healthy persone and in the pathology?

3. Determine a position of the electrical axis of the heart. In what cardiac pathology does it deviate to the left and to the right?

4. Determine the duration of the P — Q (R) interval. In what cardiac pathology does it vary?

5. Determine the duration of the QRS interval. In what cardiac pathology does it vary?

6. Are there signs of a hypertrophy of one of auricles on ECG. In what pathology can be the atriums hypertropied?

7. Are there signs of a hypertrophy of one of ventricles on ECG. In what pathology does the ventricle hypertrofied?

8. Give the P-wave characteristic on the offered ECG; name the diagnostic value of this wave?

9. Give the T-wave characteristic on the offered ECG; name the diagnostic value of this wave?

10. Are there the atrial fibrillation or the atrial flutter take place on the ECG; in what pathology do these arrhythmias occur?

11. Determine the localization of the extrasystoles on ECG — supraventricular, ventricular or nodal. In what pathology do extrasystoles appear?

12. Does the attac of the paroxysmal tachicardia take place on the ECG? In what pathology does this arrhythmia occur?

13. Are the signs of the bundle His block on electrocardiogram? In what diseases do these occur?

14. Determine the degree (incomplete or complete) of atrioventricular blockade on the ECG. In what diseases do such blockades occur?

15. Are the signs of the myocardial infarctioin on ECG?
