ECG Intepretation
- Sinus rhythm, rate 88/min, with frequent multifocal ventricular extrasystoles
- Normal PR interval
- Normal axis
- Q waves in leads II, III, VF
- T waves flattened or inverted in the sinus beats in leads II, III, V5–V6
Clinical Interpretation
The ECG shows a probable old inferior myocardial infarction, which accounts for his angina. Ventricular extrasystoles are in themselves usually not important, but in a patient complaining of attacks of dizziness, ventricular extrasystoles that are frequent and multifocal may be causing haemodynamic impairment.
What to do ?
It would be worth recording an ambulatory ECG to see if the patient is having runs of ventricular tachycardia, but the extrasystoles probably do need suppressing. A beta-blocker would be the first drug to try.
