Abstract

Background: Arrhythmias and conduction disturbances those are likely to be significant problems during the early phases of AMI. The arrhythmias and conduction abnormalities discussed include sinus bradycardia, AV block, Idioventricular rhythm, VT, and VF. In general, the acute management of these rhythm disturbances is the same in the early and in the late phases of AMI
Materials & Methods: The present study was conducted in 100 patients of acute myocardial infarction to evaluate the incidence and significance of early and predischarge cardiac arrhythmias.
Results: By seventh hospital day, twenty patients had expired and the remaining eighty patients were monitored in CCU for two hours and arrhythmias were noted. Complicated ventricular premature contraction (i.e.Lown class III-V) was observed in two (25%) patient. Fifteen (18.75%) patients had Lown class 0-II VPC's. Two (2.5%) patients had supraventricular tachycardia and 6 (7.5%) patients had heart blocks.
Conclusion: Early arrhythmias (within 24 hours of AMI.) were significantly associated with in hospital mortality and complicated course, while no significant bearing on long term (6 month) cardiac event was noted.
