Tachyarrhythmias in acute myocardial infarction: A study conducted in Aarupadai Veedu Medical College
Journal Title: MedPulse -International Medical Journal - Year 2017, Vol 4, Issue 6
Abstract
Background: Acute myocardial infarction predisposes a patient towards arrhythmias, which occur mostly during or immediately after the event. ST elevation myocardial infarction is more frequently associated with arrhythmias than with NSTEMI. Aims and Objectives: To study the types of tachyarrhythmias occurring in acute myocardial infarction. Materials and Methods: The study was conducted on patients admitted to the intensive coronary care unit with acute myocardial infarction in Aarupadai Veedu Medical College, Pondicherry. The duration of the study was one year. A thorough case history, meticulous physical examination, serial ECGs, cardiac enzymes and echocardiogram were recorded during their ICU stay. Results: It was observed that 54.3% of patients had some form of tachyarrhythmia. Among the males 50% had tachyarrhythmia and among females, 71.4% had tachyarrhythmias. The risk factors associated were diabetes and hypertension. Common tachyarrhythmias observed in the study were VPDs (31.6%), sinus tachycardia (26.3%), ventricular tachycardia (26.3%), APCs (10.5%) and atrial fibrillation (5.3%). Conclusion: Ventricular premature depolarizations were the commonest tachyarrhythmia encountered in our study. Majority of these arrhythmias occurred in anterior wall myocardial infarction and in male patients with hypertension as a risk factor and females with diabetes as a risk factor.
