ARRHYTHMIAS IN PATIENTS WITH ACUTE MYOCARDIAL INFARCTION AND SOME ASSOCIATED FACTORS THESE ARRHYTHMIAS IN PATIENTS TREATED AT HANOI MEDICAL UNIVERSITY HOSPITAL
Main Article Content
Abstract
Objective: Identify arrhythmias noted on a 24-hour electrocardiogram holter in patients with acute myocardial infarction and identify a number of associated factors these arrhythmias in patients treated at Hanoi Medical University Hospital for the period April 2022 - April 2023. Results: Common arrhythmias on 24-hour electrocardiogram holter in patients with acute myocardial infarction were ventricular extrasystole accounting for 53.33%, extraventricular systole with 56.67%, atrial tachycardia with 26.67%. There were 5 patients with dangerous arrhythmias include 1 patient had ventricular tachycardia, 2 patients had new atrial fibrillation, 2 patients had completely irreversible atrioventricular block. Dangerous arrhythmias increased in patient >70 years (p=0.005), patients who received late coronary revascularization more than 48 hours after symptom onset (p=0.036). Conclusion: Arrhythmia is common in the early stages in patients with acute myocardial infarction. Old age, late coronary artery revascularization after symptom onset as warning signs of dangerous arrhythmias in these patients.
