Abstract

Objective: This study aimed to characterize arrhythmias via 24-hour Holter electrocardiogram (ECG) in cardiovascular patients and to investigate some factors associated with arrhythmias. Subjects and methods: A cross-sectional, retrospective and prospective study on 198 cardiovascular patients with 24-hour Holter ECG from April 2024 to September 2025 at the Department of Cardiology - Geriatrics, Van Dinh General Hospital. Results: Arrhythmias were recorded on 24-hour Holter electrocardiograms with high frequency, in which atrial premature beats (39.9%), ventricular premature beats (34.3%) and supraventricular tachycardia were the three most common arrhythmia groups. The group of patients ≥ 60 years old accounted for a large proportion and tended to have more arrhythmias. Heart failure was a statistically significant factor associated with Holter-detected arrhythmias. No significant association was observed between gender, hypertension, or diabetes mellitus and the incidence of arrhythmias. Conclusion: The study showed that atrial premature beats, ventricular premature beats and supraventricular tachycardia were the most common arrhythmias. Dizziness/lightheadedness was a common symptom. Older age and heart failure were factors associated with the occurrence of arrhythmias in the study group.
