Abstract
Overview: Premature ventricular contractions (PVCs) are common ventricular arrhythmias. Objectives: This study aims to describe the characteristics of PVCs on 24-hour Holter ECG and identify factors related to PVCs in hypertensive patients with type 2 diabetes. Methods: A cross-sectional study was conducted from April 2023 to March 2024 at Bac Lieu General Hospital. Sixty patients with both hypertension and type 2 diabetes, exhibiting PVCs, were included in the study. Results: Among the 60 patients included, 40% were men, with an average age of 65.5 ± 11.0 years. Palpitations were the most common symptom, reported by 31.7% of patients. According to Lown's classification, 65% of patients had simple PVCs, while 35% had severe PVCs. The median 24-hour PVC count was 388.5 (range: 142.5 – 2771.2), and the median 24-hour PVC rate was 0.3% (range: 0.1 – 5.4). Left ventricular hypertrophy on echocardiography was associated with severe PVCs. Conclusion: In hypertensive patients with type 2 diabetes, PVCs are predominantly simple. There is a correlation between severe PVCs and left ventricular hypertrophy.
