Arrhymias in hypertensive left ventricular hypertrophy (LVH) patients by 24-hour Holter ECG

ABSTRACT

The study on 24-hour ambulatory eclectrocardiographic monitoring for 74 hypertensive patients (34 had LVH) without coronary heart disease, diabetes and 34 normal people, the groups were matched for age, sex, BMI, risk factors. Results: the frequency of supraventricular, ventricular arrhythmias and complex ventricular arrhythmias (Lown grade 3-5) in hypertensive patients, especially hypertensive left ventricular hypertrophy patients, were significantly higher than in control group. Arrhymias in hypertensive patients were associated with age, LVM. The hypertension increased the risk of supraventricular arrhythmias by 7.2 folds, ventricular arrhythmias by 7.4 folds. The hypertension with LVH increased the risk of ventricular arrhythmias by 4.04 folds, especially increased the risk of complex ventricular arrhythmias to 7.6 folds in comparison with hypertension without LVH
