ASSOCIATION OF VENTRICULAR LATE POTENTIALS WITH LEFT VENTRICULAR HYPERTROPHY IN PATIENTS WITH SYSTEMIC ARTERIAL HYPERTENSION

Objective: To determine the association of ventricular late potentials with left ventricular hypertrophy in patients
with systemic arterial hypertension.

Study Design: Cohort retrospective study.
Place and Duration of Study: Department of Cardiac Electrophysiology, Armed Forces Institute of Cardiology,
Rawalpindi from 11
th Nov, 2014 to 10th Nov, 2015.
Material and Methods: Sixty four patients with systemic arterial hypertension were divided into two equal
groups on the basis of left ventricular hypertrophy. Patients with acute or old myocardial infarction, diabetes
mellitus, cerebrovascular accident, heart failure, structural heart disease, bundle branch block and
cardiomyopathies were excluded from the study. DMS 300 4L Holter monitors were used to obtain 3 channel
signal averaged ECG recording. CardioScan premium luxury software was used for analysis of ventricular late
potentials.

Results: There were 49 (76.6%) males and 15 females (23.4%) with the mean age of 60 ± 11.83 years. Ventricular
late potentials were revealed in 10 (31.3%) out of 32 patients with left ventricular hypertrophy whereas in patients
without hypertrophy only 1 (3.1%) patient showed it. Ventricular late potentials were strongly associated with
left ventricular hypertrophy (
p-value=0.03) and the relative risk of developing ventricular late potentials was 10
times higher in patients with left ventricular hypertrophy as compared to those without left ventricular
hypertrophy.

Conclusion: Ventricular late potentials were strongly associated with left ventricular hypertrophy.
Keywords: Left ventricular hypertrophy, Systemic arterial hypertension, Ventricular late potentials.
