Abstract The Framingham Study has indicated that patients with left ventricular hypertrophy (LVH) have a greater risk of cardiovascular complications and sudden death than subjects with a normal heart. We have previously demonstrated that ventricular ectopy was more prevalent and complex in hypertensive patients with LVH by electrocardiographic (ECG) criteria than in those without ECG evidence of LVH. The present study was designed to detect and quantify ventricular dysrhythmias in hypertensive patients with early concentric LVH by echocardiography but without LVH by ECG criteria. Continuous ambulatory ECG tracings were recorded for 24 hours in 94 patients with essential hypertension: 37 without LVH, 26 with concentric LVH by echocardiographic but not ECG criteria, and 31 with LVH on both echocardiography and ECG. Patients with LVH by ECG criteria had significantly more premature ventricular contractions (P less than .001) and more complex (higher Lown's class) ventricular ectopy (P less than .001) than hypertensives without LVH or with LVH only by echocardiographic criteria. Prevalence and complexity of ventricular ectopic activity, however, was not affected by mild to moderate concentric cardiac hypertrophy detected echocardiographically. We conclude that unlike LVH shown by ECG, early hypertensive concentric LVH detected echocardiographically is not associated with increased electrical irritability of the myocardium.
