    Abstract:
    Various studies have established the increase of sudden death in hypertensive patients with left ventricular hypertrophy (LVH). In order to specify its most important factors, an electrophysiological study consisting of Holter recording (HR) and programmed ventricular stimulation (PVS), was performed in 24 patients with hypertension: 12 with LVH and 12 without LVH, on ultrasonography. In all patients, coronary angiography was normal. The results are the following: 1) LVH increases the ventricular vulnerability, this arrhythmogenic substrate and its stability are explored by PVS; 2) HR and PVS are not correlated, therefore HR does not explore the arrhythmogenic substrate of LVH, but rather the potential triggering factors of severe rhythm disorders; 3) it has not been possible to evaluate the role of the autonomous nervous system in this study; 4) finally, a significant correlation was found between the degree of anatomical hypertrophy of the LV and the duration of the interval AH.
