Abstract: PURPOSE--To study the presence and type of ventricular arrhythmias in patients with different geometric patterns of the left ventricle (LV). METHODS--Seventy-two patients with essential hypertension were divided in 4 groups, by the echocardiographic patterns: group I with concentric remodeling of the LV (normal LV mass with increased relative wall thickening); group II with concentric hypertrophy (both LV mass and relative wall thickening increased); group III with normal geometry of the LV (both LV mass and relative wall thickening normal); group IV, with eccentric hypertrophy (increased LV mass with normal relative wall thickening). The groups were compared by the quantity and quality of ventricular arrhythmia, measured by the number of ventricular ectopic beats (VEB) and episodes of ventricular tachycardia (VT) on Holter monitoring, and the presence of late potentials (LP) on signal-averaged electrocardiogram. RESULTS--Group I showed fewer VEB than group II (16.2 +/- 12.85 x 996.4 +/- 518.8, p < 0.05), and a statistic tendency to this result when compared with group IV (16.2 +/- 12.85 x 1634.2 +/- 1001.33, p = 0.063). When compared with group III, no statistical difference was found (16.2 +/- 12.85 x 19.8 +/- 14.81, p = NS). Episodes of VT and the presence of LP were noted only in groups II and IV. CONCLUSION--The group with concentric remodeling of the LV had fewer ventricular arrhythmias than hypertrophic groups, with characteristics closer to the patients with normal LV geometry.
