Resumen

CONCEPCION MILIAN, Ariadna et al. Regresión eléctrica de hipertrofia ventricular izquierda. Rev cubana med [online]. 2003, vol.42, n.6. ISSN 0034-7523.

The left ventricular hypertrophia (LVH) is an independent cardiovascular risk factor and its regression is connected with an important decrease of cardiovascular morbidity and mortality. The electrocardiographic regression of LVH has been poorly studied A clinical assay was made in 34 patients over 50 with arterial hypertension and chronic coronary syndrome to determine the regression of electrocardiographic signs of LVH by using two treatment strategies (calcium antagonists and non-calcium antagonists). Patients had the electrocardiograophic sign of LVH, Casale, due to the duration of the QRS complex. An electrocardiogram was performed (in a Cardiocid-BS automated equipment) at the beginning of the study and another a year after treatment. The results were appropriately compared with those obtained at the beginning by X2 or by Student t for quantitative or qualitative dependent data. It was observed that the regression of Casale sign due to QRS duration was higher with the strategy based on calcium antagonists (p < 0.05) compared with the non-antagonists (p = ns). It was concluded the electrocardiographic signs of the LVH may disappear with treatment The strategy based on the use of verapamil was more effective than the one based on atenolol.
