title: [A cardiac electric field on the body surface in rats with left ventricular hypertrophy caused by experimental renovascular hypertension].
abstract: The dynamics of potential distribution of cardiac electric field on the body surface was studied in renovascular hypertensive rats (Goldblatt type) during the ventricular activity. Three inversions of the mutual location of positive and negative areas of the cardiac electric field on the body surface were found in normotensive and hypertensive rats during the QRS-T period. Left ventricular hypertrophy of the heart in rats caused by renovascular hypertension results in changes of temporal and amplitude characteristics of the body surface potential distribution during the initial and terminal ventricular activity. The shifting trajectory of the positive and negative areas and their extremal ranges on the body surface does not change during the ventricular activity in rats with left ventricular hypertrophy of the heart as compared to the initial normotensive state.
