Cardiac electric field during ventricular depolarization of ISIAH rats with various degrees of arterial hypertension

The spatial characteristics of cardiac electric field on the body surface of rats with arterial hypertension (ISIAH line) with different levels of systolic blood pressure were investigated. Significant differences of displacement trajectories of positive and negative extrema were revealed in accordance with the degree of increase of systolic blood pressure at the same changes of the initial ventricular complex in ECG in limb leads in animals with severe and moderate arterial hypertension in the dynamics of cardiac electric field on the body surface.
