[Hemodynamic characteristics during 2-chamber electrostimulation of the heart].
1987
: Cardiac output was investigated in coronary patients with temporary (15) and permanent (16) programmed two-chamber electrostimulation of the heart, using different induced atrioventricular interval values. The study was based on integral rheoplethysmography, peripheral volumetric sphygmography, sectoral echocardiography and two-dimensional doppler echocardiography with color code. The adjustment of atrioventricular interval in two-chamber cardiac electrostimulation can modulate cardiac output by means of changing the duration and rate of left-ventricular filling flow, produced by the atrial systole.
