Shock-induced figure-of-eight reentry in the isolated rabbit heart.
The patterns of transmembrane potential on the whole heart during and immediately after fibrillation-inducing shocks are unknown. To study arrhythmia induction, we recorded transmembrane activity from the anterior and posterior epicardial surface of the isolated rabbit heart simultaneously using 2 charge-coupled device cameras (32,512 pixels, 480 frames/second). Isolated hearts were paced from ...
متن کاملRole of the perinodal region in atrioventricular nodal reentry: evidence in an isolated rabbit heart preparation.
To evaluate the role of perinodal tissue in the genesis of atrioventricular (AV) nodal reentry, echo beats were induced by programmed stimulation in nine superfused rabbit atrial-atrioventricular nodal preparations. In these preparations, extracellular bipolar electrograms were recorded simultaneously from the crista terminalis, interatrial septum arid His bundle, along with microelectrode acti...

15 صفحه اولMetabolism in Isolated Rabbit Heart
To investigate whether energy derived from glycolytic and oxidative metabolism are preferentially used for different functions in heart, tension, intracellular potential, and extracellular [K+] and pH (using triple barrel K/pH electrodes, tip diameter 0.5 mm) were monitored in isolated arterially perfused rabbit interventricular septa during exposure to hypoxia and metabolic inhibitors. Myocard...
