Effect of Hypoxia on the Sinoatrial Node, Atrium, and Atrioventricular Node in the Rabbit Heart

We used intracellular microelectrodes to study the effects of hypoxia on the isolated, superfused sinoatrial (SA) node, atrium, and atrioventricular (AV) node of the rabbit heart. Hypoxia decreased the rate of spontaneous impulse initiation in SA nodal fibers by decreasing the slope of diastolic dep...
