The influence of atrial cycle length on the effective and functional refractory period of the human AV node and atrium is presented. In general, decrements in atrial cycle lengths resulted in a shortening of the refractory period of the atrium and the functional refractory period of the AV node. The effective refractory period of the AV node was not significantly prolonged. The physiologic significance of the effective and functional refractory periods of the AV node are discussed.
The unusual contour of the jugular venous pulse tracing (JVPT) in a patient whose tricuspid valve was excised is described. The appearance of an early positive systolic wave (SW) followed by a prominent "V" wave and a delayed deep "Y" descent were noted.
