01 Data are presented as mean [+ or -] SD * Student t-test AERPD - atrial effective refractory periods
dispersion, AVWCL - Wenckebach cycle length of A-V conduction, DM--diabetes mellitus, HLAERP--high left atrium effective refractory period
, HRAERP--high right atrium effective refractory period
, IACT--inter-atrial conduction time, LLAERP--low left atrium effective refractory period
For example, the medial preoptic area (MPOA) has been shown to be important for sexual arousal, copulatory behaviour, and the refractory period
of male rats (Hoffman, Gerall, & Kalivas, 1987; Oomura, Aou, Koyama, Fujita, & Yoshimatsu, 1988).
The refractory period
can be accompanied by an intense desire to turn over and start snoring.
The right bundle branch normally has the longest refractory period
of any part of the conduction system (1).
CCM is a method for treating failing hearts in which non-excitatory impulses are delivered to the heart during a period of time called the absolute refractory period
For a while, mainly depending on his age and health, he won't be able to achieve another erection for some time - the so-called refractory period
- and therefore his interest in sex lessens.
In this patient's electrocardiogram the sinus-initiated P waves and the junction-initiated QRSs occur virtually simultaneously, and each occurs in the absolute refractory period
of the other so that there are no atrial or ventricular captures.
