Sino-atrial reciprocation in the isolated rabbit heart.
Reciprocal beats between sinus node and atrium were studied in isolated rabbit heart tissue by microelectrode techniques. Early premature atrial responses which entered the sinus node frequently emerged to re-excite the atrium as "echoes." When the premature atrial beats discharged some but not all nodal areas, the atrial echoes, in turn, appeared to re-enter the sinus node. Repetitive reciproc...
متن کاملMetabolism 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...
متن کاملModulation of extracellular atrioventricular node field potential pattern and ventricular rhythm by morphine in experimental atrial fibrillation in isolated rabbit heart
Introduction: Endorphins are produced by cardiomyocytes, and exert different effects on the heart. The aim of the present study is to assess morphine effects on extracellular atrioventricular (AV) node field potential pattern and ventricular rhythm of isolated rabbit heart during experimental atrial fibrillation (AF). Methods: Effects of different concentrations of morphine (10, 20, 50 and 1...
متن کاملFacilitation of the L-type calcium current in rabbit sino-atrial cells: effect on cardiac automaticity.
OBJECTIVE The L-type Ca(2+) current (I(Ca,L)) contributes to the generation and modulation of the pacemaker action potential (AP). We investigated facilitation of I(Ca,L) in sino-atrial cells. METHODS Facilitation was studied in regularly-beating cells isolated enzymatically from young albino rabbits (0.8-1 kg). We used the whole-cell patch-clamp technique to vary the frequency of the test de...
متن کاملThe Wenckebach phenomenon in sino-atrial block.
Disturbances in conduction analogous to those occurring at the atrio-ventricular (A-V) node may be present at the sino-atrial (S-A) junction. When second degree block occurs at the S-A junction, it may adopt the form of the Wenckebach phenomenon. Early descriptions of this arrhythmia were presented by Wenckebach (1906), Rihl (1908), and Wenckebach and Winterberg (1914). There have been relative...
