Electrophysiological abnormalities in the transplanted human heart.
Fourteen relatively long term survivors of cardiac transplantation underwent systematic electrophysiological evaluation and ambulatory electrocardiographic monitoring. Six patients had prolonged conduction intervals during sinus rhythm. Sinus node function could be assessed in all donor atria and in 10 recipient atria. Sinus node recovery times were prolonged in four of the donor atria and in s...
متن کاملElectrophysiological Studies In the Denervated Transplanted Human Heart
To date, no studies have documented the conduction characteristics of the atrioventricular conduction system in the transplanted human heart. Three patients who had undergone cardiac transplantation 1—2 years previously formed the basis of this study. All were functional class I symptomatically and had normal hemodynamics and coronary arteriograms at the time of study. Each patient was in sinus...
متن کاملElectrophysiological effects of edrophonium in the innervated and the transplanted denervated human heart.
In order to determine the mechanism of action of edrophonium on the cardiac conduction system, we used His bundle recording and pacing techniques to examine the electrophysiological effect of edrophonium in 6 patients undergoing diagnostic evaluation for coronary artery disease and in 9 cardiac transplant recipients who were free of acute graft rejection. After control measures were made of sin...

متن کاملElectrophysiological effects of adenosine in the transplanted human heart. Evidence of supersensitivity.
After cardiac transplantation, the denervated donor atria and ventricles demonstrate increased sensitivity to infusions of sympathomimetic amines. Recently, supersensitivity of the canine sinus and atrioventricular (AV) nodes to acetylcholine has also been demonstrated after parasympathetic denervation. Acetylcholine and the endogenous nucleoside adenosine exert similar electrophysiological eff...
