Depressant effect of digoxin on atrioventricular conduction in man.
We examined the effect of chronically administered digoxin on atrioventricular (A-V) conduction in nine cardiac transplant recipients. We assessed A-V conduction by measuring the duration from the pacing stimulus to the onset of the QRS complex (S'R interval) and by determining the occurrence of Wenckebach periodicity during rapid atrial pacing. We made measurements during a control period and ...
متن کاملThe effect of phentolamine on atrioventricular conduction in man.
The effects of phentolamine, 0.3 mg/mm given intravetient and it had no effect on the HQ or HS intervals. This nopsly for 15 minutes, on atrioventricular and intravenrepresents ao improvement in conduction through the tricular conduction were studied in seven cardiac patients atrioventricular node. Phentolamine had no effect on aod in four normal subjects. Recordings were made at atrioventricul...
متن کاملEvidence of concealed atrioventricular conduction in man.
THE TERM "concealed conduction" was introduced by Langendorfl to describe the phenomenon of entry of an electrical impulse into the A-V node without complete transmission but with modification of conduction of a subsequent impulse. This concept unified diverse observations of earlier years concerning disturbances of A-V transmission2-4 and clarified the mechanisms of many arrhythmias.5 6 Subseq...
متن کاملEffect of Digoxin on Atrioventricular Conduction Studies in Patients with and without Cardiac Autonomic Innervation
The effect of digoxin on atrioventricular (A-V) conduction-was compared in five patients with an intact cardiac autonomic nervous system (Group I) and seven patients who had undergone cardiac transplantation (Group II), in whom we have previously shown the transplanted heart to be completely denervated.Small decreases in the atrial effective refractory period (ERP) (from 262 ± 12 to 254 ± 11 ms...
متن کاملEffect of digoxin on A-V conduction.
The effect of digoxin on A-V conduction in 19 patients with known disease of their conduction tissue was studied while a demand pacing system was in position. Fifteen had transient complete heart block after myocardial infarction and four had chronic intermittent complete heart block. The patients were studied on return to sinus rhythm.In no instance was a return to either second- or third-degr...
