Quantification of rate-dependent effects of verapamil, diltiazem, and digoxin on atrioventricular conduction

Autor: Decrinis M, Ingrid Schwarzl, U. Stark, Karin Kasper, Wolfgang Lindner, Gerhard Stark

Publikováno v: Journal of Pharmacological and Toxicological Methods. 36:205-210

The calcium channel blocking agents, verapamil and diltiazem, and the digitalis compound, digoxin, caused drug specific rate-dependent changes of the atrioventricular conduction time (AVCT). The purpose of this study was to investigate this rate adap

Effects of verapamil and diltiazem on the ventricular rate during simulated atrial flutter in isolated guinea pig hearts

Publikováno v: Journal of Pharmacological and Toxicological Methods. 35:203-209

To compare the direct effects of verapamil and diltiazem on the ventricular rate during atrial flutter, we developed an atrial flutter model in guinea pig isolated hearts. Atrial flutter was simulated by rapid atrial pacing (cycle length = 50 ms). At

Comparison of the Frequency-Dependent Effects on the Atrioventricular Node of Verapamil, Amiodarone, Digoxin, and Diltiazem in Isolated Guinea Pig Hearts

Autor: Helmut A. Tritthart, Karin Kasper, Christian Schulze-Bauer, U. Stark, Decrinis M, Gerhard Stark

Publikováno v: Journal of Cardiovascular Pharmacology. 25:330-335

To slow ventricular rate during supraventricular tachycardia, a drug must have a strong rate-dependent depressant effect on atrioventricular (AV) conduction. We investigated the frequency-dependent effects of verapamil, amiodarone, digoxin, and dilti

A comparison of the effects of adenosine and verapamil on the conduction and pacemaker system of isolated guinea pig hearts

Autor: Elisabeth Kickenweiz, Gerhard Stark, Maria Bachernegg, Decrinis M, Karin Kasper, Ulrike Stark

Publikováno v: Clinical Cardiology. 16:859-862

Adenosine and verapamil are effective in the treatment of supraventricular arrhythmias. Also, both substances can provoke sinus node arrest or a third-degree atrioventricular (AV) block with a ventricular escape rhythm. The aim of this study was to c

Influence of duration of rapid ventricular pacing on ventricular refractoriness in the presence of propafenone and lidocaine

Autor: Ingrid Schwarzl, Karin Kasper, Decrinis M, Ernst Pilger, Helmut A. Tritthart, Gerhard Stark, U. Stark

Publikováno v: Pacing and clinical electrophysiology : PACE. 20(1 Pt 1)

Propafenone and lidocaine have a rate dependent negative dromotropic effect on intraventricular conduction. We investigated the use dependent actions of propafenone and lidocaine on intraventricular conduction in isolated guinea pig hearts perfused b

How to measure AV nodal refractoriness in the presence of verapamil, amiodarone, digoxin, and diltiazem

Autor: Decrinis M, Gerhard Stark, Karin Kasper, Christian Schulze-Bauer, U. Stark, Helmut A. Tritthart

Publikováno v: Pacing and clinical electrophysiology : PACE. 19(2)

On the AV node the negative dromotropic action of verapamil, amiodarone, digoxin, and diltiazem is known to be rate dependent. The effective refractory period of the AV node (AV-ERP) at a short cycle length is related to the AV conduction at that cyc
