Electrophysiologic effects of lidocaine in children.
The effects of intravenous lidocaine on the refractory periods of the atrium, AV node and right ventricular myocardium were studied using His bundle recordings and the extrastimulus technique with and without atrial and ventricular pacing. The drug was administered in an intravenous bolus dose of 1 mg/Kg followed by an infusion of 100 micrograms/Kg/min. The AH, HV intervals and resting sinus cy...
متن کاملPotentiation of cardiac electrophysiologic effects of verapamil after autonomic blockade or cardiac transplantation.
Cardiac electrophysiologic effects of verapamil in vivo are the result of both direct and indirect actions on the heart (the latter due to augmentation of sympathetic neural tone, diminution of parasympathetic neural tone, and increased circulating catecholamines). In this study we assessed the interaction of verapamil's direct and indirect actions on electrophysiologic properties of the heart ...
متن کاملElectrophysiologic and Hemodynamic Effects of Verapamil Correlation with Plasma Drug Concentrations
Verapamil was administered intravenously to 30 open-chest dogs and the electrophysiologic and hemodynamic effects of the drug were correlated with the corresponding plasma concentrations. At concentrations below 152 ng/ml, verapamil prolonged the A-H interval, abolished ventriculoatrial conduction, but did not significantly change sinus rate, cardiac output, left ventricular dp/dt, or systemic ...
متن کاملComparative clinical and electrophysiologic effects of adenosine triphosphate and verapamil on paroxysmal reciprocating junctional tachycardia.
The efficacy, electrophysiologic effects, and side effects of adenosine triphosphate (ATP) and verapamil in the short-term management of paroxysmal reciprocating junctional tachycardia (PRJT) were compared in 20 patients. All patients had inducible sustained PRJT during control electrophysiologic study. Fourteen patients had PRJT involving a retrograde accessory pathway, and six patients had at...
