We studied atrial flutter due to circus movement in chronically instrumented conscious dogs to identify the mechanism by which class I and class III antiarrhythmic drugs terminate reentrant excitation. We used a crossover experimental design administering five class I agents and one class III agent, by intravenous bolus followed by intravenous infusion. The class I agents other than lidocaine w...
BACKGROUND Based on epicardial mapping, different mechanisms of termination of reentrant ventricular tachycardia by various pharmacological interventions are described. METHODS AND RESULTS In 40 Langendorff-perfused rabbit hearts, rings of anisotropic left ventricular epicardium were made by a cryoprocedure. Sustained monomorphic ventricular tachycardia based on continuous circus movement of ...
BACKGROUND We conducted a prospective, multicenter, randomized comparison of implantable cardioverter-defibrillator (ICD) versus antiarrhythmic drug therapy in survivors of cardiac arrest secondary to documented ventricular arrhythmias. METHODS AND RESULTS From 1987, eligible patients were randomized to an ICD, amiodarone, propafenone, or metoprolol (ICD versus antiarrhythmic agents randomiza...
BACKGROUND Recent in vitro studies have demonstrated regional differences in electrophysiological properties of individual left ventricular muscle layers. Controversy exists on the relevance of these findings for the situation in vivo. Thus, this study was designed to determine whether the in vivo canine heart exhibits regional differences in left ventricular refractoriness and in the susceptib...
In case you may not have noticed, there is currently a “turf war” going on between cardiologists and electrophysiologists as to which treatment, pharmaceutical drugs or catheter ablation, should be officially pronounced as the first-line treatment for atrial fibrillation. The newest gambit is the finding by a team of cardiologists that treatment with rhythm control drugs such as flecainide and ...
AD, anterior descending coronary artery; CTO, chronic total occlusion; CX, circumflex coronary artery; F, female; LMC, left main coronary artery; M, male; RC, right coronary artery. a Patient no. 4 had chronic renal failure requiring hemodialysis, as well as severe peripheral arterial disease. Patient no. 7 had advanced chronic obstructive pulmonary disease. b Patient no. 4 had total occlusion ...
