Multiform ventricular complexes: A transitional arrhythmia form?
American Heart Journal, 1989This study was undertaken to better characterize the role of multiform premature ventricular complexes in the classification of ventricular arrhythmias based on form and frequency. Twenty inpatients with organic heart disease and multiform ventricular complexes underwent continuous electrocardiographic monitoring with full disclosure analysis of the ...

Complex arrhythmia analysis in uraemic haemodialysed patients
International Urology and Nephrology, 1984Impulse formation and conduction disturbances of the heart were investigated in 23 uraemic patients with transvenous and oesophageal electrodes. Utilizing regular atrial pacing the sinoatrial conduction time (SACT) was obtained and sinus automaticity was evaluated by measurement of the sinus node recovery time (SNRT).

Cardiac Arrhythmias – Part II:Broad Complex Tachycardia . . .
Acute Medicine Journal, 2005The acute management of the patient presenting with a broad complex tachycardia is a daunting clinical challenge. A broad complex tachycardia may be ventricular or supraventricular in origin and the ability to interpret correctly the 12-lead electrocardiogram is of critical importance in this differentiation. Broad complex tachycardia should be assumed

Complex atrial arrhythmias studied by suction electrode technique
American Heart Journal, 1975Two elderly patients with coronary heart disease, chronic pulmonary disease, and complex atrial arrhythmias are presented. The suction electrode technique for right atrium monophasic action potential recording was used. This recording allows better analysis of the atrial arrhythmias and estimates the stability of focal activity.

Ethmozine® (moricizine HCl) therapy for complex ventricular arrhythmias
The American Journal of Cardiology, 1987Moricizine HCl (Ethmozine), a new antiarrhythmic agent, was administered to 102 patients with refractory ventricular fibrillation (n = 31), sustained ventricular tachycardia (VT) (n = 46) or symptomatic nonsustained VT (n = 25). A noninvasive approach utilizing monitoring and exercise testing was used in 82 patients who had a high density of ...

Introduction: Mapping and control of complex cardiac arrhythmias
Chaos: An Interdisciplinary Journal of Nonlinear Science, 2002This paper serves as an introduction to the Focus Issue on mapping and control of complex cardiac arrhythmias. We first introduce basic concepts of cardiac electrophysiology and describe the main clinical methods being used to treat arrhythmia. We then provide a brief summary of the main themes contained in the articles in this Focus Issue.

Suppression of complex ventricular arrhythmias by oral flecainide
Clinical Pharmacology and Therapeutics, 1982The effectiveness and safety of oral flecainide for suppression of complex ventricular arrhythmias was tested in nine patients in a short-term (4 wk), single-blind, placebo-controlled experiment. The prevalence of multiform premature ventricular complexes (PVCs), couplets and nonsustained ventricular tachycardia (VT) (less than 3 PVCs at rate less than

Evaluation of metoprolol in suppressing complex ventricular arrhythmias
The American Journal of Cardiology, 1983This study documents the extent of suppression of premature ventricular beats which can be achieved with metoprolol, a semiselective beta-adrenergic blocking agent, at doses of 100 to 200 mg daily, utilizing a single-blind placebo-controlled 10-day protocol with continuous ambulatory electrocardiographic recording of 20 patients with cardiac disease ...

Nonlinear dynamics, chaos and complex cardiac arrhythmias
Proceedings of the Royal Society of London. A. Mathematical and Physical Sciences, 1987Periodic stimulation of a nonlinear cardiac oscillatorin vitrogives rise to complex dynamics that is well described by one-dimensional finite difference equations. As stimulation parameters are varied, a large number of different phase locked and chaotic rhythms is observed.

Kir3 channel signalling complexes in cardiac arrhythmias
Drug Discovery Today: Disease Models, 2012G protein-modulated inwardly rectifying potassium channels (Kir3, GIRK) are crucial integrators of G protein-coupled receptor (GPCR) signalling and play key roles in the stabilization of resting membrane potential in excitable and non-excitable cells. Here we discuss their roles in the heart, with a specific focus on how they might be involved in two ...
