985 | [Long-term preventive effect and safety of amiodarone in patients with paroxysmal atrial fibrillation refractory to class I antiarrhythmic agents: analysis based on patient profiles]. | The factors controlling the preventive effect of long-term amiodarone therapy were evaluated in patients with paroxysmal atrial fibrillation. The 55 patients (37 men and 18 women, mean age 68 +/- 9 years) with paroxysmal atrial fibrillation refractory to more than two types of Class I antiarrhythmic agents received ami... |
986 | [Stroke and other thromboembolic complications of atrial fibrillation. Part VI. Choice of optimal approach and drugs for prevention of stroke]. | In part VI of a series of papers on epidemiology and drug prevention of stroke and other thromboembolic complications of atrial fibrillation the authors analyze data of randomized trials comparing various approaches to the treatment of atrial fibrillation: cardioversion with subsequent use of antiarrhythmic drugs for m... |
987 | [The role of atrial pressure in spontaneous initiation of atrial fibrillation in the dog.]. | Atrial fibrillation (AF) frequently occurred under conditions associated with atrial dilatation (stretch) or vagal hyperactivity. To study possible role of atrial stretch in spontaneous initiation of vagal AF we compared changes of right atrial pressure (RAP) and activation patterns during AF beginning. In anesthetized... |
988 | Preventing alternans-induced spiral wave breakup in cardiac tissue: an ion-channel-based approach. | The detailed processes involved in spiral wave breakup, believed to be one major mechanism by which tachycardia evolves into fibrillation, are still poorly understood. This has rendered difficult the proper design of an efficient and practical control stimulus protocol to eliminate such events. In order to gain new ins... |
989 | Effect of statin therapy on risk of ventricular arrhythmia among patients with coronary artery disease and an implantable cardioverter-defibrillator. | Hydroxymethylglutaryl coenzyme-A reductase inhibitors, or statins, have been shown to decrease mortality rates in patients who have coronary artery disease. It has been postulated that part of the mortality benefit conferred by statins is due to a decrease in ventricular arrhythmias. We assessed the effect of statin th... |
990 | Cardiovascular abnormalities in hyperthyroidism: a prospective Doppler echocardiographic study. | We investigated the prevalence and clinical importance of cardiovascular abnormalities in patients with hyperthyroidism.</AbstractText>All consecutive patients diagnosed with hyperthyroidism during a period of 24 months were included in the study. Medical history, complete physical examination results, electrocardiogra... |
991 | Endoventriculoplasty using autologous endocardium for anterior left ventricular aneurysms. | There is currently consensus that endoventriculoplasty is the treatment of choice for an anterior left ventricular aneurysm. We describe here a new technique of endoventriculoplasty using autologous endocardium for left ventricular anterior aneurysm.</AbstractText>From 1990 until 2003, 49 patients underwent endoventric... |
992 | Surgical treatment of atrial fibrillation; a systematic review. | In this review the efficacies of the alternative sources of energy (radiofrequency-microwave and cryo ablation; group I) and the classical 'cut and sew' Cox-Maze III (group II), which claims a 97-99% sinus rhythm (SR) success rate, were evaluated in the surgical treatment of atrial fibrillation (AF). A computerized sea... |
993 | Defibrillation and biphasic shocks: Implications for perianesthesia nursing. | Cardiac arrests, the majority of which are due to ventricular fibrillation (VF), are a significant threat to survival. The definitive therapy for cardiac arrests due to VF is rapid, early defibrillation. There have been several advances made to modern defibrillators to electively or emergently terminate lethal and nonl... |
994 | Electrophysiological evaluation of asymptomatic ventricular pre-excitation in children and adolescents. | Diagnostic assessment and treatment have been described in detail in symptomatic WPW syndrome, but little information exists about significance and prognosis of an incidentally found ventricular pre-excitation (VPE) in asymptomatic children. The aim of the study was to evaluate, retrospectively, the role of electrophys... |
995 | A new dual-chamber pacing mode to minimize ventricular pacing. | Despite the low long-term incidence of high-degree atrioventricular (AV) block and the known negative effects of ventricular pacing, programming of the AAI mode in patients with sinus node dysfunction (SND) remains exceptional. A new pacing mode was, therefore, designed to combine the advantages of AAI with the safety ... |
996 | Characteristics of bifocal pacing: right ventricular apex versus outflow tract. An interim analysis. | Bifocal RIGHT ventricular stimulation (BRIGHT) is an ongoing, randomized, single-blind, crossover study of atrial synchronized bi-right ventricular (RV) pacing in patients in New York Heart Association heart failure functional class III, a left ventricular ejection fraction <35%, left bundle branch block and QRS com... |
997 | Cardiac safety of neuromuscular incapacitating defensive devices. | Neuromuscular incapacitation (NMI) devices discharge a pulsed dose of electrical energy to cause muscle contraction and pain. Field data suggest electrical NMI devices present an extremely low risk of injury. One risk of delivering electricity to a human is the induction of ventricular fibrillation (VF). We hypothesize... |
998 | Value of pre-hospital discharge defibrillation testing in recipients of implanted cardioverter defibrillators. | Opinions vary regarding the need to perform defibrillation testing prior to hospital discharge in recipients of state-of-the-art cardioverter defibrillators (ICDs). Our protocol is to perform predischarge ICD testing 1 day after implant. This report includes 682 consecutive implants. Adverse observations at testing wer... |
999 | Changes in autonomic nervous activity after catheter ablation of atrial tachycardia arising from the atrioventricular annulus. | Radiofrequency (RF) catheter ablation of supraventricular tachycardias causes local parasympathetic denervation. This study used heart rate variability (HRV) to evaluate the effects of ablation of atrial tachycardia (AT) arising from the atrioventricular annulus (AVAT) on autonomic function. Ten patients with AVAT were... |
