yENTRICUIAR and supraventricular tachyeardias are occasionally resistant to drug therapy and may culminate in congestive heart failure, circulatory collapse, ventricular fibrillation, and death. In this paper are presented recent experiences with eight patients in whom tachyeardias were unresponsive to drug therapy and were terminated by external electric countershock, usually unider general an...

BACKGROUND Atrial fibrillation is the most frequent cardiac rhythm disturbance, with prevalence increasing with age. This disease is a major risk factor for ischaemic stroke. The costs resulting from atrial fibrillation are really impressive. Pharmacological agents are the first line therapy for the management of atrial fibrillation. Antiarrhythmic drugs are used to terminate arrhythmias, as ac...

THE EFFECT OF METHOXYFLURANE on the sensitivity of the heart to epinephrineinduced ventricular arrhythmias has not been clearly defined. On the one hand, animal experiments have been reported which found that methoxyflurane increases ventricular arrhythmias associated with epinephrine administration. 1,~ On the other hand, other studies have found that methoxyflurane protects against arrhythmia...

Atrial fibrillation is the most common cardiac arrhythmia in world, with an estimated prevalence of 2 to 4%, and represents a high burden disease worldwide. It defined as supraventricular tachyarrhythmia loss atrial activity, diagnosed by specific electrocardiographic findings. Its classification clearly defined, based on form presentation, duration resolution episodes. One pillars treatment th...

BACKGROUND Catheter ablation is assuming a larger role in the management of patients with cardiac arrhythmias. Conventional fluoroscopic catheter mapping has limited spatial resolution and involves prolonged fluoroscopy. The non-fluoroscopic electroanatomic mapping technique (CARTO) has been developed to overcome these drawbacks. OBJECTIVES To report the early and late outcome in patients wit...

s from the annual scientific meetings of the American College of Cardiology, American Heart Association, British Cardiac Society (Heart), European Society of Cardiology, and North American Society for Pacing and Electrophysiology between 2000 and 2003 were searched. Inclusion criteria for studies Studies were included only if they met all of the following criteria: N Randomised allocation of pa...

This study was designed to assess the prevalence of cardiac arrhythmias in a group of relatives of patients who had come to necropsy with hypertrophic cardiomyopathy. Another aim of the study was to assess the validity of an interventricular septal thickness of 1.3 cm or more, measured by echocardiography, as a diagnostic criterion of hypertrophic cardiomyopathy among relatives of cases proven ...

We retrospectively studied the clinical efficacy and safety of oral flecainide in 38 patients with symptomatic arrhythmias. Patients received 100 to 200 mg daily of flecainide for a mean of 25 months (range 8 to 50 months). All patients had normal cardiac function. Paroxysmal atrial fibrillation (PAF) was observed in 29 patients (76%). Other forms of arrhythmia included paroxysmal atrial flutte...

Flecainide is a class I antiarrhythmic used for supraventricular tachyarrhythmias with mild adverse reactions. We present case report in 78-year-old male that came to the emergency department atrial fibrillation and was subsequently treated flecainide. During infusion, patient went into cardiac arrest. Cardiopulmonary resuscitation performed until return of spontaneous circulation achieved afte...

Atrial tachycardia is an uncommon arrhythmia and may be focal or macroreentrant. This review concentrates on focal atrial tachycardia. Over the last decade there have been a number of advances in delineating the mechanism and anatomic locations of focal atrial tachycardia. The lack of efficacy of antiarrhythmic therapy and the advent of radiofrequency ablation have altered our primary approach ...
