In a population of 690 patients with Wolff-Parkinson-White (WPW) syndrome referred to our hospital from January 1979 to February 1995, 15 patients (2.2%) had an aborted sudden death out of the hospital. This retrospective study examines their clinical and electrophysiologic characteristics. Gender, accessory pathway localization, and presence of multiple(More)
Atrial fibrillation (AF) is the most common cardiac arrhythmia and entails an increased risk of thromboembolic events. Prediction of the termination of an AF episode, based on noninvasive techniques, can benefit patients, doctors and health systems. The method described in this paper is based on two-lead surface electrocardiograms (ECGs): 1-min ECG(More)
OBJECTIVE To evaluate characteristics of patients and accessory pathways as well as additional technical factors involved in the reappearance of accessory pathway conduction after successful ablation. DESIGN Analysis of recurrences after radiofrequency ablation. SETTING 163 consecutive patients with 167 accessory pathways. SUBJECTS 97 men and 66 women(More)
Atrial undersensing is a common problem in permanent atrial and dual chamber pacing. The purpose of this study was to evaluate the relationship between transesophageal atrial wave (EsAW) and right atrial endocavitary (RA). Forty-seven patients 72 +/- 9.7 years of age, with symptomatic bradyarrhythmias were studied. The EsAW was filtered with a high pass(More)
OBJECTIVES To examine the effect of isoprenaline on slow and fast pathway properties and tachycardia initiation. DESIGN Consecutive patients, prospective study. SETTING Referral centre for cardiology, academic hospital. PATIENTS 24 patients suffering from common type atrioventricular nodal reentrant tachycardia (AVNRT). INTERVENTIONS Programmed(More)
BACKGROUND In an 84-year-old patient with acute right ventricular myocardial infarction (RVI), complete heart block, and low cardiac output, a significant increase in blood pressure (BP) and decrease in right atrial pressure (RAP) were accidentally observed during the performance of high-rate ventricular pacing. METHODS Based on that observation, the(More)
The purpose of this study was to evaluate the effectiveness and safety of temporary VDD pacing using an esophageal electrode for sensing of the atrial electrogram. We studied 15 patients, 8 men and 7 women, aged 77 +/- 2 years (mean +/- SE, range 61-90), with severe atrioventricular (AV) conduction disturbances. A 24-hour beat-to-beat ECG analysis was used(More)
