A canine model of myocardial infarction (MI) was used to study the type and frequency of ventricular antiarrhythmic and proarrhythmic effects due to procainamide and tocainide and the risk factors associated with development of proarrhythmia. An anterior MI was created by a 2-h occlusion of the left anterior descending artery (LAD) with complete(More)
BACKGROUND The INTRINSIC RV (Inhibition of Unnecessary RV Pacing with AVSH in ICDs) study tested the hypothesis that dual-chamber rate-responsive (DDDR) with atrioventricular search hysteresis (AVSH) 60-130 programming is not inferior to single-chamber (VVI)-40 programming in an implantable cardioverter defibrillator with respect to all-cause mortality and(More)
BACKGROUND A single catheter technique has been described for ablation in patients with Wolff-Parkinson-White syndrome. It is unknown how often omission of a standard electrophysiological study would lead to misdiagnosis based on an assumption that the manifest accessory pathway is responsible for clinical tachycardia. OBJECTIVES To examine the(More)
A 76-year-old woman presented with a 7-mm, hard, pink nodule at the site of an appendectomy scar of more than 70 years' duration. The clinical impression at the time of biopsy was that of a keloid. Surprisingly, light microscopic examination revealed classic histologic features of late-stage lichen sclerosus et atrophicus (LSA) overlying a scar. Elastic(More)
Radiofrequency catheter ablation is an accepted primary therapy for atrioventricular (AV) node reentrant tachycardia (AVNRT). There is concern that slow pathway ablation in patients with a long anterograde fast pathway effective refractory period (ERP) may potentially impair subsequent node conduction. Eighteen patients (14 women; age 53 +/- 20 years) with(More)
Complete postoperative evaluation of implantable cardioverter-defibrillators (ICDs) before discharge, including arrhythmia induction, has been the standard since their introduction. Whereas the original ICDs provided little telemetered information and used separate pace-sense and defibrillation leads, modern, third-generation devices provide pace-sense(More)
