It has recently been shown that the probability of successful defibrillation as a function of
energy has a sigmoidal dose‐response relationship. Determination of a defibrillation “dose‐…

Electrophysiologic testing is warranted in patients with the Wolff-Parkinson-White (WPW)
syndrome presenting with rapid atrial fibrillation (AF) or ventricular fibrillation. Indications are …

A sequential pulse system for internal cardiac defibrillation incorporating catheter and patch
electrodes with two current pathways has been shown to reduce defibrillation threshold in …

The aim of this study was to determine the relative sensitivity, specificity, accuracy,
andtolerance of dobutamine and dipyridamole stress echocardiography in patients with a lower …

Autonomic neural tone modulates arrhythmias and could affect the efficacy of an implantable
defibrillator if defibrillation threshold is also altered by changes in neural activity. We …

The development of the automatic implantable defibrillator has created the need to assess
the effects of interventions on defibrillation success. However, first it is important to determine …

Intraoperative modification of the atrioventricular (AV) node to prolong refractoriness could be
an alternative to His bundle ablation in patients with refractory supraventricular arrhythmias…

Cardiac pacing is often considered in patients with recurrent syncope after repeated attempts
to document the cause have failed. To assess the results of this tactic we reviewed the …

Although ventricular fibrillation is a well known sequel to atrial fibrillation in the Wolff-Parkinson-White
syndrome, ventricular fibrillation is not generally associated with supraventricular …

A 12-year-old girl presented with recurrent episodes of supraventricular tachycardia. A 12
lead electrocardiogram showed normal sinus rhythm with a normal PR interval and no …
