No prospective studies have compared sotalol and amiodarone during electropharmacologic testing. The purpose of this prospective, randomized study was to compare the electrophysiologic effects of sotalol and amiodarone in patients with coronary artery disease and sustained monomorphic ventricular tachycardia (VT). Patients with coronary artery disease and sustained monomorphic VT inducible by p...

Introduction Catheter ablation is an effective and often preferred treatment for supraventricular tachycardia (SVT). Successful ablation is predicated on a precise diagnosis of the arrhythmia mechanism. The initial pacing maneuvers during electrophysiologic study (EPS) are often able to narrow the differential diagnosis immediately. We report an unusual case of SVT in which the initial findings...

Preliminary electrophysiologic topognostic test findings suggest a method for the functional localization and quantification of tinnitus; and provides a basis for the selection and monitoring of treatment. Numerous and different locations of the tinnitus symptom have been identified. In our series approximately 24% of tinnitus patients were identified to have a peripheral origin; 35% originated...

OBJECTIVE To determine the contribution of electrophysiologic testing in the diagnosis and anatomical classification of myoclonus. METHODS Participants with a clinical diagnosis of myoclonus were prospectively recruited, each undergoing a videotaped clinical examination and battery of electrophysiologic tests. The diagnosis of myoclonus and its subtype was reviewed after 6 months in the conte...

The article pertains to the uncommon clinical case of a patient with a proximal neuropathy of the lower extremity. It outlines the electrophysiological evaluation and reviews the medical literature. The electrophysiologic test that most accurately revealed the neuropathy was the segmental somatosensory evoked potential (SEP) of the lateral cutaneous branch of the iliohypogastric nerve. It showe...

The present study. In this issue of the Journal (1) investigators from the University of Minnesota report the third in a series of studies focusing on the phenomenon of “neurally mediated snycope.” In the present study, six patients (Group I) who presented with “cardiovascular collapse apparently associated with cardiac asystole” underwent head-up tilt testing before and during infusion of isop...

OBJECTIVES Goal of this study was to assess the long-term reproducibility of electrophysiologic drug testing in patients with ventricular tachyarrhythmias (VT/VF). BACKGROUND Programmed ventricular stimulation (PVS) is still widely used to guide antiarrhythmic therapy in patients with sustained ventricular tachycardia/fibrillation (VT/VF). Sotalol is considered as one of the most effective dr...

Sixteen postmenopausal women underwent electrophysiologic study before and 20 minutes after the administration of sublingual estradiol 17beta or placebo. Estradiol 17beta significantly affected electrophysiologic parameters, thereby suggesting its role in the development of palpitations in women.
