In 10 patients, 24 episodes of supraventricular tachycardia were treated by rapid electrical stimulation of the right atrium. One episode of sinus tachycardia, eight episodes of atrial tachycardia, two episodes of atrial flutter, and 13 episodes of A-V junctional tachycardia occurred. In each case the diagnosis of the arrhythmia was documented by obtaining unipolar and bipolar intra-atrial elec...

BACKGROUND AND PURPOSE Patients with acute cerebrovascular events are susceptible to serious cardiac arrhythmias, but data on the time course and the determinants of their onset are scarce. METHODS The prospective Stroke-Arrhythmia-Monitoring-Database (SAMBA) assessed cardiac arrhythmias with need for urgent evaluation and treatment in 501 acute neurovascular patients during the first 72 hour...

Background Atrial fibrillation (AF) is the most common sustained arrhythmia, cause of supraventricular tachycardia in global population and arrhythmia requiring treatment an emergency department. Objectives To systematically review recent literature quantify correlation between choice pharmacological cardioversion (PCV) drug national or international guidelines. Material methods A systematic wa...

Electrophysiologic studies (EPS) were performed in 155 patients with hypertrophic cardiomyopathy (HCM). Indications for EPS were cardiac arrest in 22 patients, syncope in 55 patients, presyncope in 37 patients, asymptomatic ventricular tachycardia (VT) in 24 patients, palpitations in 10 patients, and a strong family history of sudden cardiac death in seven patients. Thirty-five (23%) patients h...

A 25 year old man underwent electrophysiology study for recurrent symptomatic paroxysmal palpitations. There were no documented episodes of supraventricular tachycardia on surface ECG. Delta waves were absent on baseline ECG. A decapolar catheter was placed in the coronary sinus with the distal and proximal pair of electrodes configured as CS 1-2 and CS 9-10 respectively. Quadripolar catheters ...

Atrial fibrillation is the most common form of supraventricular arrhythmia. In its chronic form, it poses an increased risk of thromboembolic events, especially for people in advanced age. As this disease entails a reduced quality of life and increased mortality for the affected individuals, it is of the utmost importance that a physician knows the different forms of this widespread disease ver...

Paroxysmal supraventricular tachycardia (PSVT) is commonly caused by reentry within the atrioventricular (AV) node. This arrhythmia was abolished by operative dissection of the AV junction in a patient with disabling tachycardia that was not controlled by drugs. The operation was intended to create complete AV block, but AV conduction persisted after surgery. An electrophysiologic study 1 year ...

Supraventricular tachycardia (SVT) is the most common arrhythmia in the pediatric population. Despite its commonality, presentation of SVT can be nonspecific and varies based upon age with infants demonstrating fussiness or irritability and older children reporting vague perceptions of tachycardia or palpitations. Furthermore, SVT may manifest as self-limited paroxysms or with prolonged runs of...

INTRODUCTION Azimilide hydrochloride is an investigational antiarrhythmic medication that had shown evidence of efficacy in prolonging the time to recurrence of atrial fibrillation (AF) or atrial flutter (AFL) and paroxysmal supraventricular tachycardia (PSVT). This study was designed to confirm efficacy of 125 mg daily azimilide. METHODS AND RESULTS The primary endpoint was ECG-documented re...
