quinidine sulfate/心不全

Seventy-seven horses with atrial fibrillation (AF) were treated orally with quinidine sulfate (QS) at the University of Pennsylvania, School of Veterinary Medicine, Thirty-seven horses (48%) had adverse reactions to QS, the most common of which were nasal mucosal edema, anorexia, colic, and

Nine infants with episodic or continuous chaotic atrial rhythm (CAR) are presented. In addition to 3 or more different P-wave contours, atrial rates greater than 100 per minute, variable PP, RR, and PR intervals, and a discrete isoelectric baseline, findings included atrial rates that varied from a

With the use of glass syringes without heparin and all glass equipment, the percent of unbound quinidine was measured by ultrafiltration and a double-extraction assay method after addition of 2 microgram/ml of quinidine sulfate. Compared to the all-glass method, collection of blood using Vacutainers

Sixty-seven horses presented with atrial fibrillation (AF) from January 1, 1980 to August 1, 1986. All horses were evaluated for the type and severity of the underlying cardiac disease and the probable duration of the arrhythmia. Fifty-two (78%) of the horses were treated with quinidine sulfate

BACKGROUND QT interval prolongation and dispersion have been implicated in serious arrhythmias in congestive heart failure (CHF) and the congenital and drug-induced long-QT syndromes (LQTS). In a subset of the congenital LQTS, infusion of potassium can correct QT abnormalities, consistent with in

Cardiac involvement by systemic sarcoidosis is well known, but occurs rarely. It usually manifests as either heart block, heart failure due to direct myocardial involvement, or cor pulmonale. We present the case of a patient with cardiac sarcoidosis who had ventricular tachycardia and congestive
