Differentiation between aberrant ventricular conduction and ventricular ectopy in atrial fibrillation using RR interval scattergram.
BACKGROUND Differentiation between aberrant ventricular conduction and ventricular ectopy during atrial fibrillation (AF) is of etiologic, prognostic, and therapeutic importance. We developed a noninvasive technique to diagnose aberrant ventricular conduction and ventricular ectopy in AF. METHODS AND RESULTS We studied the Holter ECGs of 34 patients with paroxysmal AF and 62 patients with chr...
متن کاملEffect of sotalol on heart rate, QT interval, and atrial fibrillation cycle length in horses with atrial fibrillation
BACKGROUND Based on its pharmacokinetic profile and electrophysiological effects in healthy horses, sotalol potentially could be used as a long-term PO antiarrhythmic drug in horses. OBJECTIVES To evaluate the effect of sotalol on heart rate (HR), QT interval, atrial fibrillatory rate, and success of cardioversion in horses with naturally occurring chronic atrial fibrillation (AF). ANIMALS ...
متن کاملProlonged QTc interval predicts poststroke paroxysmal atrial fibrillation.
BACKGROUND AND PURPOSE Paroxysmal atrial fibrillation (PAF) is often difficult to detect in patients with acute ischemic stroke. We aimed to assess the predictive value of a prolonged QT interval corrected for heart rate (QTc) in PAF detection after acute ischemic stroke. METHODS We enrolled 972 patients with acute ischemic stroke consecutively extracted from our observational stroke registry...
متن کاملVentricular fibrillation during electrical cardioversion of pre-excited atrial fibrillation.
The Wolff-Parkinson-White syndrome can rarely present with pre-excited atrial fibrillation. In this condition the short refractory period of the accessory pathway can lead to rapid atrioventricular conduction. There is then a danger that at high heart rates the irregular broad complex tachycardia that results can deteriorate into ventricular fibrillation. The initial management of patients pres...
متن کاملNew Parameters for Left Ventricular Function in Atrial Fibrillation: Based on the Relationship between RR Interval and Performance
This study was designed to obtain new parameters representing left ventricular (LV) function independent of irregular RR intervals in atrial fibrillation (AF). AF patients were divided into Normal (n=9) and LV Dysfunction (n=9) groups. The relations between LV outflow peak ejection velocity (Vpe) and preceding (RR-1) or prepreceding RR intervals (RR-2) were obtained using logarithmic equations,...
