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 کاملAtrioventricular node modification in patients with chronic atrial fibrillation: role of morphology of RR interval variation.
BACKGROUND This study evaluates the role of RR interval distribution pattern as an outcome predictor of radiofrequency (RF) modification of atrioventricular (AV) node in chronic atrial fibrillation (AF) and attempts to elucidate the likely mechanism of rate control. METHODS AND RESULTS Sixty-five patients with chronic AF underwent AV node modification. The RR interval distribution pattern was...
متن کاملRR interval dynamics before atrial fibrillation in patients after coronary artery bypass graft surgery.
BACKGROUND Atrial fibrillation/flutter (AF) is a frequent complication of coronary artery bypass graft surgery (CABG) that leads to increased costs and morbidity. We hypothesized that heart rate variability (HRV), an indicator of cardiac sympathovagal balance, is altered before the onset of postoperative AF. Because nonlinear methods of HRV analysis provide information about heart rate dynamics...
متن کاملAtrial Fibrillation Detection Based on Poincaré plot of RR Intervals
Atrial fibrillation (AF) is one of the most common types of arrhythmia which significantly increases the risk factor of stroke – especially in elderly population. In this paper an algorithm is presented which is suitable for the effective detection of AF, by using merely heart rate data as input. The method is based on the processing of Poincaré plots constructed from the set of 30 RR intervals...
متن کاملmodel for generating RR intervals in atrial fibrillation and beyond
Background: Realistic modeling of cardiac inter-beat (RR) intervals is highly desirable for basic research in cardiac electrophysiology, clinical management of heart diseases, and developing signal processing tools for ECG analysis. Methods: We present an open source computer model that is capable to generate realistic time series of RR intervals in both physiologic and pathologic conditions. D...
