Europace, 2000 Aims Drug-induced increase in QT dispersion has been associated with increased risk of ventricular proarrhythmia. The aim of the present study was to compare QT dispersion during atrial fibrillation and sinus rhythm in the same patients at normal and ...

A phenomenology model of normal sinus rhythm in healthy humans
IEEE Transactions on Biomedical Engineering, 2002The fractal component in the daytime healthy heartbeat interval data is studied from the perspective of cascade in fluid turbulence. Based on the electrophysiology of the heart muscle cell, a bounded random cascade model is assumed and the scaling property of the model is derived.

Anticoagulation in patients with heart failure and normal sinus rhythm
American Journal of Health-System Pharmacy, 2009The evidence evaluating the risk of thrombosis and the efficacy and risk of anticoagulation in patients with systolic heart failure (HF) and normal sinus rhythm is reviewed.Although a subject of investigation for over 50 years, use of anticoagulation in patients with HF remains an area of controversy and clinical debate.

Digitalis tolerance during atrial fibrillation and normal sinus rhythm
The American Journal of Cardiology, 1967Abstract In each of 9 normal dogs the toxic dose of acetylstrophanthidin was determined on three separate occasions during normal sinus rhythm and atrial fibrillation. During atrial fibrillation the mean toxic dose was 10 to 30 per cent (average 21%) greater than that recorded in the same animal during normal sinus rhythm.

Hemodynamics in atrial flutter with spontaneous reversion to normal sinus rhythm
American Heart Journal, 1957Abstract During cardiac catheterization of a 31-year-old woman with mitral stenosis, the development of atrial flutter and subsequent spontaneous reversion to normal sinus rhythm provided an opportunity to study the hemodynamic effects of the arrhythmia under ideally controlled conditions. The ventricular rate remained constant; no cardiac drugs were

Normal Sinus Rhythm–Sinus Bradycardia is Common in Young Children Post-extracardiac Fontan
Pediatric Cardiology, 2016We hypothesized that normal sinus rhythm-sinus bradycardia is common in young children following extracardiac Fontan. After excluding patients with sinus pauses, junctional rhythm, tachy-brady syndrome, frequent ectopics, or ectopic atrial rhythm, we found an ambulatory 24-h Holter monitor average heart rate of 78 ± 12 beats per minute (bpm) in 33 post-

Normal sinus rhythm in advanced mitral valve disease.
Archives of internal medicine, 1969Sixty-four patients with rheumatic mitral valve disease who had cardiac catheterization were studied with respect to rhythm, cardiac index, mitral valve gradient, pulmonary artery pressure, and age. They were divided into three groups: (1) moderately elevated pulmonary pressure and normal pulmonary vascular resistance, (2) high pulmonary pressure and ...

Abstract 25: Abnormalities within Normal Sinus Rhythm
Circulation: Cardiovascular Quality and Outcomes, 2019Trained cardiologists detect atrial fibrillation by visual interpretation of certain segments of electrocardiogram (EKG) lines known as the QRS complex. Similarly, available EKG-software also evaluates anomalies in the signals from the EKG-leads that produce the traces/lines in order to flag for atrial fibrillation.

Turbulence analogy in normal sinus rhythm of healthy humans
Computers in Cardiology 2000. Vol.27 (Cat. 00CH37163), 2002The complex dynamics of the autonomic nervous system manifests in the random fluctuation of the sinus rhythm. Recent results on multiple scaling and multifractal in HRV indicate intricate details beyond the second order statistics (such as the power spectrum) of the interbeat interval data (RRi).
