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-

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.

Normal sinus rhythm without the normal atrial kick
Heart Rhythm, 2005Atrial fibrillation (AF) affects more than six million people in the United States alone. It is associated with palpitations, reduced exercise tolerance, and dyspnea. Hemodynamic impairment results from loss of synchronous atrial contraction and rapid, irregular ventricular rates. Thromboembolism and stroke are serious complications.

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).

Inappropriate ICD discharges due to “triple counting” during normal sinus rhythm
Journal of Interventional Cardiac Electrophysiology, 2007To describe the clinical course of a patient with multiple ICD shocks in the setting of advanced renal failure and hyperkalemia.The patient was brought to the Electrophysiology Laboratory where the ICD was interrogated.The patient was found to be hyperkalemic (serum potassium 7.6 mg/dl).

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

Coexisting Normal Sinus Rhythm and Atrial Fibrillation 18 Years after Heart Transplant
Journal of Cardiac Surgery, 2008Atrial fibrillation is an important cardiogenic cause of embolic phenomenon to the brain leading to stroke and long-term disability. Recognition of atrial fibrillation is of cardinal importance in the workup of stroke and transient ischemic attack (to prevent future strokes) by the timely institution of anticoagulation therapy.

Hyperkalemia-induced conversion of permanent atrial fibrillation to normal sinus rhythm
Journal of Cardiovascular Medicine, 2011The electrocardiographic manifestations of hyperkalemia have been well described. We report the case of a patient with permanent atrial fibrillation for 13 months, who converted to normal sinus rhythm after treatment for hyperkalemia. This is the first case of hyperkalemia-induced conversion of permanent atrial fibrillation to sinus rhythm with a well ...

[Supraventricular paroxysmal tachycardias with normal electrocardiogram in sinus rhythm].
Archivos del Instituto de Cardiologia de Mexico, 1984Paroxysmal supraventricular tachycardia (SVT) was studied in 46 patients with normal electrocardiogram (ECG) during sinus rhythm (SR), All of them had had at least one SVT crisis. They all complained of palpitations starting and ending abruptly, and of more than one hour duration.
