Superior Vena Cava Rhythm Masquerading as Normal Sinus Rhythm
Journal of Cardiovascular Electrophysiology, 2004We report the case of a patient with persistent cardiac rhythm originating from the superior vena cava (3 cm above the vena cava‐atrial junction). It was detected by noncontact balloon mapping before induction of tachycardia and confirmed by conventional contact mapping with image studies.

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.

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 ...

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.

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).
