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.

A child with cardiogenic shock and supraventricular tachycardia presenting in normal sinus rhythm
Pediatric Emergency Care, 1996We report a case of an infant who presented in profound cardiovascular collapse with a normal sinus rhythm initially. A diagnosis of supraventricular tachycardia (SVT) was established only after hemodynamic stabilization. The possibility of SVT being masked because of severe metabolic derangements and/or painful therapeutic procedures should be kept in

To Be or Not To Be in Normal Sinus Rhythm: What Do We Really Know?
Annals of Internal Medicine, 2004Two papers in this issue raise questions about managing atrial fibrillation: Does rhythm control have any role in treating patients similar to the Atrial Fibrillation Follow-up Investigation of Rhy...

Hemodynamics before and after conversion of atrial fibrillation to normal sinus rhythm in horses.
Journal of the American Veterinary Medical Association, 1984Hemodynamic measurements were obtained from 17 horses with atrial fibrillation or flutter. Eight horses had atrial fibrillation of unknown duration. In 7 horses, atrial fibrillation developed during anesthesia.

This paper intends to identify a method to distinguish between ECG signals from the Normal Sinus Rhythm (NSR) database and those from the Arrhythmia database. It also attempts to distinguish between NSR and Atrial Fibrillation (Afib). The ECG samples were taken from the database of MIT-BIH.

Abstract 1. 1. The electrocardiographic findings of myxedema heart have been reviewed. These are, briefly: (a) low voltage of all complexes, (b) flattening and inversion of the T waves, and (c) reversion toward normal on thyroid therapy. 2. 2.

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).
