Sinus Rhythm and Chronic Atrial Fibrillation
Methods and Results: Atria versus ventricles have lower IK1, resulting in more depolarized resting membrane potential ( 7 mV). We used higher Ito,fast density in atrium, removed Ito,slow, and included an atrial-specific IKur. INCX and INaK densities were reduced in atrial versus ventricular myocytes according to experimental results. SERCA function was altered to reproduce human atrial myocyte ...
متن کاملAtrial fibrillation. Reversion to normal sinus rhythm.
Auricular, or atrial fibrillation, is one of the most common cardiac arrhythmias. The mechanism of diagnosis will not be considered here, but rather the clinical criteria for attempted reversion to normal sinus rhythm. This report is concerned with the chronic type associated with severe organic heart or vascular disease, and in those persons previously considered bad risks. The treatment of at...
متن کاملAtrial fibrillation and congestive heart failure: a cost analysis of rhythm-control vs. rate-control strategies.
BACKGROUND Atrial fibrillation (AF) is common in patients with heart failure. Rhythm- and rate-control strategies are associated with similar efficacy outcomes. We compared the economic impact of the 2 treatment strategies in patients with AF and heart failure from the province of Québec, Canada. METHODS In a substudy of the Atrial Fibrillation and Congestive Heart Failure trial, health care ...
متن کاملA new tissue doppler index in predicting future atrial fibrillation in patients with heart failure.
BACKGROUND Onset of atrial fibrillation (AF) in patients with heart failure (HF) is usually associated with a high occurrence of cardiovascular complications. E/(E'×S') ratio (E=early diastolic transmitral velocity, E'=early mitral annular diastolic velocity and S'=systolic mitral annulus velocity) has been shown to reflect left ventricular filling pressure. OBJECTIVE We investigate whether E...
