Propranolol in mitral stenosis during sinus rhythm

American Heart Journal, 1977
Patients with early symptomatic mitral stenosis usually suffer from pulmonary congestion on the basis of left atrial and pulmonary venous hypertension. They are often in sinus rhythm, and cardiac output is usually well maintained. Symptoms occur most often when heart rate, cardiac output, or both are increased.

Does Sinus Rhythm Beget Sinus Rhythm? Effects of Prompt Cardioversion on the Frequency and Persistence of Recurrent Atrial Fibrillation

Cardiac Electrophysiology Review, 2003
Recent clinical and experimental studies have demonstrated that atrial fibrillation (AF) alters the electrical and mechanical remodeling of the atrium, which subsequently promote the maintenance and recurrence of AF. If atrial remodeling can be prevented with prompt and repeated cardioversion, the likelihood of AF recurrence may be reduced.

Restoration of Sinus Rhythm: Pharmacological or Electrical?

1998
Atrial fibrillation (AF) is the most commonly occurring cardiac arrhythmia; nonetheless, management strategies for its control are far from satisfactory. Most patients experience palpitations, but dyspnea, lightheadedness and fatigue are not uncommon. In some patients even totally asymptomatic AF may be responsible for thromboembolic events, especially

Coronary sinus rhythm and umbilical vein catheterization

The Journal of Pediatrics, 1973
The arterial blood supply of the spinal cord below the second thoracic segment arises from the intercostal and lumbar branches of the aorta. Complete transection of the spinal cord may result from ischemic necrosis due to interruption of the blood supply to the thoracic segment of the spinal cord.

Clinical Trials of Pacing for Maintenance of Sinus Rhythm

Journal of Interventional Cardiac Electrophysiology, 2004
Several prospective randomized clinical trials have demonstrated that atrial-based pacing prevents the development of paroxysmal and persistent atrial fibrillation (AF) in patients with symptomatic bradycardia as the indication for a pacemaker. The greatest benefit appears to be in patients with sinus node dysfunction as the primary indication for ...

Atrial fibrillation: maintaining the sinus rhythm

1996
Atrial fibrillation is the most common sustained arrhythmia seen in clinical practice. In the Framingham study, the incidence is estimated to be 2% to 4% of the general population above 65 years of age [1]. The incidence is even higher in patients with underlying heart disease [2].
