Triggering of nocturnal arrhythmias by sleep-disordered breathing events.

Nov 2009 OBJECTIVES: This study sought to evaluate respiratory disturbances as potential triggers for arrhythmia in patients with sleep-disordered breathing (SDB). BACKGROUND: SDB is associated with an increased risk of atrial fibrillation and nonsustained ... Read more...

Myocardial perfusion, function, and dyssynchrony in patients with heart failure: baseline results from the single-photon emission computed tomography imaging ancillary study of the Heart Failure and A Controlled Trial Investigating Outcomes of Exercise TraiNing (HF-ACTION) Trial.

29 Sep 2009 BACKGROUND: There are currently limited data on the relationships between resting perfusion abnormalities, left ventricular ejection fraction (LVEF), New York Heart Association (NYHA) functional class, and exercise capacity as defined by peak VO(2) ... Read more...

Specification of the cardiac conduction system by transcription factors.

23 Sep 2009 Diseases of the cardiovascular system that cause sudden cardiac deaths are often caused by lethal arrhythmias that originate from defects in the cardiac conduction system. Development of the cardiac conduction system is a complex biological process ... Read more...
