WebbThe rapid ventricular rate during atrial fibrillation is one of the main causes of the increased mortality observed in individuals with atrial fibrillation. Rate control implies that the ventricular rate is the treatment target. The aim is to slow ventricular rate as much as possible without provoking excessive bradycardia.

WebbFör 1 dag sedan · Leadless pacing is a rapidly growing field. Initially designed to provide right ventricular pacing for those who were contraindicated for conventional devices, the technology is growing to explore the potential benefit of avoiding long-term transvenous leads in any patient who requires pacing. In this review, we first examine the safety and ... WebbAfib stands for atrial fibrillation (AF), which is a type of arrhythmia, or abnormal heartbeat. Afib is caused by extremely fast and irregular beats from the upper chambers of the heart (usually more than 400 beats per minute). A normal, healthy heartbeat involves a regular contraction of the heart muscle. WebbIn the absence of stimulation, non-pacemaker cells (including the ventricular and atrial cells) have a relatively constant membrane potential; this is known as a resting potential. This resting phase (see cardiac action potential, phase 4) ends when an action potential reaches the cell. great university courses
