aNKX2-5 functions as a repressor of the sinoatrial node lineage gene program, thus limiting pacemaker activity to the sinus node and the atrioventricular node. NKX2-5作用作为窦房结后裔基因节目的镇压者,因而限制心脏起搏器活动到静脉窦结和房室结。[translate] ...
A pacemaker has control circuits contained in an enclosure and a lead containing an electrical conductor connected to an electrode for delivering electrical stimulation pulses to a heart. The stretching of a wall in the ventricle, corresponding to adequate filling of the ventricle in the heart, is...

There is no evidence that permanent pacemaker (PPM) therapy leads to a mortality benefit in patients with SND, but there can be clear improvements in symptoms and quality of life [4,5,6]. In contrast, patients with high-degree AVB have improved survival if treated with pacing therapy, when...
Although the early single-chamber ventricular pacemaker provided adequate bradycardia support, its nonphysiological nature was quickly recognized due to its adverse hemodynamic effects. The goal of physiological pacing is to provide a pacing strategy that mimics or provides a full return to normal ...
