Normal activation of the myocardium during sinus rhythm both in the septum and in the right and left ventricular free wall occurs mainly from apex to base and from endocardium to epicardium. [102] The ...
BARCELONA, SPAIN—Cardiac resynchronization therapy (CRT) using an algorithm designed to minimize unnecessary right ventricular pacing is not superior to conventional CRT in patients with systolic ...

Single-chamber ventricular leadless pacemakers do not support atrial pacing or consistent atrioventricular synchrony. A dual-chamber leadless pacemaker system consisting of two devices implanted ...
This ECG shows ventricular pacing. Note the pacer spike prior to each QRS complex, most apparent in leads V5 and V6. The P waves appear sinus in origin and have no association with the QRS complexes ...
