Cardiac pacing and defibrillation studies

This cluster of papers focuses on the use of Cardiac Resynchronization Therapy (CRT) in the management of heart failure, particularly in patients with left ventricular dysfunction and ventricular arrhythmias. The cluster covers topics such as the use of implantable cardioverter-defibrillators, echocardiography-guided lead placement, remote monitoring, and the impact of CRT on dyssynchrony and sudden cardiac death.
