Comparing the catheter delivery system and the stylet delivery system for ventricular lead placement in pacemaker implantation-The CATS delivery system randomized controlled trial.

This will be the first clinical trial to compare the efficacy and safety of the catheter delivery system and the stylet delivery system during the implantation of the ventricular lead in pacemaker implantation. Our findings are expected to improve the lead implantation procedure by providing information about which delivery system to choose in which situation.
