Article Synopsis
- A new dual chamber leadless pacemaker system utilizes a temperature-based sensor to monitor heart rate response during exercise, focusing on its effectiveness in both the right ventricle and right atrium.
- An exercise test was conducted 6 weeks post-implant on eligible subjects to evaluate the pacing response of the ventricular and atrial devices, measuring if the rate increased proportionately with metabolic workload.
- Results showed that both the ventricular and atrial devices had mean rate-response slopes (0.93 and 0.91, respectively) within the acceptable range, indicating that the temperature-based sensor effectively adjusts pacing to meet increased metabolic demands.
Article Synopsis
- - The Aveir DR system is a new type of dual-chamber leadless pacemaker that features separate atrial and ventricular components capable of communicating wirelessly for synchronized heart pacing.
- - A study involving 399 patients showed that the success rates of implant-to-implant (i2i) communication between the atrial and ventricular pacemakers exceeded 90% at all tested intervals over six months.
- - Improvements in communication success were noted, particularly for patients with initial lower success rates, suggesting benefits from reprogramming and device stabilization over time.
Article Synopsis
- * This system uses two leadless devices that communicate with each other instead of traditional wires, which makes it unique in its design.
- * The paper provides an overview of the dual-chamber pacemaker implantation process, highlighting important steps to ensure safe and efficient procedures.
Background: A dual-chamber leadless pacemaker system has been designed for atrioventricular synchronous pacing using wireless, beat-to-beat, implant-to-implant (i2i) communication between distinct atrial and ventricular leadless pacemakers. The atrioventricular synchrony achieved across various ambulatory scenarios has yet to be systematically evaluated.
Methods: A prospective, single-arm, unblinded, multicenter, international clinical trial of the leadless pacemaker system was conducted in patients with a conventional dual-chamber pacing indication enrolled from February 2022 to March 2023.
Background: The first dual-chamber leadless pacemaker (DC-LP) system consists of 2 separate atrial and ventricular devices that communicate to maintain synchronous atrioventricular pacing and sensing. The initial safety and efficacy were previously reported.
Objective: The purpose of this study was to evaluate the chronic electrical performance of the DC-LP system.
