Non-arrhythmic mortality may attenuate the benefits of pacemaker therapy and make pacemaker implantation a less cost-effective choice in very old patients. We also observed an association between death and lower ejection fraction.
In this first part of the 2-part review of cardiac pacing, we explore the state-of-the-art: the basics of pacing physiology, pacing modes and indications, periprocedural management, complications, basic troubleshooting, perioperative management for nonpacemaker procedures, and cardiac magnetic resonance imaging (CMR) of patients with pacemakers.
1 paź 2016 · Despite the increasingly high rate of implantation of pacemakers (PMs) and implantable cardioverter defibrillators (ICDs) in elderly patients, data supporting their clinical and cost-effectiveness in this age stratum are ambiguous and contradictory.
7 sie 2023 · To facilitate the use and understanding of pacemakers, a standardized classification code has been developed. Most patients can be managed with one of three common modes (AAI, VVI, or DDD), with or without rate responsiveness.
1 gru 2019 · Pacemaker therapy seems a clinically effective therapeutic option to improve survival and to control bradyarrhythmia-related symptoms in very elderly patients. Kaplan-Meier estimates of time to...
There was a survival improvement of about 30% in patients with AAI pacing compared to VVI pacing, and AAI pacing also reduced the risk of either paroxysmal or permanent atrial fibrillation.
6 paź 2024 · Pacing Modes – Advantages and Disadvantages. MODES. AAI. atrial pacing and sensing; if no electrical impulse sensed then pacemaker will pace @ a pre-programmed rate; if electrical impulse sensed then pacing inhibited; VVI. ventricular pacing and sensing; if no electrical impulse sensed then pacemaker will pace @ a pre-programmed rate
