Summary of device behavior at ERI in pacemakers by major manufacturer
| Brand | Behavior at ERI |
||
|---|---|---|---|
| Mode | Rate | Features disabled | |
| Medtronic∗ | VVI | Set rate (65 bpm) or programmed rate decrease (7%–10%) | Hysteresis Sleep function ventricular capture management Atrial and ventricular sensing assurance |
| Vitatron∗ | VVI | Set rate (65 bpm) or programmed rate decrease (10%–20%) or increased R-R interval (100 ms) | EGM/episode/diagnostic data collection Rate response Post-PVC response Flywheel mode EGM range PVC-synchronous Astim Tachycardia fallback rate AF prevention therapies Ventricular rate stabilization Therapy advisor |
| Boston Scientific† | No change at ERI; VVI at EOL | No change at ERI; 50 bpm at EOL | |
| Guidant‡ | VVI | Set rate (65 bpm) or programmed rate decrease (11%–20%) | Automatic capture Rate response |
| St. Jude§ | No change | Increased R-R interval (100 ms) | Rate sensor NIPS test AF suppression |
| Biotronik¶ | Single or dual chamber, depending on programmed mode | Programmed rate decrease (4.5%–11%) | Atrial pacing Rate adaptation Atrial and ventricular capture control Atrial overdrive pacing EGM recordings Rate hysteresis Night program Rate fading Statistics Home monitoring Ventricular pacing suppression |
| ELA Medical (MicroPort)‖ | VVI | Set rate (70 bpm) | Rate response Smoothing Rate hysteresis |
AF = atrial fibrillation; EGM = electrogram; EOL = end of life; ERI = elective replacement indicator; NIPS = noninvasive programmed stimulation; PVC = premature ventricular contraction.
