Medtronic's letter to clinicians contains more details on the issue: <a href="https://www.medtronic.com/us-en/healthcare-professionals/products/product-performance/dual-chamber-pacemaker-recall.html" rel="nofollow">https://www.medtronic.com/us-en/healthcare-professionals/pro...</a><p>"For this error to occur, a unique combination of events must take place while the device is processing an atrial-sensed event. If this error occurs, the device will be unable to provide pacing until a ventricular-sensed event (VS) is detected. Once a VS is detected, normal pacing functionality is restored immediately. If a VS is not detected, the device will withhold both atrial and ventricular pacing. In addition, until a VS is detected, the device will be unable to initiate a session with a programmer, initiate a session with a CareLink™ remote monitor, or respond to a magnet. "
