Atrial pacing treatments
| AF treatments | AT treatments |
|---|---|
| For atrial fibrillation (AF), only 50 Hz atrial pacing can be programmed. Tiered atrial treatment can be programmed for atrial tachycardia (AT) with ramp, burst+, and 50 Hz pacing. Ramp and burst+ treatments can therefore only be delivered in AF if the device misclassifies the rhythms as AT. | |
