References
- If the Upper Tracking Rate is set to 190 min-1 or higher, the atrial and ventricular Rate Limit is 227 min-1 (+ 17 min-1). Otherwise, the atrial and ventricular Rate Limit is 200 min-1 (+ 20 min-1).
- Tolerance for amplitudes from 0.5 V through 6.0 V is + 10%, and for 7.5 V is -20/+0%. Tolerances are based on 37C and 500Ω load. Amplitude is dermined 200 µs after the leading edge of the pace.
- Atrial modes only.
- Blanking for Paced AV (PAV) and Sensed AV (SAV) intervals; pacemaker-determined.
- Blanking for Ventricular Refractory Period; pacemaker-determined.
