Sensing And Pacing Thresholds

Pacemaker Mediated Tachycardia Icd

For manual sensing threshold determination, the device should first be re-programmed below the intrinsic rate to assess sensing. In single-chamber devices, ventricular sensing thresholds may be determined by then decreasing sensitivity i.e., increasing the millivolt values in the VVI mode to determine at what value Figure 11.10. Stored atrial top and ventricular bottom electrograms from a pacemaker with automated electrogram capture triggered by a high ventricular rate. The patient experienced...
