Output Programming

Providing auto capture algorithms are functioning well, auto capture should be ON.

•Saves battery, some algorithms safer for dependent patients (e.g., BSc/BTK/SJM)
•Reconsider if pt is symptomatic *nocturnal testing

Output programming & longevity: About

Otherwise output margins should be at least double (2x) the threshold for RA & RV

•RA minimum 1.5V
•RV minimum 2.0V
•LV often only +0.5V safety

Longevity limitations

•Once pulse amplitude >2.5V, a voltage doubler may be utilized in the device circuitry & can have a larger effect on the battery lifespan

​

•Furthermore, when pulse amplitude is >5.0V, a voltage tripler may be utilized in the device circuity & can have an even further longevity impact.

​

Adjusting pulse widths may be a consideration to keep the output below the voltage doubler/tripler threshold
