Key result
A new ventricular automatic capture algorithm accurately determined pacing thresholds with 96% and 94% success rates for commanded and ambulatory tests, respectively, compared to manual testing.

Does a new ventricular automatic capture algorithm accurately determine pacing thresholds compared to manual testing in patients undergoing pacemaker implant or replacement?
The new ventricular automatic capture algorithm accurately and safely determines pacing thresholds across various lead types and pacing configurations during acute testing.
Sperzel et al. (2005) conducted an observational in Pacemaker implant or replacement (n=53). Ventricular automatic capture algorithm (AutoThreshold) vs. Manual threshold test was evaluated on Success rate of commanded and ambulatory AutoThreshold tests. A new ventricular automatic capture algorithm accurately determined pacing thresholds with 96% and 94% success rates for commanded and ambulatory tests, respectively, compared to manual testing.
