ABSTRACT:
A method and apparatus for cardiac pacing, in which pacing pulses are provided at an increased rate in response to a detected rapid drop in heart rate. A rapid drop is detected in response to heart rate falling from a persistent rate above a first threshold rate to a stable rate below a second threshold rate. If spontaneous depolarizations are detected while pacing at the increased rate, pacing at the increased rate is terminated.
