1. A medical device comprising:
therapy delivery circuitry having a plurality of capacitors and an output signal line, the therapy delivery circuitry configured to generate a composite pacing pulse comprising a plurality of sequential individual pulses by:
delivering a first pulse of the plurality of sequential individual pulses by coupling at least a first capacitor of the plurality of capacitors to the output signal line, and
delivering a second pulse of the plurality of sequential individual pulses by selectively coupling at least a second capacitor of the plurality of capacitors to the output signal line.
