Supports tuned waveforms for high-DFT patients; extends RCT evidence on individualized ICD programming.
Does a tuned biphasic waveform reduce defibrillation thresholds compared to standard waveforms in patients undergoing ICD testing?
Tuned optimal pulse durations in ICDs can lower defibrillation thresholds in patients with high baseline DFTs, offering greater programming flexibility.
