Why the study?
Do different components of defibrillation waveforms (peak current vs energy) differentially affect postshock contractile dysfunction in isolated cardiomyocytes?
Do different components of defibrillation waveforms (peak current vs energy) differentially affect postshock contractile dysfunction in isolated cardiomyocytes?
Peak current, rather than energy, appears to be the primary determinant of postshock contractile dysfunction in isolated cardiomyocytes.
Answers are grounded in this paper and cite their sources.
Peak current may drive postshock dysfunction more than energy; leaves open waveform optimization for clinical defibrillation.
