Key result
Optical mapping of 763 wave break episodes during ventricular fibrillation in swine right ventricles revealed they are produced by head-tail interactions and filament break.
Surface patterns of wave break during sustained ventricular fibrillation in swine right ventricles are produced by two fundamental mechanisms: head-tail interaction between waves and filament break.

In vitro swine RV data suggest unified wave break mechanisms in VF; leaves open in vivo human validation before any clinical relevance.
Lee et al. (2001) studied Ventricular fibrillation (n=6). Optical mapping and single cell transmembrane potential recording was evaluated on Patterns of wave break. Optical mapping of 763 wave break episodes during ventricular fibrillation in swine right ventricles revealed they are produced by head-tail interactions and filament break.
