Electrophysiology of T-wave alternans: mechanisms and pharmacologic influences.
Verrier RL, Malik M. Verrier RL, et al. J Electrocardiol. 2013 Nov-Dec;46(6):580-4. doi: 10.1016/j.jelectrocard.2013.07.003. Epub 2013 Aug 12. J Electrocardiol. 2013. PMID: 23948521 Review.
Extensive experimental evidence indicates a fundamental link between T-wave alternans (TWA) and arrhythmogenesis. Diverse physiologic and pathophysiologic influences alter TWA magnitude in parallel with their effects on vulnerability to ventricular tachyarrhy …
