Constant DI pacing suppresses cardiac alternans formation in numerical cable models
TL;DR: The results show that constant DI pacing significantly shifts the onset of both cardiac alternans and conduction blocks to higher pacing rates in comparison to pacing with constant cycle length, and reduces the propensity of spatially discordant alternans, a precursor of wavebreaks.

TL;DR: It was found that women with a history of control and consistent use ofMCs were the most likely users of FCs when MCs were not used, and women who reported, at study entry, having more control over MC use were more likely to use FCs during follow up.

TL;DR: The purpose of this study was to investigate the electrophysiological changes in the atrium resulting from long-term intermittent VNS therapy in the chronic myocardial infarction (MI) rat model, and concluded the MI decreased the APD and increased APD spatial dispersion.
