For the past few weeks, I’ve made Wednesday “Article Review” day. I’ll still post reviews that I deem pertinent on other days, but the goal is to post one each Wednesday at a minimum.
The Hubmed page for today’s article is here: Unpinning of a Rotating Wave in Cardiac Muscle by an Electric Field by Alain [...]

Another long title. The whole thing is below.
Hubmed Page: Role of Cardiac ATP-Regulated Potassium Channels in Differential Responses of Endocardial and Epicardial Cells to Ischemia
This 8-page article quantifies in great detail the ATP sensitivity of ATP-regulated potassium channels, often referred to as IK(ATP). As the article shows by many references, it’s known that the epicardium [...]

I had to cut the title a bit short, because it’s a long one.
Hubmed Page: What can nonlinear dynamics teach us about the development of ventricular tachycardia/ventricular fibrillation?
This short article (3 pages) describes in a very readable way how nonlinear dynamics may be applied to understand beat-to-beat alternans of action potential duration and amplitude. While [...]

Hubmed Page: Reentry in heterogeneous cardiac tissue described by the Luo-Rudy ventricular action potential model (with abstract)
The primary focus of this article is the effect of a gradient of action potential duration (APD) on spiral wave dynamics. The authors ran several simulations of a spiral wave using the Luo-Rudy I ionic model, and tracked [...]

Hubmed Page: A Chilling Tale
This is an article about a clinical case of a man who went to an emergency room for diarrhea, and ended up having a heart attack. It goes on to analyze the odd ECG recordings he produced, describe how hypothermia was induced to minimize damage, and elucidate the origin of [...]
