A new AI algorithm is nearly twice as accurate as physicians at forecasting a sudden cardiac arrest in people with ...

The past 12 months mark a milestone year for the discipline of sports and exercise cardiology.We have seen the publication of two major guideline documents for athletes: the 2025 American Heart Associ ...

This design permitted the heart to contract freely during action potential recordings except for the 1-cm 2 area within the mapping field, while the electrophysiological side effects associated with ...

A digital simulation of a two-dimensional cardiac slice has been performed. It is stimulated at the center and an action potential propagates outward. An anisotropic bidomain model is used in which ...

Results Application of the 2010 ESC criteria, compared with the 2005 criteria, reduced the number of participants with abnormal ECG findings from 83/508 (16.3%) to 49/508 (9.6%). The reduction in the ...

Wearable technology has moved beyond fitness trackers and has become a critical tool in modern healthcare, especially in cardiac care. In particular, wearable electrocardiogram (ECG) devices provide ...

A live-action adaptation of Makoto Shinkai's criminally underappreciated movie 5 Centimeters per Second is in the works – and its new trailer might break your heart all over again.

Innovation in cardiac diagnostics Sunfox’s flagship product is Spandan, a portable, AI-powered ECG device designed to overcome the barriers of access and affordability in cardiac care.

Two prevailing hypotheses have been put forth to explain the pathogenesis of cardiac alternans. The first posits that alternans is a membrane voltage or action potential (AP)–driven phenomenon. Under ...

Cardiac Action Potential The characteristic voltage trajectory of membrane potential with time in cardiac cells is determined by the sequential activation, inactivation and deactivation of a ...

Heartbeat signals are useful to disease prediction, sub-health diagnosis, fatigue warning, and even emotion estimation. There is a compelling need for contactless, easy-to-deploy, and long-term ...
