Implication

May inform arrhythmia mechanisms; hypothesis-generating for channel-targeted therapies without clinical application yet.

Key Points

Review the biophysical properties and pathophysiological roles of mechanosensitive ion channels in mediating mechanical-to-electrical feedback within the heart ventricles.
Synthesized experimental and theoretical modeling literature addressing ventricular electromechanical coupling.
Evaluated beat-by-beat cardiac electrophysiology in response to mechanical stimuli.
Mechanosensitive ion channels enable the heart to convert mechanical deformations directly into electrical responses.
Theoretical and experimental models demonstrate that mechano-electric feedback significantly alters ventricular beat-by-beat function and contributes to cardiac pathophysiology.
