Why the study?
Does chronic physical training increase atrial and ventricular refractoriness in isolated rabbit hearts?
Does chronic physical training increase atrial and ventricular refractoriness in isolated rabbit hearts?
Chronic physical training induces intrinsic electrophysiological modifications that increase ventricular refractoriness and electrical stability in isolated rabbit hearts, potentially protecting against reentrant arrhythmias.
