Am surprised the article did not mention two genes that are known to link catecholamines (adrenaline et al) and ventricular tachycardia. One gene is for the cardiac ryanodine receptor, and the other is for the CAS2Q gene.

An obvious conclusion is that the threshold for exercise-induced VT is variable across individuals.

There are lots of other genes linked to sudden death during exercise. Examples: long QT genes, hypertrophic cardiomyopathy genes. It's not hard to understand why they are rare. :-)
