Running and the Heart 5
Figure 5. The relationship of channelopathy, cardiomyopathy, and coronary-artery pathology with the incidence of sudden cardiac death. Note that channelopathies and cardiomyopathies both predispose to irregular heartbeats (arrythmias), which can cause the heart to pump ineffectively. Coronary-artery pathology predisposes to “heart attacks” (when the heart does not get enough blood).
