Before revision: An inappropriate rapid heart rate response to exercise may be seen, such as in the metabolic myopathy of McArdle disease (GSD-V), where the heart tries to compensate for the deficit of ATP in the muscle cells (metabolic fatigue) by increasing heart rate to maximize delivery of oxygen and blood borne fuels to the muscles for oxidative phosphorylation.
