Deposition of abnormal substances in patients with infiltrative cardiomyopathies can either increase the LV wall thickness or cause chamber enlargement with the attendant wall thinning and systolic impairment. Increased wall thickness is not necessarily indicative of myocyte hypertrophy; it may be a reflection of the accumulation of intracellular or interstitial substances. Low QRS voltage—despite a “hypertrophic” appearance—is observed more often with interstitial accumulation more than with intracellular accumulation. [44]
