May support echocardiographic differentiation of amyloidosis from hypertrophic cardiomyopathy; hypothesis-generating and requires prospective validation.
Do specific electrocardiographic and echocardiographic features differentiate cardiac amyloidosis from hypertrophic cardiomyopathy?
Echocardiographic and electrocardiographic features, specifically myocardial appearance, valve thickness, LV mass, and systolic anterior motion of the mitral valve, can reliably differentiate cardiac amyloidosis from hypertrophic cardiomyopathy.
Eriksson et al. (1987) studied this question.
