Noninvasive Characterization of Myocardial Diseases With Hypertrophic Phenotypes Using Integrated ECG/Echocardiographic Indices.
BACKGROUND Indices reflecting the discordance between QRS complex voltages on ECG and left ventricular (LV) wall thickness or LV mass index on echocardiogram (echo) have enabled identification of cardiac amyloidosis (CA) among patients with hypertrophic hearts. However, this evidence comes from studies that have exclud...
