摘　　要：To the Editor:Cardiac amyloidosis(CA)is an infiltrative cardiomyopathy characterized by extracellular deposition of misfolded insoluble amyloid fibrils.^([1])Electrocardiography(ECG)is an essential diagnostic test characterized by low QRS voltages in CA,observed in 20–74%of patients.^([2])Cipriani et al^([3])reported that low QRS voltages could independently predict cardiovascular death.But the mechanisms underlying low QRS voltages in CA remain unclear.

关 键 词：AMYLOID PATIENTS death.
