Electrocardiogram (ECG)1-3

Transthyretin Amyloid Cardiomyopathy   >   Raising Suspicion of ATTR-CM   >   Cardiac Assessments
  • Discordance between LV wall thickness and QRS voltage
  • Pseudoinfarct patterns in up to 70% of cases
  • Conduction disease
  • Atrioventricular block in up to 22% of cases

Low QRS Voltage Is Not Always Present

  • Prevalence in ATTR-CM (20%)
  • Prevalence in AL amyloidosis (60%)

ECG showing low voltage throughout, pseudoinfarcts in
the anterior and inferior leads, and poor R-wave progression.3
