Overview
The combination of low voltage electrocardiographic pattern and increased thickness of the left ventricular posterior wall and interventricular septum on echocardiogram is highly specific for cardiac amyloidosis.
Electrocardiogram
Electrocardiographic findings in cardiac amyloidosis incluse:[1][2][3]
- Low voltage complexes
- Pseudo-infarct pattern
- Left ventricular hypertrophy pattern
- Higher degree AV blocks
- AV nodal slowing
- Arrhythmias such as
