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. Conduction and rhythm disturbances are common in cardiac amyloidosis, however direct infiltration of the specialized conduction tissue of the heart by the amyloid does not account for the majority of these disturbances.
Electrocardiogram
Electrocardiographic findings in cardiac amyloidosis incluse:[1][2][3]
- Low voltage complexes
- Pseudo-infarct pattern (poor R wave progression)
- Left ventricular hypertrophy pattern
- Higher degree AV blocks
- AV nodal slowing
- Arrhythmias such as
Lack of variability in heart rate due to autonomic dysfunction can be found on Holter monitoring and also it is an important predictor of 1-year mortality.[4]
