Overview
An ECG may be helpful in the diagnosis of secondary amyloidosis.
Electrocardiogram
- An ECG may be helpful in the diagnosis of secondary amyloidosis. Findings on an ECG suggestive of cardiac involvement include:[1]
- Voltage is lower than 5 mm in all limb leads.
- Other possible findings include:
- Left ventricular hypertrophy[2]
- Right ventricular hypertrophy[2]
- Left atrial abnormalities
- Pathological Q waves[2]
- Atrioventricular block: AV block occur due to deposition of amyloid fibrils in the conduction tissue.
- Cardiac involvement rarely occurs in the secondary amyloidosis and other possible cause should be ruled out first.[3]
