Overview
Electrocardiogram is particularly useful for cardiac amyloidosis. Findings on electrocardiogram include a variety of findings.
Electrocardiogram
Electrocardiogram is particularly useful for cardiac amyloidosis. Findings on electrocardiogram include:
- Low voltage QRS complexes[1]: Low voltages are present due to infiltrative heart disease and the reduced electrical conduction through the cardiac muscle.
- 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.
- First-degree AV block
- Second-degree AV block
- Third-degree AV block
