Overview
Hemochromatosis can lead to deposition of iron in the heart and damage its myocardial tissue as well as conduction tissue. It will cause cardiomyopathy and cardiac arrhythmia.
Electrocardiogram
EKG could be done to evaluate cardiac arrhythmia in patients of hemochromatosis.[1]
- However cardiac arrhythmia marginally increased in asymptomatic subjects with hemochromatosis.[2]
- The incidence of ventricular and supraventricular ectopy tends to be greater in the combined heterozygous form of hemochromatosis.
- 31% of patients have ST segment and T wave abnormalities and supraventricular arrhythmias.
- Some patients will have low-voltage QRS complexes, which is a suggestive feature of iron infiltration and impaired electrical conduction in the cardiac tissue.
