Overview

In a few patients with hepatocellular carcinoma, metastasis to right ventricle may cause the ECG to show low voltage in limb leads, diffuse T-wave inversion and prolongation of the QT interval.

ECG Findings in Hepatocellular Carcinoma

Abnormalities of cardiac electrophysiology may be noted in cases of hepatocellular carcinoma. Low voltage complexes in the limb leads may also be noticed in patients due to right ventricular metastasis. An ECG may be helpful in the diagnosis of metastatic hepatocellular carcinoma into the right ventricle.

Low voltage in limb leads and diffuse T-wave inversion
  • Findings on an ECG suggestive of metastasis of hepatocellular carcinoma into the right ventricle include low voltage in limb leads and diffuse T-wave inversion[1]
QT interval prolongation
Attenuation of ECG voltage
