Overview
Patients with pulmonary tuberculosis often have a normal EKG, but pericardial effusion may occur leading to EKG changes. Extra-pulmonary tuberculosis, such as tuberculous pericarditis, can show EKG changes.
Electrocardiogram
- Patients may get a pericardial effusion secondary to tuberculosis and this may present as as low voltage and tachycardia on an EKG.
- In patients who develop tuberculous pericarditis, the ECG may show non-specific ST segment and T-wave changes.[1][2]
- Characteristic EKG finding of acute pericarditis, PR-segment depression, and diffuse ST-segment elevation are found in only 9-11% of cases[3][2].
- The detection of a low QRS voltage and electrical alternans on EKG indicates a pericardial effusion and / or tamponade.
