Overview
Patients with pulmonary tuberculosis usually have a normal EKG, but pericardial effusion might develop and lead to EKG changes. Extra-pulmonary tuberculosis, such as tuberculous pericarditis, can present with EKG changes.
Electrocardiogram
- Patients can develop a pericardial effusion secondary to tuberculosis and this might be manifested as low voltage and tachycardia on an EKG.
- In in cases of tuberculous pericarditis the ECG may show non-specific ST-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 presence of a low QRS voltage and electrical alternans suggests the presence of a pericardial effusion and / or tamponade.
