Prognostic value of fluorine-18 fluoro-2-deoxyglucose positron emission computed tomography in patients with unexplained atrioventricular block

Patients with high-degree AVB and abnormal myocardial 18-FDG PET uptake have more adverse cardiac events and worse outcomes. Early screening for myocardial inflammation and appropriate treatment may prevent these complications. Tuberculosis may be an important cause of unexplained AVB, apart from sarcoidosis, in developing countries such as India.
