We here for the first time describe a patient with false-positive cardiac 13N-ammonium positron emission tomography test because of a LBBB. Underlying coronary artery disease could be ruled out by angiography. The clinical significance of a LBBB is discussed.N-ammonium positron emission tomography test because of a LBBB.
