Key result
Permanent pacemaker implantation for metastatic tongue carcinoma-induced heart block precedes fatal haemoptysis at 5 days.
Why the study?
Secondary metastatic involvement of the heart commonly presents with arrhythmias, but complete heart blocks are very rare and require careful diagnostic assessment.
Population
28-year-old man with carcinoma of the tongue and complete heart block due to malignant cardiac infiltration
Comparison
Permanent pacemaker implantation

CHB may indicate cardiac metastasis in tongue carcinoma; hypothesis-generating case that extends known metastatic presentations.
Case Report (n=1)
Complete heart block is a rare but possible presentation of secondary metastatic infiltration of the heart, highlighting the need for careful ECG and multimodality imaging assessment in oncology patients.
Kumar et al. (2018) conducted a case report in Metastatic complete heart block (n=1). Permanent pacemaker implantation was evaluated on Clinical outcome. Permanent pacemaker implantation was performed for complete heart block due to metastatic tongue carcinoma, but the patient succumbed to massive haemoptysis 5 days post-implantation.
