    Abstract:

    We describe the fi rst case report of a patient with cardiac metastasis from squamous cell cancer of the lung that manifested as a symptomatic tachy-bradyarrhythmia suggestive of a sick sinus syndrome. This condition generally follows a silent course. We hypothesize that the arrhythmias were attributed to the nodular metastatic lesions directly and extensively invading the right atrium and other parts of the heart.

    Key words: Cardiac metastases, lung, sick sinus syndrome, squamous cell cancer.
