Abstract :
Reports which describe sick sinus syndrome due to malignant lymphoma have been rare and only eight cases have been reported until now. This is a case of sick sinus syndrome and superior vena cava syndrome secondary to invasion of occult malignant lymphoma of the lung in a 60 years old male. There were no symptoms or signs of malignancy before the first presentation with sick sinus syndrome. Patient was treated with implantation of a permanent pacemaker. SA node involvement by lymphoma should be considered as an etiological factor when sick sinus syndrome of unknown cause is encountered.
