ABSTRACT
Vertigo due to primary cardiac disease, known as cardiogenic vertigo, has been rarely reported. We report one case showing recurrent vertigo episodes due to sick sinus syndrome. A 77-year-old female presented to our department because of long history of intermittent brief episodes of rotatory vertigo and non-vertiginous dizziness. She had no past medical history. There was no abnormal sign in neurological examination. Cardiac murmur, finally confirmed as grade 4 ejection systolic and grade 3 decrescendo diastolic murmurs, was found on physical examination. Brain magnetic resonance imaging and auditory evoked potential did not show any abnormal findings. She was consulted to a cardiologist for the evaluation of cardiac murmur. After the evaluation using electrocardiogram, echocardiography, and holter monitoring, she was diagnosed as sick sinus syndrome. After then, a ventricle ventricle inhibited (VVI) pacemaker was inserted. She did not complain of vertigo and dizziness for 3 months after the insertion of a VVI pacemaker. This case shows the need of auscultation for patients with recurrent vertigo episodes although there is rare cardiogenic vertigo.

MELAS syndrome is typically a multisystemic disorder. We report one case of MELAS showing both maternally transmitted type II diabetes mellitus (DM) and deafness. A 41-year-old woman was admitted because of severe headache and vomiting. She developed type II DM at age 26 and was followed by bilateral sensorineural type hearing loss at age 37. Family history revealed that her mother and two sisters suffered from similar disorders. MELAS with A3243G point mutation was confirmed in the patient and her daughter.
