Recurrent Vertigo Episodes due to Sick Sinus Syndrome / 대한평형의학회지

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.
