I Need The Best Male Cardiologist Within A 15 Mile

I need the best male cardiologist within a 15 mile radius of Brentwood , ? My friend spent 4 hours at Southside and upon leaving he had no referral for a cardiologist , his blood work , I dont know if the did a FBC or a CBC but he neeeds an appointment to narrow down the cause of these slighlty almost panic attack heart palpitations. I really appreaciate any direction regarding this matter, My friend is really too nervous and he is just starting to admit it.
