My caridologist retired

I found out today that my cardiologist retired and that's why i haven't been able to get an appointment with him. I called in and they told me that he refered me to someone else but it wast in my file so they have to call me back with the name of the dr.   Man I soo did not want to have to go thru a new dr. Seeing one is stressful enough let alone bringing another one upto speed. Ugh
