I have been waiting for weeks to see a cardiologist (holter monitor results were not good), they called today to say they have to reschedule this Friday's appt. They could see me on October 3rd now. What?! It's my heart we are talking about not a hair appt that can wait. I found another clinic right away and I have an appt on Monday.
