My entire conversation with the electrophysiologist lasted less than 10 minutes and no new care was provided or recommended. He looked at five-year-old test results from another clinic and drew a quick conclusion, then dismissed me I expected more from the top cardiology clinic in the country

Reviewed on Feb 15, 2024

The one think that was a disappointment was the fact that I did not see the doctor after my procedure was finished. I had questions that I wanted to ask him and was told to enter my questions in MyChart. That is a less than ideal way to communicate. I did put one of my questions In MyChart but, as expected. I received an answer 3 days later. I wanted an answer when my procedure was finished.
