I don't have a suggestion for a good one to try, but I will tell you, don't go to the Heart Place. They have absolutely no personalized care, they are terrible at explaining things, their staff is rude, and their patient load is ridiculous. I've been dealing with them because they are the only office with an electrophysiologist anywhere near me, but if I had a choice, it certainly wouldn't be them.
I heard that there is a group that operates out of Harris Methodist (I think?) in Fort Worth. Google them and give them a try maybe? I wanted to, but again they don't have an electrophysiologist on staff (and I have an arrhythmia that requires specialized care).
Good luck!
