Kim Zolciak Concerned After Heart Checkup in 'Don't Be Tardy' Sneak Peek: It's 'Pretty Serious'

A surprising update. Kim Zolciak meets with her heart doctor following surgery and learns that she needs to see a specialist in Don't Be Tardy's Wednesday, December 14, episode, as revealed in Us Weekly's exclusive sneak peek.

The Bravo unscripted series' preview clip shows Zolciak getting a checkup with heart surgeon Dr. Babaliaros, who operated on the star six months prior. 

Doctors realized that the Real Housewives of Atlanta alum had a heart condition after she suffered a mini stroke in September 2015, and she underwent surgery in October 2015.

"I wonder how everything looks," Zolciak, 38, tells husband Kroy Biermann. She adds to the camera, "Dr. Babaliaros is the doctor that put the device in my heart six months ago. He's kind of been getting me through this process, so hopefully today I'll have some kind of answer."

The surgeon tells Zolciak, "Just wanted to give you some news on your ultrasound. Things look great, but I did see a small abnormality on your EKG. It's probably going to turn out to be OK, but I would like to refer you to an electrophysiologist that works on the electrical aspect of the heart."

Zolciak is startled by this news and says to the camera, "I've never had an abnormal EKG ever — even right after my stroke, my EKG was perfect. So that's insane to me that my EKG now is not normal. That's pretty serious."

Watch the clip above. Don't Be Tardy airs on Bravo Wednesdays at 10 p.m. ET.
