Follow up to emergency procedure and new medication. Very informative and found there is another possible procedure for AFIB but the wait to get this is three months. Like the idea of another possible procedure.

My initial visit with Dr. Krishnan was fantastic. He was very knowledgeable in explaining everything that was happening with my AFIB and the Best Practices” for treatment. He offered several options and made sure I understood how they would all play out. There was a lot to consider, however even before I arrived home my decision was made and I immediately called his office to move forward with scheduling. I’m looking forward to a successful resolution of my issue.

I have been a patient of Dr. Krishnan since 2018 when I was diagnosed with AFIB. He was at Rush at that time and I followed him to the Midwest Cardiovascular Institute. He had performed a successful cardiac ablation in 2019. He is extremely knowledgeable, and explains everything so that the patient completely understands the situation. Very friendly and answers all questions and concerns. I have recommended him to others because of his we’ll he treats his patients.
