Great doctor. Was very helpful and addressed all my concerns
This care team is by far, the best team I have ever worked with.
Dr Konstantinidis is an EXCELLENT Doctor with great bedside manner and outstanding professionalism. Thank you Doctor for being the best.
Like a gladiator and professional
Hes' great!!!!!
You are the best in your field Thank you
Dr. K was very professional and very kind. He answered all my questions and concerns. I feel that I will be well taken care of before, during, and after my procedure.
Dr. K is great. He listens and he knows how to explain things simply.
Dr. K was very concise and clear in explaining my condition and what care was needed.
Dr K saved me, that's what I will say. Persistent Afib after a failed ablation in 2024 (at another hospital) and I no longer have to take Amarodione to keep things in check. I will be forever grateful. He is kind, involved me in every step and for now, I am Afib and Atrial Flutter free and have been for over 3 months. My last one lasted 2 days, so many Cardioverts, I can't count them. He is very thorough and explains things in a way I can understand. Doesn't use his medical jargon to impress me, just down to earth and totally understanding. I can't say enough. If you need a great Afib Dr, he's the one!
Dr K was attentive and listened. I would recommend him.
I feel he is very courteous and competent
Just wish he would be closer to me instead of being so far away!
Great caring Doctor, listens and cares about your condition. Love him
He didn't appear. My contact was with some assistants'whuch was a little disconcerting. However, they appeared to be very capable.
I met with him last year and I'm still the same opinion of how how his bedside manner is. Just wonderful. He's a good, decent man. He tells me what I want to know and doesn't pull any punches. I really enjoy working with the doctor
Dr. Konstantinidis is very professional and knowledgeable but at the same time extremely personable. He talked about our previous visit some 2-3 years ago, he knew my history and addressed current questions with all of my background in mind. His cordial approach and gentle manners made my wife and I feel very relaxed. He just knows what to do and how to do it so provide a bond between patient and doctor.
He is very courteous and friendly and treated me with respect. Explained everything to me and took the time to make me feel comfortable. He answered all of my questions that I had at that time. I am grateful to have finally found a dr. with his kind of personality knowledge to help me understand my situation.
Dr. Was very through n informative about my heart. Would trust him if I ever needed anything done. Would Highly recommend him.

Very professional .listens to your concerns. Very knowledgeable & when you leave his office you have a game plan in place that you understand. Highly recommended.
I really appreciated just taking the time to explain things to me and he's one of the best doctors I have dealt with
A true professional who listens to you, answers your questions in a non-rushed manner, and make sure you're involved and understand the next-steps.
Great doctor answers questions and asks very pertinent questions
Dr. K did a great job with my pacemaker replacement. I would not hesitate to have family and friends go to him if needed.
Respectful, informative, and caring. Detailed and explaining results of testing ¿ also how testing results, and past history, relate to my health future.
I really like him. He is very easy to talk to and seems patient and kind.
Dr K is so much more helpful than any Dr's at IHC. He made me a part of the decision the whole way through. I have seen him more than I ever saw the IHC Dr. No comparison. U Of U you have my vote.
kept explanation in terms I could understand.
Dr K was the first Dr to help me understand what was happening and explained exactly what he was seeing and the options available!
He was very clear and simpl to understand and listened. He was not intimidating but very kind and straight forward. He didn't waste my time.
His knowledge and expertise are amazing and I really appreciate the friendship and concern he shows in my treatment & overall health. I would recommend him to all family and friends who need his guidance and help !
Dr. K is a great Doctor. I only wish he would of explain things a little more. I trust he will keep in touch with me so I know what is going on with my heart .
i DID NOT SEE Dr. K. Saw the pacemaker technician
The visit went poorly.
Dr. Konstantinidis is a great listener and he takes time to answer questions. I really like the way he explained things and then allowed me to have a say in my own healthcare. That meant a lot ti me! I also appreciate the way he made time for me in his busy schedule!! What great service he and his team provided!! Thank you so much!!
Dr.Klitos, took all the time needed to answer all my concerns and questions. I experienced a very relaxed office visit with Dr. Konstantinidis.
This man was kind but very professional and made us feel safe
He is courteous. He answered all my questions and listened to my concerns. I am looking forward to moving forward with my A-fib.
He was very thorough and it was a virtual visit. I wasn't sure what he could do without listening to my heart. He looked at test results and asked me questions to where he could suggest a treatment plan.
Dr. K has a comprehensive understanding of my personal situation. He has proven to me that, regardless of condition, he will and CAN do everything and anything to improve and sustain me as a person living with ideopathic cardiomyopathy. Dr Konstantinidis is there, backed by a great team of professionals, to make my life improve and to allow me to have the highest quality of life possible.
Dr. K and his team are awesome
He did an excellent job.
Caring, wants you to get all the care you need.

Excellent care was given to me by everyone in this office.
VERY VERY NICE

Dr K is the best of the best. I highly recommend him. He is personable and a great Electrophysiologist!
Dr K listens very carefully and speaks very thoughtfully and with lots of consideration. He is knowledgeable and seems guidelines based, which I think is so important. Exemplary care, I think.
Dr. KÕs clear explanation of the surgical procedure provided me confidence in the outcome.
He is so personable! I really feel his sincerity in caring for me.
Dr. "K" is an exceptional physician. I pride myself on being one of the best fighter pilots to have represented our country with over 10,000 flight hours. Dr. "K" is the finest cardiologist I have ever met. He listens, provides options and when asked, gives you his personal opinion as to what he would do if he were you. When you have heart issues like I do, you want your treating physician to skilled and knowledgeable but most of all you want to know all of your options. I came away from my appointment with a clear understanding of my treatment plan. I felt that I was in control. If you need to see and electro physiologist, you want Dr "K" leading your treatment team.
Dr K is awesome. We had a good visit. He was attentive to my concerns. And we made a plan.
I cannot say his last name but Dr. K works! I would highly recommend him to anyone!
Yes I would. It took me 4 months to get this appointment and me previous issues are not showing up now.
Amazing doctor. Very knowledgeable and caring.
Dr. K listens and cares about his patients. Would highly recommend him.
Delightful! Knowledgeable, down to earth, kind.
From the Office visit through the surgery Dr K was easy and precise to work with
