Had a pacemaker put in and it went very well and smoothly and was looked after very well by DR Behar
Dr Behar did a full cardiological review following a very low heart rate and arrythmia diagnosed during a pre-op for a minor surgery which was unable to progress. Dr Behar's initial check indicated no major concerns but to ensure nothing was missed and there were no underlying concerns a full assessment was performed. Dr Behar kept me informed throughout and provided me with a full and detailed explanation of all the results in writing and in person and answered all remaining questions I had. Excellent professional and personal care throughout and highly recommended.
I was very impressed and grateful for the calm efficiency from the moment I stepped into the Hospital. It was so very reassuring. I am 90 years and have bad arthritis, and was given a wheel chair immediately I arrived. I was taken to a quiet, calm efficient person who took my details. Then given a cup of coffee. Dr Behar saw me On Time and gave me 35 minutes of unhurried Medical information and advice. Fortunately it was all Good News ! My Blood Pressure has come down, and my heart does not need a pacemaker ! I am so impressed and grateful to Dr Behar and the Hospital. Mega Thanks !
Dr Behar was very professional and thorough in his examinations and arranged all the necessary tests quickly and efficiently to further investigate my condition.
Confident assessment and taking the necessary steps in order.
Helpful, everything explained clearly with a good action plan
The nurses and doctors were very attentive and looked after me really well.
It was great meeting you Jonathan thankyou foe explaining everything clearly. I trust that you will help me live my best life.
Seeing Dr Behar was a far more pleasant experience than it could have been. I was quite anxious when I saw the doctor but he put my mind at rest, he was warm and sympathetic and I would be very happy to recommend him to anyone who needs the services of a Cardiologist.
