I was diagnosed with hypertension following a routine health check, which led to a very worrying and stressful time. However, from my very first consultation with Dr Syed Ahsan, those concerns were quickly eased. His calm, reassuring manner, clear explanations, and expert guidance gave me confidence and clarity at a difficult moment. The wider team, at the clinic have also been exceptional — from the front desk to those carrying out diagnostic tests, every member of staff has been professional, kind, and supportive. I am extremely grateful for the care I have received. Thank you.

If I could give more than 5 stars to Dr. Ashan, I would ***** I started experiencing SVT in 2022. I was a 32 year old, fit female. Naturally, this was overwhelming and unknown as I didn't understand what was happening to my body. After seeing countless cardiologists, I finally found Dr. Ashan and I have never looked back since. He immediately diagnosed me correctly and had a plan of action. Not only was it evident from the beginning that he is a highly specialised expert in the field, but his nature is very calming and he gives you time. Never forcing you to make a decision. I finally decided to have the catheter ablation done in March 2025 in the Cromwell Hospital and my life has completely changed. I had a textbook AVNRT type of tachycardia and he and the team managed to successfully ablate the extra electrical pathway. The whole process was like a well oiled machine and as I was only sedated, I managed to be present at times throughout the procedure which turned out extremely interesting. Dr. Ashan kept speaking to me through the whole process and the environment was calming even though there is a large group of people part of the process. I experienced no pain or discomfort throughout the surgery. I couldn't believe when they were done as I felt almost nothing. The Cromwell hospital and the team was exceptional. I am now off my beta blockers and I have experienced no heart discomfort post surgery. The healing of the groin post opp is the most inconvenience you will have post surgery. I wish I had done it sooner and I am grateful to Dr. Ashan and his team. Special mention to Lucy, his receptionist, which is highly organised and will make your life a breeze. Thank you Dr. Ashan - I have my life back.

Dr. Ahsan is the most compassionate healthcare professional I have had the pleasure of engaging with. He takes his time to convey complex medical information in a simple way, and takes care in setting expectations around potential diagnoses and treatment options. I can't thank him enough for his care.

I contacted Dr Ahsan to secure proper advice regarding treatment for atrial fibrillation and avoid treatment delays. A range of treatment options were considered. The advice received was excellent and the planned cardiac ablation procedure was very clearly explained. There were no post - procedure problems. Everything proceeded very smoothly which only reflects the skills of Dr Ahsan and his team. Furthermore, I very much appreciated the management and organisational skills of Lucy Nash, his Practice Manager. I now feel fully recovered and have none of the former symptoms.
