Dr. Karthik Sabapathy is always professional and compassionate. He relates well to people and takes time to listen and takes appropriate action on the symptoms. He is good at building trust with his patients. Im so glad I choose KSM clinic and could highly recommend to anyone.
Had chest pain and visited Dr karthik, ECG and echo was done by a good female technician ,sir can explain about our condition very clearly he told it is heart burn due to gastritis. He advised some medication for gastritis. My chest pain cured within 2 days. Very happy.
A patient person who takes time to listen,understand and explain things to patient. Goes beyond his call of duty in assuring the patient of their condition and what would be the course of treatment.
Wishing the doctor all the best for his future
I consulted Dr.Karthik Sabapthy to get a cardiology opinion. He listen to all our concern and answered all our questions patiently. He was so friendly and simple by nature. He gave me so much of mental support which is the best medicine I need. I truly recommend this doctor.

As per his advice we did treadmill echo and it showed some block which sir explained to us . He himself did angio stenting for the block .thanks sir your prompt treatment. Our family is always indebted to you 🙏🙏
Very friendly receptionist. Hospital is very neat and clean. Doctor is very friendly, listened politely to all our issues. Did not complicate, he said everything is normal after seeing all the reports and suggested gastic tablets. (He did not panic me with complicated terms)… Much much satisfied.
