Visited this clinic today with my wife for a cardiology consultation and had a great experience! The doctor took the time to clearly explain the symptoms and thoroughly reviewed the ECG report. Thankfully, everything looked normal and we were reassured. I’d definitely recommend this clinic for any cardio-related issues. Professional, knowledgeable, and caring staff. Thank you Doctor.

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
