One Heart Clinic is a private cardiology and diagnostic centre at 68 Harley Street in Marylebone, London. It was founded by consultant cardiologists Dr Ravi Assomull, Dr Fakhar Khan and Dr Sayan Sen, and is registered with the Care Quality Commission. The clinic operates across nine UK sites and works with a panel of more than 20 consultant cardiologists, several of whom hold FRCP and FESC credentials and academic professorships.

Its cardiopulmonary exercise test (CPET) is described as a non-invasive assessment performed on a treadmill or stationary bike that measures VO2 (oxygen consumption), VCO2 (carbon dioxide production), heart rate and blood pressure. The clinic frames CPET both for clinical cardiovascular and respiratory assessment and for performance and longevity. The Harley Street site also provides resting and ambulatory ECG, echocardiography, 24-hour blood pressure monitoring and on-site cardiac CT, with cardiac MRI available at the nearby Marylebone centre.

CPET is delivered through consultant-led referral rather than as a standalone published-price test, and the clinic states its admin team confirms consultation and test costs before booking. Published pricing is available for its condition-specific memberships, which start at GBP 103 per month for the Pacing membership and include an annual consultation, echocardiogram and blood tests. London clinics open 9am to 7pm Monday to Friday, and most major UK and various international insurers are accepted.
