Each member of our frontline clinical team is a UK-qualified cardiac physiologist with experience working in NHS cardiology departments. Every ECG report is produced and signed by one of our clinicians, who are accountable for the report’s accuracy and available to discuss the report if needed. All our work undergoes a continuous rolling audit by our board of consultant cardiologists, which includes both adult and paediatric specialties. Our technical staff and software development team are all in-house to ensure all our systems stay robust and work for you.
