What Does a Cardiac Physiologist Do?
Cardiac physiologists are healthcare professionals who specialise in helping diagnose and treat conditions affecting the heart and blood vessels. They work alongside doctors, nurses and other clinical staff to provide care for patients with cardiac problems.
The role involves operating specialist equipment, carrying out diagnostic tests and monitoring patients during procedures. You might record electrocardiograms (ECGs), assist during catheter procedures or help prepare patients for treatment. Administrative tasks also form part of the job, including scheduling appointments, maintaining patient records and reviewing test results under a physician's guidance.
Day to day, you could find yourself monitoring changes in a patient's heart rhythm, explaining procedures to patients and their families, or ensuring equipment is properly maintained and calibrated. The work requires attention to detail, strong communication skills and the ability to remain calm under pressure. Empathy and teamwork are equally important, given the close contact with patients who may be anxious about their cardiac health.

The chance to work directly with specialist technology and play a meaningful role in patient diagnosis draws many people to this career. The main distinction is between invasive and non-invasive work.
Non-invasive cardiology involves diagnostic tests that do not require entering the body. This includes performing ECGs, fitting ambulatory monitors that patients wear at home, and carrying out echocardiograms. Echocardiography uses ultrasound technology to create images of the heart, allowing doctors to assess how well it is functioning.
Invasive cardiology involves assisting with procedures such as cardiac catheterisation, where a thin tube is guided through blood vessels to the heart. Physiologists in this area may work in catheter laboratories, supporting the clinical team during angioplasty procedures or the fitting of pacemakers.
Some physiologists also specialise in vascular technology, focusing on conditions affecting blood vessels elsewhere in the body. Others may work specifically with exercise testing, monitoring patients as they use treadmills or exercise bikes to assess cardiac function under physical stress.

Training and Entry Requirements
The standard entry route in the UK is the Practitioner Training Programme (PTP), a BSc (Hons) in Healthcare Science with a specialism in Cardiac Physiology. This is run through the NHS and accredited by the National School of Healthcare Science, typically taking three years to complete.
Some people enter through a relevant foundation degree or higher national diploma in cardiac physiology, clinical physiology or a related healthcare science subject. Certain NHS trusts offer apprenticeship programmes that combine work with study.
Voluntary registration with the Registration Council for Clinical Physiologists (RCCP) demonstrates professional competence and is valued by employers. Registration with the Health and Care Professions Council (HCPC) is not currently required for cardiac physiologists, though this may change in the future.
Continuing professional development is important for keeping pace with advances in cardiac technology and maintaining clinical competence. For current information on qualifications and training pathways, the Health Careers website provides detailed guidance, including information on the scientist training programme (STP) for those wishing to progress further.
Where You Might Work
Most cardiac physiologists work within the NHS, in settings such as:
- Hospital cardiology departments
- Cardiac catheter laboratories
- Outpatient clinics
- Community diagnostic centres
Private hospitals and specialist cardiac centres also employ physiologists. Some roles involve travelling between sites or working in mobile screening units.
Working hours will depend on your employer and specialism. Many positions follow standard weekday hours, though hospital roles may include shift work, weekends or on-call duties to cover emergencies.
Salaries in the NHS are set according to the Agenda for Change pay bands. Most cardiac physiologist roles fall within bands 4 to 6, depending on experience and responsibilities. Pay scales are updated regularly, so check the NHS Employers website or GOV.UK for current figures.
Career progression can lead to senior positions, team leadership or advanced clinical practice. Some physiologists go on to complete further training through the scientist training programme to take on broader clinical responsibilities.
