What we do

We diagnose and manage both acute (severe and sudden) and chronic (worsens over time) health conditions related to the heart. We treat people requiring both inpatient and outpatient care and support. Patients requiring admission are seen in the Acute Assessment Unit (AAU) at Chelsea and Westminster and at the Cardiac Care Unit at West Middlesex.

We run a variety of specialist services and clinics as part of our overall approach to keeping you healthy:

  • General Cardiology Clinic
  • One Stop Clinic
  • Rapid Access Chest Pain Clinic
  • Heart Failure Service and Specialist Arrhythmia Clinic at Chelsea and Westminster
  • Heart Failure Service at West Middlesex

We provide invasive services including:

  • ECGs (echocardiograms) and CT (computerised tomography) scannning
  • Heart and blood pressure monitoring
  • Exercise stress testing
  • Pacemaker insertion
  • Arrythmia clinic
  • Tilt  testing and syncope (loss of consciousness) service

We also have a comprehensive cardiac prevention and rehabilitation service to help people return to health after treatment. In the event that a person requires very specialist cardiac support, we can provide this via The Royal Brompton and Hammersmith hospitals.

Atrial Fibrillation (AF)

Staff at West Middlesex and neighbouring Trusts—alongside GPs, nurses, pharmacists and patients living with AF—have contributed to a series of short, educational ‘No Delays’ AF videos. These were created to help newly diagnosed patients gain a better understanding of their condition—including what happens at the point of diagnosis, as well as treatment.
