I can highly recommend Dr Tallent AME at the Brookdale Medical Centre, Horley
Aviation Medical Services ?. He has a treadmill there and can do the Bruce protocol test, after which he can send the trace with a referal letter to Dr Banerjee, Consultant Cardiologistic at the private Spire Gatwick Park Hospital which is next door
