  • Other hospitals for patients living in the Croydon area from e.g. Royal Marsden
  • Community based practitioners e.g. Palliative care, CAMHS

Referral criteria


There are no formal criteria for Direct Access ECG.

The GP needs to give an indication for the ECG on the request form and if it is not appropriate someone from the Cardiology Department will contact the surgery to discuss.

A list of current medications, BP, diabetes status and any other relevant information is also required.


Ambulatory ECG monitoring (24hr)

Referral criteria are as follows:

  1. Palpitations
  2. Paroxysmal Tachycardia
  3. Dizzy spells (near Syncope)
  4. Loss of consciousness

Note: The duration and frequency of the symptoms must be stated on the form. This data is essential in order to decide which type of recorder is given to the patient.

Please also state whether the patient is on any cardioactive medication which could affect the cardiac rhythm, conduction or the ECG complex itself e.g. cold/flu remedies, bronchodilator, bête blocker, calcium channel blockers or digoxin.


Ambulatory Blood Pressure Monitoring (24hr)

Referral criteria are as follows:

Sustained Hypertension – To confirm or exclude the need for anti-hypertensive treatment in patients with possible white coat or borderline hypertension is present.

NotePatients must be off ALL antihypertensive medication for at least four weeks prior to the test.

To assess treatment – To assess response to anti-hypertensive therapy when clinic pressures suggest inadequate blood pressure control.


a) It is essential to state the medication and dosages the patient is taking at the time of the recording 

b) If the patient takes no medication please state this on the request form 

c) It is important that we know if the patient is diabetic

 The request form also asks for a BP recorded at the surgery.



The following indications may be considered for Direct Access:

  1. Asymptomatic murmurs.
  2. Follow up of known mild valve abnormalities.
  3. Atrial fibrillation to evaluate thrombo-embolic risk and evaluate left ventricular function.
  4. Hypertension to evaluate possible hypertrophy.
  5. To exclude Cardiomyopathy

Patients in the following situations are unlikely to be suitable for DA echo referral:

  1. Clinical suspicion of heart failure (see Heart Failure Pathway)
  2. Clinical suspicion of endocarditis (Outpatient Cardiology Referral).
  3. Signs or symptoms of significant valve disease (Outpatient Cardiology Referral).

Patients with suspected heart failure should be investigated with BNP using the existing Heart Failure Pathway and One Stop Heart Failure Clinic at CUH.

Patients with severe abnormalities on echo will be booked directly into a cardiology clinic or be seen by the appropriate acute cardiology service at CUH.

NOTE: This is an adult only service and no referrals on patients under 16 will be accepted.
