Arrythmia Clinic

Arrhythmia Clinic at Alexander House Wimbledon

Palpitations are usually due to a change in the heart rhythm.  They can be short lived and in the majority of cases are usually harmless but they can sometimes signify important underlying heart problems.  A heart rhythm abnormality, or arrhythmia, can also occur without symptoms and may be detected by feeling the pulse at the wrist.

Patient Guide to 24 hour ECG monitoring 
A 24 hour ECG (or Holter monitor) is a continuous tape recording of a patient’s ECG over 24 hours.  It is worn whilst the patient carries out their normal day to day activities, helping the consultant to correlate symptoms such as chest pain, palpitations and feinting.  It will also pick up heart rhythm abnormalities that are asymptomatic but may also reveal signs of ischemia (lack of blood supply to the heart).

Resting ECG

This test provides a recording of the electrical activity in your heart.

The heart has an electrical system that makes sure that the chambers of the heart beat in a regular and synchronised way. The Resting ECG is a recording of this electrical activity, taken whilst you are resting. Self-adhesive pads are attached to the skin of the arms, legs and chest. The test takes approximately 10 minutes and no special clothing is required.

Exercise Stress Test

ETT (exercise tolerence test or exercise stress test).  This measures how the heart responds when you exercise.

Wires are attached and your ECG is recorded whilst you walk on a treadmill. The blood pressure, the rhythm of the heart and your symptoms are also recorded during and after the exercise.  This test will take approximately 30 minutes and you are advised to wear comfortable clothes such as a tracksuit and flat shoes.

Stress and depression can play a significant role in how patients cope with a diagnosis of cardiac disease. Patients who suffer with depression are more likely to develop cardiac problems and this is more significant in women who have depression than men. The private cardiac clinic offers a psychiatric service to diagnose and support patients who are psychologically affected by their cardiac diagnosis. We also offer cardiac screening for patients whose primary problem is stress or depression or whose drugs can cause cardiac side effects.
