ECG (Electrocardiogram)

ECG is a recording of the electrical activity of the heart. Six electrodes are placed on the chest and one electrode on each arm and leg. The electrical activity produced by the heart is received and recorded onto a chart. A trained cardiographer performs the procedure, which takes about ten minutes. The results help the patient’s doctor to determine the rate and rhythm of the heart and also to diagnose other conditions.

Ambulatory ECG monitoring

Ambulatory monitoring manually records the electrical activity of the heart over a period of about 20 minutes.

A number of electrodes (depending on the device used) are placed on the chest and connected to a recording device. The patient can carry on as normal.

The patient’s doctor can determine the rate and rhythm of the heart over the period of the recording. It can help with the diagnosis of various medical conditions and show how effective a treatment is.
