EKG (Electrocardiogram, ECG)
How the Test is Performed
An ECG is a relatively simple test which involves sticking about ten small electrodes on the chest and attaching them to a machine at the bedside. The machine analyses the heart’s electrical signals, picked up through the electrodes on the skin surface. It is a completely painless test but obviously requires temporary exposure of the chest, to allow placement of the leads. The actual reading takes about one minute and a printout with 12 waveforms is produced either at the machine itself, or at a nearby printer. A doctor or experienced and specialised nurse reads and interprets the ECG. Sometimes they will seek additional help from a more senior doctor or a cardiologist – even at a distance via fax. Occasionally the ECG is formally reported by a cardiologist – this is more likely in the routine or non-urgent situation.
