An electrocardiogram (ECG) is a very useful piece of equipment. As
well as being an important tool in diagnosis and investigation of heart
disease and collapse it is also of great value in monitoring of patients
under general anaesthetic and sedation. An ECG is a measure of the
electrical activity of the heart which allows us to evaluate heart rhythm &
identify any abnormalities/disturbances in this, known as arrhythmias,
which in some cases can be life-threatening. An ECG reading provides
crucial information regarding heart activity & function and can help
identify enlargement of the heart, a common finding in many heart
conditions, which would indicate that further investigation of the heart is
required such as chest x-rays and echocardiograms.
Obtaining an ECG reading is a simple, noninvasive procedure that is
achieved by applying metal clips to the skin over the chest and legs.
