Electrocardiogram (ECG)


Our clinic nurses are trained in performing a 12-lead ECG (electrocardiogram) to assist in diagnosis of cardiac arrhythmias and other heart conditions.  The ECG is interpreted by your doctor.

An electrocardiogram (ECG) is a medical test that detects cardiac (heart) abnormalities.  This is done by measuring the electrical activity generated by the heart as it contracts.   The machine that records the patient’s ECG is called an electrocardiograph.   An electrocardiograph records the electrical activity of the heart muscle and displays this data as a trace on a screen or on paper.   This data is then interpreted by a medical practitioner.   ECGs from normal, healthy hearts have a characteristic shape.   Any irregularity in the heart rhythm or damage to the heart muscle can change the electrical activity of the heart so that the shape of the ECG is changed.

A doctor may recommend an ECG for patients for the following reasons

  • Assessment of any heart rhythm problems
  • Evaluate any enlargement of the heart as a result of elevated blood pressure
  • Assessment and management of any characteristic heart symptoms
