An Electrocardiogram (EKG or ECG) is a non-invasive cardiac test that checks for problems with the electrical activity of your heart. An ECG is used to measure the heart’s electrical conduction system. It picks up electrical impulses generated by the depolarization and repolarization of cardiac tissue and translates into a waveform. Moreover, it helps detect abnormal blood supply (Ischaemia), abnormal impulse generation and propagation.

An Echocardiogram is an ultrasound scan of the heart. It is sometimes just called an ‘ECHO‘. Ultrasound is a very high-frequency sound that you cannot hear, but it can be emitted and detected by special machines. The scan can give accurate pictures of the heart muscle, the heart chambers, and structures within the heart such as the valves. It helps to access the contraction and relaxation pattern of the heart and gives information on causes of heart diseases.

Spirometry is a test that helps to measure lung volumes and airway flow pattern. It can help diagnose various lung conditions, most commonly Chronic Obstructive Pulmonary Disease (COPD). Spirometry is also used to monitor the severity of some other lung conditions, and their response to treatment.
