Resting electrocardiocram (ECG) – a test used to check heart rhythm and electrical activity. This simple investigation helps to diagnose cardiovascular system diseases. The electrocardiocram shows various cardiac arrhythmias, cardiac conduction system injury, ischemic heart muscle changes (previous myocardial infarction).
Exercise stress test – an electrocardiocram is recorded during exercise which allows the specialist to compare heart circulation at rest and during maximum physical exertion. An increase in heart muscle work and oxygen demand may reveal heart problems that may not be seen otherwise.
