ECG is a process of recording the electrical signals associated with cardiac activity over a period of time. It has become a routine part of any medical evaluation and has been used as a diagnostic test in the past seven decades. ECG is used for the diagnosis and treatment of various types of heart conditions such as myocardial infarctions (heart attacks) and arrhythmias (abnormal heart rhythms). ECG is a non-invasive procedure used for the diagnosis of heart conditions. The rising incidences of CVDs have led to the rise in the use of ECG devices. The ECG devices market is further segmented into resting ECGs, stress testing, cardiopulmonary stress testing, and Holter monitoring systems.
