An ECG machine, also known as an electrocardiograph, is an important diagnostic device used in hospitals, clinics, and diagnostic centers to measure and record the electrical activity of the heart. It provides a graphical representation of heart rhythms, allowing healthcare professionals to identify abnormalities such as irregular heartbeats, heart attacks, and other cardiac conditions.

ECG machines are widely used for routine heart checkups, emergency diagnosis, and continuous cardiac monitoring. Modern ECG systems are designed with digital displays, easy operation, and accurate recording capabilities, making them an essential tool for cardiology departments and medical facilities that require reliable heart monitoring and diagnostic support.
