The Hazards of Frequently Undergoing Electrocardiograms (ECGs)

Under normal circumstances, undergoing frequent electrocardiograms (ECGs) poses no harm to the human body.

An ECG is a non-invasive, radiation-free, and painless diagnostic method that assesses cardiac health by recording the heart's electrical activity. Electrodes are placed on specific locations on the body surface to record the heart's electrical signals. This process is safe and harmless. From a physiological perspective, the ECG procedure itself does not cause any damage to the body. It does not involve radiation or other harmful substances; it simply records the heart's electrical signals through electrodes attached to the skin, thus carrying no risk of radiation exposure or physical injury. Furthermore, ECG equipment meets high safety standards, with leakage current less than 0.01mA, allowing direct cardiac examination with a high level of safety.

However, in situations where medical resources are limited, excessive unnecessary testing can consume resources that could otherwise be used for patients in genuine need, thereby affecting medical efficiency and fairness. Therefore, while ECG is a safe diagnostic tool, its use should be based on clinical necessity, avoiding unwarranted repeat examinations to ensure timely detection of diseases while minimizing unnecessary physical and psychological burdens and resource waste.
