ECG machines are an important part of medical equipment that can be used to record the electrical signals of the human heart activity. The use of displays in ECG machines can help doctors and nurses better understand and analyze data from the heart's electrical signals in order to more effectively differentiate various cardiac conditions and provide a better basis for patient treatment.

First, the display on an ECG machine is usually used to show the patient's ECG waveform. Often ECG waveforms are irregular and complex, and drawing them on traditional drawings can be difficult to identify, but using a high-quality monitor can make the waveforms clearer, more visible, and easier to read, compare, and diagnose. This display can be geared toward physicians and nurses to better understand and analyze ECG waveforms, providing them with a faster and more accurate diagnosis of cardiac conditions.

Second, the display of modern ECG machines is no longer limited to conveying ECG waveform data. Many of today's advanced devices are equipped with high-resolution displays and reporting capabilities that can be used to display a wide variety of data information such as patient information, audio recordings, ECG lead methods, and more. This data is managed and stored through modern processing systems that allow administrators to view, edit and transfer data for transfer and discussion between physicians, patients and hospitals.

Finally, the high quality display on the ECG machine allows results to be obtained through a wireless interface. Conventional ECG machines are usually connected by cables that require moving leads to the right location, which is often time consuming, laborious, inconvenient and difficult. To be precise, some difficult patients have multiple shots in some areas, and the use of wireless displays can effectively improve the monitoring range, and in this case the communication between therapist and patient is also easier and more efficient.

In conclusion, modern display technology is a clear improvement to ECG machines, they can assist doctors and nurses in the rapid, accurate and more comprehensive analysis of the patient's ECG signal, providing a strong guarantee of improved diagnostic accuracy and relevance.
