Stress Test System Machine ECG Stress with Treadmill
Introduction
The Stress ECG Analysis System is consist of sampling hardware device, special software system and exercise equipment. Its functions include 12 leads ECG synchronously sampling, and data storage, ST segment analysis, ECG review in dynamic/static/superimposed during the whole exercise process, and trend chart analysis of multiple parameters, multiple printable report, etc. The patient's exercise state can be recorded timely and accurately, which reflects patient's heart function, providing reliable data for doctors in diagnoses.
Features
1. Print ECG waveform in real-time during sampling process, record and save ECG data of whole process.
2. Observation of the changes of ST segment in real-time, enlargement display of user selected lead, automatic calculation of ST related data.
3. Stress ECG Adopt anti-interference technology to ensure the stabilization of baseline, reduce the effect on ECG waveform from EMG interference, baseline drift and AC interference.
4. Available for both standard and user-defined exercise scheme, automatic instantaneous notice of print and BP measure can be set according to exercise phrase.
5. Operator can mark events during exercise, the ECG waveform of marked event can be compared with current waveform. The event can be observed, edited and printed after excise.
6. Display and print of all kinds of trend chart. Mainly including: HR, BP, METS, HR*BP, exercise trend, ST segment level/influence/slope/3D/J level and ST/HR, etc.
7. Dynamic/static review function after exercise, representation of the whole exercise testing process.
8. Case Import/Export function. Compress the case for storage, which takes up less disk space. The compressed case shall be associated with the file type in operation system. This will make the import operation much more simple and quick.
9. System setting function includes multiple setting items. For example, switching Chinese/English language, format and mode of displaying waveform (12 leads * 1column / 6leads * 1column / 6leads * 2columns / 3leads * 2columns / 3 leads * 1column, etc), color of background, print related setting, filter setting and displaying of optional parameters, etc.
10. Provide multiple functional tools, which are used for device management, cases statistics and other operations.
11. mode of ECG data sampling, improves the anti-interference capability.
12. Supportive for variety types of exercise equipment
