Our ECG machines were especially designed for fast and simple operation. They are suitable for detection and diagnosis of heart abnormalities, but with the many possible upgrades that can be added, they can do even more. The diagnostics upgrade generates ECG measurements, averaged ECG, QRS axis and mainly the automatic ECG interpretation. External USB printer allows printing on A4 office papers. Spirometry upgrade turns the ECG into combined cardio-pulmonary device. Finally LAN & WiFi helps to make the clinical ECG workflow more effective.
