12 Lead Resting ECG Valenta™
- Effective algorithms of isoline smoothing and ECG filtration ensure reliable examination results;
- Automatic determination of the ECG parameters with detailed interpretation;
- Automatic pediatric ECG interpretation for patients from one year old;
- 40 sec recording of II lead for rhythm disorder analysis;
- QT dispersion measurement;
- Evaluation of ECG dynamics' by comparing the current curve with any other curve from the archive;
- Upgradeable to the Stress-Test, HRV, Spirometry, etc.;
- Storage of ECG without waste of data in patients electronic case, data exchange within the network.
The program algorithms worked through the ECG database, containing more then 50.000 manually verified curves.
The physicians and programmers have been conducting this program since 1962 for space program. Computer interpretation is based on over 100 elementary statements (Minnesota code).
The program with high accuracy calculates the parameters of all ECG waves. The additional fixed points (e.g. for ST segment 5 additional points!) and other specific features are determined to increase of reliability.
These reasons give us the confidence to state that the our ECG interpretation software is one of the most advanced and reliable.

- Detailed review of the 12 leads and rhythm in various scale;
- Analysis of all ECG parameters, including waveform code tables. It
allows, in particular, determine wandering atrial pacemaker by P wave
amplitude;
- Making your own conclusion to correct the automatic interpretation.
Both variants are saved in computer's memory;
- Comparing of the current ECG with any ECG recorded before by overlaying
the curves on each other;
12 lead resting ECG System including:
- The Recorder Valenta (you need single recorder for all diagnostic methods!);
- Patient cable;
- Software for resting ECG record and processing;
- Automatic interpretation software;
- Database for patients' records;
- Connection kit to PC and user manual.
Recorder Valenta easily hooks up to a serial port of your PC without any plug-in card. Now you can use one ECG recorder on different PC without the need to be a technician.
No IRQ and DMA conflicts inside your PC! - no compatibility problems! - no voiding the computer's warranty!
