Cardiax PC
Sistem ECG computerizat cu 12 canale
Constructia sistemului
Sistemul poate fi configurat cu orice PC IBM compatibil.
Configuratia minima recomandata: procesor 1000 Mhz, 256 MB RAM, 40 giga HDD, port USB disponibil
Sistemul se compune din:
- modul de achizitie cu cabluri de pacienti si electrozi
- software CARDIAX (Win 98 / 2000 / Milenium / XP) care memoreaza, prelucreaza si interpreteaza semnalele ECG, disponibil si īn limba romāna
Comunicarea cu calculatorul se realizeaza prin port USB.
Functionarea sistemului
Sistemul ECG CARDIAX poate monitoriza simultan timp nelimitat pe 3, 6 sau 12 canale si poate memora la comanda īnregistrari de 8, 16 sau 32 de secunde. Utilizarea modulului Long play permite memorarea unor īnregistrari de lunga durata (pāna la 24 ore).
Fisa individuala a fiecarui pacient contine datele generale ale pacientului, permite memorarea a 100 electrocardiograme si contine un bloc de observatii īn care pot fi īnscrise 10 pagini dactilografiate. Sistemul este capabil sa administreze o baza de date mare (5 milioane īnregistrari) inclusiv īn retea locala, fara arhivare. Electrocardiogramele memorate pot fi revazute oricānd static sau īn miscare īn timp real.
Pentru analiza īnregistrarilor se pot folosi riglele electronice sau interpretarea automata (codul Minnesota) ce consta īn:
- calcularea medianelor
- calcularea parametrilor specifici celor 12 derivatii
- propunerea de diagnostic diferentiat: pediatric si adult
Complexele QRS pot fi marite.
Vizualizarea simultana a īnregistrarilor facute la date diferite ofera posibilitatea compararii lor. Cu medianele selectate se genereaza o figura tridimensionala care se poate roti īn toate directiile. Din īnregistrarile de tip Frank se pot obtine vectorcardiograme, bi si tridimensionale.
Electrocardiogramele memorate se pot tipari cu orice tip de imprimanta pe hīrtie obisnuita format A4.
Optional se pot atasa urmatoarele module:
- Ergometrie. Acest modul este capabil sa comande automat un ergometru, sa memoreze complet pe 12 canale traseele din timpul testului si sa analizeze rezultatele obtinute
- Modul de lucru īn retea
- Spirometrie
- Monitorizarea saturatiei de oxigen (SPO2)
EC-12S
Stress Test System for bicycle or treadmill
The PC based 12 channel ECG and blood pressure monitor in the EC-12S device was constructed for the execution of diagnostic exercise testing. With the help of the exercise evaluating program the load can be continuously set to the desired level. The whole examination is conducted with continuous monitoring, underlain by multi level event monitoring and alarming. The analyzing program performs continuous ST and rhythm analysis during the testing and the deviations within and outside the professionally accepted intervals are visually presented. During the exercise testing the change of heart rate, blood pressure and MET as a function of time and further parameters can be continuously evaluated. The whole examination is saved, so the events may be evaluated retrospectively.
