Heart analysis in 3D visualisation
The CardioDM-06® (Heart Vue™) is significantly different from conventional ECG analysers, as it is based on a new approach to analysing the ECG signals – the ECG Dispersion Mapping (ECG DM) method.
The ECG DM is the analysis of dispersions of the low-amplitude oscillations of the ECG signal in certain intervals of the PQRST complex, which is not available in standard ECG analysis methods.
It therefore facilitates:
- detection and localisation of pathological changes in the heart in early stages
- detection of even small metabolic deviations (shifts of electrolytes, ATP (adenosine triphosphate) concentrations) and other metabolism parameters which precede the ischemic heart damage.
- higher sensitivity and specificity for cardiac diagnoses (at myocardial ischemia the sensitivity is 80% and specificity is 75%). Depending on particular pathology, such sensitivity of the device surpasses standard ECG analysers 7-50 times.
- more efficient distinguishing between arrhythmia and a client’s tension or anxiety
- the use of new information from ECG fluctuations, usually ignored as the “noise”, as compared to conventional ECG devices.
- fast recognition and estimate of cardiac status
- representation of cardiac abnormalities or stress in 3D visualisation instead of demanding measurement and logical analysis, as it is in the standard ECG.
- evaluation of stability of the current heart condition. This is very important, as a heart with large deviations can be stable (these patients often have long survival times), and, by contract, a heart with small deviations can be extremely instable and decrease of dangerously unexpected relapse.
- better monitoring during the therapy thanks to 3D visualisation
- provision of much better diagnostic data, as compared to automatic ECG devices.
The Heart Vue produces not only a conventional ECG record but also a map and analysis of QT dispersions – values of cardiac changes, the so-called heart portrait (3D visualisation). The analysis lasts for 30-60 seconds as the constant monitoring of the ECG signal.
