ECG ANALYSIS

The ECG analysis is the result of electro cardio-graphic signal assessment collected from a patient during the procedural test.

The ECG ANALYSIS can give signals of arrhythmic cardiac events, which can be EXTRASYSTOLES (cardiac premature heart beats). They are an early warning signal for possible cardiac problems as myocardial ischaemia - decreased oxygen supply to cardiac myofibers or different kinds of cardiomyopathy (Is a disease or disorder of the heart muscle; Cardiomyopathy can result from numerous causes, including congenital defects, acute or chronic infections, coronary artery disease, drugs and toxins, metabolic disorders, connective tissue disorders, or nutritional deficiencies. In some patients, the cause is unknown).

The relation between supraventricular or ventricular extrasystoles and health risk is obvious because they can precede myocardial infarction. The visual and the automatic detection of camera extrasystoles can be done separately to supplement the indications.

Supraventricular extrasystoles are colored in green-blue. Ventricular extrasystoles are colored in dark- green. Artifacts are colored in black.

The ECG ANALYSIS covers the following functionalities:

*   Mean Results

*   ECG

*   Advance

*   Summary

*   QRS analysis

RESULTS

This page presents the numerical values of the basic data inferred from the ECG signal recorded from the examined patient. The summary includes the number of cardiointervals recorded during the test, the registered artifacts (if any), the QRS complexes, the registered vascular extrasystoles (if any) and the registered supraventricular extrasystoles (if any).

The summarized data can be printed.

ECG

Two graphs are displayed – one is the whole extract of the recorded ECG signal and the other is a zoomed version of an ECG signal extract that was selected and marked on the top upper graph.

At the bottom of the screen on the left side the numerical values of P, Q, R, S, T, R-R values are presented together with their corresponding wave amplitude values and the wave distances.

The analog analysis option gives the mean distance: between: “P” and “Q”; “Q” and “R”; “R” and “S”; “S” and “T” and the mean amplitude of “P”, “Q”, “R”, “S” and “T”.

The mean ECG is presented. It is possible to obtain the same information for every single cardiac beat.

ADVANCE

The ADVANCE screen presents extracts of the most important graphs and the results calculated by Dantest. The presented graphs include:

-  QRS analysis

-  Scatterogram

-  Spectrum

-  Spectrogram

All the four graphs can provide detailed information.

SUMMARY

The SUMMARY page presents a quantitative format of the patient results.

QRS ANALYSIS

This page provides details on a separate QRS curve. Review of each recorded cardio signal is possible and its numerical values can be recorded.

ALL CHANNELS

This functionality allows simultaneous review, comparison and analysis of the several channels of the ECG curve.
