Cardiosoft Software software#

Among the different cardiovascular diseases, the arterial hypertension (HTA), the coronary artery disease (CAD), and the ischemic cardiomyopathy are the most common. This health problem increases the need for medical service and has an important impact on health costs. IntroductionД¬ardiovascular diseases are the leading cause of death globally, and they are also the first motivation for medical consultation.

In this case, the validation is performed by comparing the estimated QT interval with respect to the estimation obtained using the Cardiosoft software providing a percent error of. The usefulness of this software tool is also tested by considering the analysis of the ECG signals for a group of 60 patients acquired using our digital electrocardiograph. The validation of the QT interval measurement algorithm is attained using the Physionet PTB diagnostic ECG database showing a percent error of with respect to the database annotations.

The QT interval is estimated by updating the QT interval on each lead, considering shifting techniques with respect to a valid beat template. This enables segmentation of the current beat for obtaining the P, QRS, and T waves. Two fiducial points ( and ) are estimated using the SVM algorithm on each incoming beat. The software enables off-line ECG processing including QRS detection as well as an accurate multilead QT interval detection algorithm using support vector machines (SVMs).

This work reports a multilead QT interval measurement algorithm for a high-resolution digital electrocardiograph.
