Advanced features of ECG mapping

Abstract

Cardiovascular diseases are the leading cause of death worldwide. A great number of methods have been developed to monitor the state of the heart, each of which has its own advantages and limitations. One of the most promising method is surface mapping. To improve reliability and informativity of this method, researchers of Medical Engineering Laboratory of TPU developed nanosensors with unique metrological characteristics for non-invasive measurement of ECG signals of microvolt and nanovolt levels. The results of previous studies showed that metrological characteristics of the developed nanosensors significantly exceed those of conventional electrodes. Based on this, nanosensors used for surface ECG mapping will enable qualitative improvement of data obtained and diagnostic capabilities of this method.
