Abstract
This article proposes new solutions for visualization of biomedical signals in development and operation of cardiodiagnostics telemedicine systems. Visual evaluation of bioparameters is based on multilevel wavelet analysis of recorded patient’s acoustic signals describing current state of the cardiovascular system, respiratory system and speech system. Proposed visualization solutions are implemented in form of ACUSTOCARD and ACUSTOMED telemedicine systems. Developed ACUSTOCARD telemedicine system being a set of software and hardware tools helps to find any cardiovascular diseases at earlier stages. ACUSTOMED is a further step of ACUSTOCARD telemedicine system, which additionally allows receiving acoustic sonograms of breath sounds and wavelet- sonograms of speech signals to evaluate the level of patient’s emotional tension.
Scope of application of ACUSTOMED telemedicine system includes as follows: instant diagnostics of the cardiovascular system; operational monitoring of the heart state for patients after the cardiac surgery; pediatric cardiology; sports medicine; home telemedicine.
Experimental testing of biomedical signal visualization technology in cardiodiagnostics telemedicine systems confirms its high efficiency.
Keywords: acoustic cardiography, biomedical signals, multilevel wavelet analysis, telemedicine system.
