Noninvasive Imaging of Cardiac Electrophysiology
Noninvasive imaging of cardiac electrophysiology is still a major goal despite all recent technical innovations. This review gives an overview about the historical background, recent developments and possible future applications of noninvasive imaging of cardiac electrophysiology.
متن کاملNoninvasive Imaging of Cardiac Electrophysiology (NICE)
Computer modeling of bioelectric activity has been of interest in cardiac electrophysiology for several decades (Gulrajani R. M., 1988; Johnson J. R., 1997; Modre R. et al., 2001). Additionally, noninvasive imaging of the electrical excitation from recorded electrocardiograms (ECGs) has become a diagnosis tool in clinical electrophysiology (Modre R. et al., 2003; Ramanathan C. et al., 2004). No...
متن کاملCardiac arrhythmia visualization in a virtual heart for electrophysiology education
The 3D cardiac arrhythmia visualization model in this paper was developed to assist medical students and fellows in understanding the underlying electrophysiology of cardiac arrhythmias and their treatments. In this detailed cardiac model, the user can freely move to any position of the heart and observe it from any point of view. A transparent mode is applied to facilitate a more detailed expl...
متن کاملInvestigating Electrocardiographic Features in Fuzzy Models for Cardiac Arrhythmia Classiication
Simple and composed measures of the electrocardiographic (ECG) waveshape are generally used to detect and classify diierent kinds of cardiac arrhythmic beats. In the last years, the development of computer technique allowed an increasing number of electrocardiographic measurements to be extracted and stored for each cardiac beat. As a consequence, analysis systems of any kind result to be more ...

Saturation Artifact If a 3-mV peak signal is being amplified at a gain of 5000, the final output will be 15 000 mV or 15 V; however, if the system supply voltage is limited to 10 V, the overall signal amplitude would be limited to about 9.5 V (slightly below the supply voltage). The signal would simply be cut off above 9.5 V, although the amplifiers would attempt to drive themselves up to the r...
