System and method for superior vena cava areas and detection of vena cava atrial junction

摘要

The reason for described herein, enhance the accuracy of the intravascular catheter placement, and superior vena cava (SVC) electrocardiogram to detect an area (ECG), blood vessels within the electrogram, and a system for improving the processing of an ultrasonic Doppler signal, the device and methods. Embodiments of the present invention, intended to place the intravascular catheter in the lower third of the SVC up to the junction of the SVC and right atrium, called vena cava atrial junction (CAJ) (RA) are doing. In particular, neuro - optimization of the ECG parameters and the ultrasonic Doppler signals using fuzzy logic and / or other processing techniques can be used to provide improved accuracy of detecting the location of the CAJ in vascular catheter placement.BACKGROUND 1
