Abstract
Described herein are systems, devices and methods to increase the accuracy of intravascular catheter placement, and to improve electrocardiogram (ECG), intravascular electrogram, and ultrasound Doppler signal processing to detect the Superior Vena Cava (SVC) area. Embodiments of the invention are intended to place an intravascular catheter within the lower ⅓ of SVC to the junction of the SVC and the right atrium (RA)—called the cavoatrial junction (CAJ). In particular, the improved accuracy of CAJ location detection during an intravascular catheter placement can be provided by optimization of ECG parameters and ultrasound Doppler signal using Neuro-Fuzzy logic and/or other processing techniques.
