Embodiment Construction

[0027] Reference will now be made in detail to embodiments of the present disclosure, examples of which are illustrated in the accompanying drawings.

[0028] image 3 A data acquisition system 10 for obtaining electrocardiogram (ECG) signals from a patient 12 is shown. The data acquisition system 10 includes a 5-lead ECG main measurement unit 14 that measures ECG signals from electrodes RA, LA, LL and RL. It is known to calculate the pressurized leads aVR, aVL and aVF by comparing the measured voltage from each limb electrode with a reference voltage. Such as image 3 As shown, amplifiers 16 , 18 , 20 and 22 are used to compare the signals from the respective electrodes with a reference signal from the right arm electrode RA, and the output signal from each amplifier is fed to an analog / digital converter 24 . Amplifier 22 is a Right Leg Drive (RLD) amplifier that utilizes the RL electrodes to equalize the body and measure the potential of the electronics. An A / D converter...

Abstract

A data acquisition system for use with expandable ECG electrode systems. The data acquisition system includes a main unit and one or more expansion units for increasing the number of ECG leads appliedto a patient for enhanced monitoring capabilities. Multiple embodiments are illustrated for providing a common mode signal between the main electrode unit and expansion units without requiring the physical transmission of voltage potential between the main unit and the expansion unit. In one embodiment, the main unit and the expansion unit share a common ground reference potential. In a second embodiment, an optical signal is transmitted between the main unit and the extension unit to relay the common mode information while in a third embodiment, common electrode potentials are provided to both the main unit and the extension unit for constructing their own common reference signals.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Patent Application Serial No. 15 / 059,922, filed March 3, 2016, which is hereby incorporated by reference in its entirety. Background technique [0003] The present disclosure generally relates to wireless ECG devices. More specifically, the present disclosure relates to technical solutions for modularly extending wireless ECG devices. [0004] An electrocardiogram (ECG) measures the electrical activity of the heart. It depicts the rate and regularity of the heartbeat, and the presence of heart disease or injury, arrhythmia, etc. The ECG is one of the most important non-invasive diagnostic tools available to cardiologists. ECG is measured by placing electrodes on the patient's chest and limbs and measuring the bioelectric potential generated by the heart. The electrodes attached to the patient are connected by leads to or communicate wirelessly with the ECG monitor for further si...
