Systems, devices and methods for advanced electrode management in neurological monitoring applications include receiving sockets configured to receive connectors having groups of electrodes. The physician is not required to manually map each electrode with its corresponding input channel. Electrodes are coupled to the corresponding input channels in groups through connectors having a unique identification (ID). The system is configured to read the unique ID of each connector and establish its identity. Based on the ID, the system configures itself to automatically correlate or associate each electrode with its corresponding input channel when the connectors are first inserted into the receiving sockets, and again if the connectors are removed and re-inserted into different positions in the receiving sockets, to insure the electrodes are always mapped to the same input channels.

Disclosed herein are methods, systems, and devices for identifying increased likelihood of non-ST elevation myocardial infarction (NSTEMI) in a patient based on ECG data. The methods can include determining based on the ECG data that the patient lacks ST elevation (STE) and that the patient exhibits a ventricular repolarization dispersion (VRD) score that exceeds a predetermined threshold value. The VRD score can be based in part on a T wave complexity ratio that serves as a temporal marker of VRD for the patient. Other markers of spatial and time qualities of repolarization can also be included in the VRD score. An elevated VRD score in the absence of STE can indicate a likelihood of NSTEMI in the patient and a potential major adverse cardiac event.

A portable medical device having an intravenous line flow sensor integrated into a cable. The portable medical device may be a defibrillator having an ECG or electrode cable couple to ECG or electrode leads. The flow sensor may be integrated into the ECG or electrode cable. The portable medical device uses the flow sensor to capture and store information about fluids delivered to a patient being treated with the portable medical device. The information may include total volume provided, flow rate, and the like. The information may then be used to evaluate the treatment provided to the patient.

The present disclosure is related to methods, systems and apparatus for performing electrophysiological measurements utilizing three or more electrodes attached to a patient.
