Patient monitoring systems and methods that detect interference with pacemaker

Abstract:

A patient monitoring system includes a heart rate monitor that monitors the physiological parameter from a patient and provides a heart rate indicator based on the physiological parameter, an impedance respiration monitor that measures impedance of the patient's chest and provides a respiration rate, a processor, and an interference detection module. The interference detection module is executable to determine a baseline heart rate while the impedance respiration monitor is not active. The impedance respiration monitor is then activated to measure impedance of the patient's chest to provide the respiration rate. Upon activating the impedance respiration monitor, the interference detection module is executable to assess the heart rate indicator for an interference check period and detect a threshold change in the heart indicator compared to the baseline heart rate during the interference check period. Upon detecting the threshold change, an interference alert is generated to notify a clinician regarding interference with a pacemaker on the patient.
