ECG-Derived Respiration

by RB | May 16, 2020 | Heart Rate Variability

Several techniques can be used to obtain a respiration signal from an ECG. A popular technique used in bedside patient monitors involves measuring transthoracic impedance using the ECG electrodes. Unlike those described below, this method obtains the respiration signal from the ECG electrodes rather than from the ECG signal. It requires special-purpose hardware and is not suited to recovering respiration from a recorded ECG, but it has the significant advantage (relative to the other methods mentioned here) that a continuous respiration-related waveform can be obtained.
