observation study about the autonomic response after spinal anesthesia
ECG waveforms were continuously recorded using a multichannel polygraphic system (Embla N7000, Natus, Pleasanton, CA). The data were saved at a rate of 1024 Hz directly to a memory card within the device for offline analysis of heart rate variability (HRV) and PPG. All data included in the analysis were obtained from continuous artifact-free ECG recordings for analysis of the immediate effects of spinal anesthesia.
