q2 · i? · review · r3

Review synthesis of studies using HRV time-domain metrics (SDNN n = 9, RMSSD n = 5, AVNN n = 4). The review reports "these three metrics decreased significantly during surgical procedures", in line with previous research describing decreases when stressors are present.

"In all applicable studies, the authors concluded that these three metrics decreased significantly during surgical procedures [20, 58, 60, 76, 86]."
