This publication summarises and critically appraises the current published literature on heart rate variability (HRV) monitoring as applied in tactical organisations. Military, fire and rescue, and law enforcement roles were considered independently, and a systematic review was conducted. Relevant gaps in the literature were identified as they arose. The review was inclusive of methodological considerations, population-specific considerations, and occupationally relevant needs.
