Flow diagram of HRV acquisition during ambulance transportation.
HRV was registered in 50 controls. Three registrations were excluded from analysis: one because of technical reasons and 2 because of non-sinus rhythm. HRV parameters were analyzed in 47 controls, matched to the patient population for age and gender (S2 Table).
