1 Heart rate variability in concussed athletes: A case report using the smartphone electrocardiogram 
Ernest Lai, BS, Kenny Boyd, MS, David Albert, MD, Mario Ciocca, MD, Eugene H. Chung, MD, MSc, FHRS  HeartRhythm Case Reports  Volume 3, Issue 11, Pages (November 2017) DOI: /j.hrcr Copyright © 2017 Heart Rhythm Society Terms and Conditions

2 Figure 1 Time-domain results—RR interval distributions: (A) concussion at rest, (B) concussion postexercise, (C) recovered at rest, and (D) recovered postexercise. HeartRhythm Case Reports 2017 3, DOI: ( /j.hrcr ) Copyright © 2017 Heart Rhythm Society Terms and Conditions

3 Figure 2 Frequency-domain results: (A) concussion at rest, (B) concussion postexercise, (C) recovered at rest, and (D) recovered postexercise. The most noticeable change is in high-frequency power (yellow), which was markedly higher in recovery (both at rest and postexercise). EDR = ECG-derived respiration; PSD = power spectral density.
