Overview

An ECG may be helpful in the diagnosis of altitude sickness. Findings on an ECG suggestive of altitude sickness include shortening of R-R interval, shortening of the lengthening of Q-T and in particular for the ST-T flattening and Increase of P wave.

Electrocardiogram

  • An ECG may be helpful in the diagnosis of altitude sickness. Findings on an ECG suggestive of altitude sickness include:[1][2]
    • Shortening of R-R interval
    • Shortening of the lengthening of Q-T and in particular for the ST-T flattening
    • Increase of P wave
    • Prolongation of P-Q
    • Deviation of the R vector
    • T wave flattening in the left precordial leads
