ECG changes in hypertrophic cardiomyopathy

Last reviewed 01/2018

  • evidence of left ventricular hypertrophy - however the pattern is very variable so there is not a typical ECG pattern

  • other possible features include:
    • often an odd axis, abnormal Q waves, deep S-waves and poor R-wave progression
    • changes suggestive of pre-excitation e.g. short PR interval, delta-waves
