Does fasting condition normalize postprandial T-wave inversion on ECG?
Does fasting condition normalize postprandial T-wave inversion on ECG?
Postprandial T-wave inversion can occur without myocardial disease, highlighting the importance of obtaining a fasting ECG in doubtful cases.
Fasting ECG may clarify ambiguous T-wave inversion; case reports leave open whether this avoids unnecessary evaluation pending larger studies.
Three patients are presented with T‐wave inversion after food intake. In all cases the ECG was normal in fasting condition and after exercise. Abnormal T‐waves are found during digitalis treatment, in electrolyte disturbances, and also during anxiety. Postprandial changes in the T‐waves have been described in rather few publications, but a review of the literature seems to indicate that the changes are due to potassium movements over the cellular membrane. It is emphasized that a negative T‐wave in itself is not an indication of myocardial disease. In doubtful cases a fasting ECG should always be taken.
