Web14 Dec 2024 · T waves. Inverted T waves in a predominantly positive lead suggest ischaemia or old myocardial infarction. T waves should be upright in V3 to V6. Tall T waves occur in the acute phase of myocardial infarction and in hyperkalaemia. Misplaced leads.

In most leads, the T wave may be positive, negative or biphasic. The height of the T wave should not exceed one-fourth the height of the R wave, one-fourth the height of the Q wave (if Q wave is greater than R wave), or 0.5 mV to 1.0 mV in any lead. •
