WebT waves represent repolarisation of the heart, and undergo temporary or permanent change. Normal: T waves down in V1, V2, never V3, sometimes in III and aVF (1). The T wave may be normally inverted or upright in III and in V1 (and in V2 in young people, and also in V3 in some Afro-Caribbeans). WebTo illustrate the point, 50% of normal 3–5 year old children will have inverted T waves in V2 but in the 8–12 year age group inverted T waves in V2 will be present in only 5–10% of individuals. The T wave in V5 and V6 should be upright at all ages, but in a very small number of newborn babies the T wave in these leads may be flat or inverted for 1–3 days.

Web11. Are the T Waves Normal? T waves can be positive, negative or biphasic in dogs and cats. Tall spiked T waves are seen with hyperkalemia. Tall T waves may be seen with ventricular enlargement, conduction disturbances. Small T waves are seen with hypokalemia. T wave abnormalities may also result from myocardial hypoxia, myocardial infarction ... The refractory period of cardiac muscle is distinct from that of skeletal muscle. Nerves that innervate skeletal muscle have an extremely short refractory period after being subjected to an action potential (of the order of 1 ms). This can lead to sustained or tetanic contraction. In the heart, contractions must be spaced to maintain a rhythm. Unlike in muscle, repolarization occurs at a slow rate (100 ms). This prevents the heart from undergoing sustained contractions becaus…
