However, a negative T wave is normal in lead aVR. Lead V1 may have a T wave with positive, negative, or biphasic where positive is followed by negative, or vice versa. In addition, it is not uncommon to have an isolated negative T wave in lead III, aVL, or aVF.

Tre extremitetavledningar (I, II och III) »skapas« från elektroder placerade på vänster arm, höger arm och vänster ben. Dessa tre elektroder skapar även de tre s k unipolära extremitetsavledningarna aVL, –aVR och aVF. The electrocardiograph defines one electrode as exploring (positive) and the other as reference (negative) electrode. In most leads, however, the reference is actually composed of a combination of two or three electrodes. Understanding 12-Lead EKG’s Basic 12-Lead interpretation . Jeffrey J Dunn, DNP, ACNP-BC, CCRN .

The T wave is normally upright in leads I, II, and V2 to V6; inverted in lead aVR; and variable in leads III, aVL, aVF, and V1. In general, an inverted T wave in a single lead in one anatomic segment ( i.e., inferior, lateral, or anterior) is unlikely to represent acute pathology; for instance, a single inverted T wave in either lead III or aVF

T wave inversion in leads iii and avf can represent normal findings, but in the appropriate clinical setting, can indicate that further evaluation of the heart is needed. Här behöver man bara veta åt vilka håll alla extremitetsavledningarna pekar. De som pekar mer än 90 grader ifrån hjärtvektorn får ett negativt utslag. Hjärtvektorn pekar rakt nedåt vilket gör att avledning I får ett blankt utslag. II och III pekar snett nedåt och är därför positiva. aVF och -aVR likaså.

However, Left axis deviation is defined as between -30 and -90, so in this scenario, the QRS axis could fall between 0 and -30, which is within normal limits. normal variant, advanced pregnancy or obesity, myocardial infarction, hypertrophy, arrhythmias, chronic lung disease, and pulmonary embolism.
