WebThe P-wave is virtually always positive in leads aVL, aVF, –aVR, I, V4, V5 and V6. It is negative in lead aVR. The P-wave is frequently biphasic in V1 (occasionally in V2). The negative deflection is normally <1 mm. P-wave duration should be ≤0,12 seconds. P-wave amplitude should be <2,5 mm in the limb leads. WebSep 22, 2024 · The T wave is the ECG manifestation of ventricular repolarization of the cardiac electrical cycle. The T wave is normally upright in leads I, II, and V3 to V6; inverted in lead aVR; and variable in leads III, aVL, aVF, V1, and V2. Thus, T-wave inversions in leads V1 and V2 may be fully normal. A variety of clinical syndromes can cause T-wave.

WebJul 28, 2024 · T wave: This shows the electrical activity involved in the heart’s ventricular repolarization. This means it shows the electrical reset of the heart as it prepares for the next cardiac cycle. WebIsolated T wave inversion in lead aVL had a sensitivity of 9.8%, specificity of 86.9%, positive predictive value of 30.8% and negative predictive value of 61.7% for predicting MLAD lesions. These diagnostic values did not change materially when focusing on patients with MLAD lesion as the cause.
WebDec 22, 2024 · Normal T waves are upright in leads I, II, and V3-V6, inverted in AVR.
