T-wave inversion T-wave corresponds to the phase of rapid repolarization of the ventricular action potential. In the 12-lead ECG of adults, the normal T-wave is inverted in aVR; upright or inverted in leads aVL, III, and V1; and upright in limb leads I, and II, and in V3 to V6...
II、III、avF、V1-4导联T波倒置,V5导联T波双向。心电图诊断:1.窦性心律 2.T波改变。 心电图解析: T波改变是常见的心电图诊断之一,其形成机制和表现形式多种多样。本图T波倒置主要体现在V1-4,需鉴别下面几种常见原因。 儿童右室优势,Tv1-2倒置,部分可波及V3...
On arrival, his pain had resolved, and his 1st ECG showed inverted/biphasic T-waves in lead III and aVF and a tall T wave in V2-V3. Three- and one-half hours after arrival, his chest pain returned and his ECG showed an inferior-posterior STEMI. Why should an emergency physician be ...
T‐wave inversion (TWI) is defined as negative T‐wave of ≥1 mm in depth in two or more contiguous leads, with exclusion of leads aVR, III, and V1.[1]The presence of TWI at 12‐lead electrocardiogram (ECG)...
