What is the significance of biphasic T waves? - Steady. Health

WebDec 30, 2006 · 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. WebAn ECG done in the ER showed biphasic T waves in leads V2 and V3 (Figure 2), raising the concern for Wellens' syndrome.

WebMethods: One thousand four hundred thirty-five ECGs were randomly selected to determine the incidence and gender frequency in tracings showing positive (PPV 2 ), and biphasic (BPV 2 ) P waves in V 2 , as well as NPV 2 . To those cases with NPV 2 , 84 cases with that anomaly from earlier archived ECGs were added to give a larger group for analysis. WebDiagnosis [ edit] The diagnosis is done via: [citation needed] Progressive symmetrical deep T wave inversion in leads V2 and V3 Slope of inverted T waves generally at 60°-90° … WebLeft atrial enlargement is suspected if the duration of the P-wave is prolonged, especially if the P-wave is two-humped in lead II and clearly biphasic in lead V1.
