T-wave inversion in the aVL lead is associated with severity of stenosis in the LAD artery
Background & Aims: The clinical value of T wave inversion (TWI) in the lead aVL in diagnosing coronary artery disease (CAD) remains unclear. Hence, we aim to evaluate the association between TWI in the aVL lead and the severity and location of coronary artery stenosis in elective coronary angiography. Material and Method: Electrocardiograms (ECGs) of 167 consecutive patients undergoing electiv...
متن کاملIsolated T Wave Inversion in Lead aVL: An ECG Survey and a Case Report
Background. Computerized electrocardiogram (ECG) analysis has been of tremendous help for noncardiologists, but can we rely on it? The importance of ST depression and T wave inversions in lead aVL has not been emphasized and not well recognized across all specialties. Objective. This study's goal was to analyze if there is a discrepancy of interpretation by physicians from different specialties...
متن کاملThe neglected lead on electrocardiogram: T wave inversion in lead aVL, nonspecific finding or a sign for left anterior descending artery lesion?
BACKGROUND The electrocardiogram (ECG) is the most important diagnostic tool for acute myocardial infarction (AMI). T wave inversion (TWI) in lead aVL has not been emphasized or well recognized. OBJECTIVE This study examined the relationship between the presence of TWI before the event and mid-segment left anterior descending (MLAD) artery lesion in patients with AMI. METHODS Retrospective ...
متن کاملSignificance of asymmetrically inverted T wave.
Two consecutive series of patients with a T wave asymmetry ratio of 2.0 or greater have been studied. Patients with bundle-branch block or who were on digoxin or a similar drug were excluded. In 50 of the 69 patients, the heart was examined either by echocardiography or by direct inspection. Sixty-one of the 69 patients had diseases commonly associated with left (or right) ventricular hypertrop...
متن کاملThe dominant T wave and its significance.
INTRODUCTION The shapes of the T waves as observed in different leads placed on the thorax are very similar. The dominant T wave is introduced as a means to characterize this general signal shape. Its relationship to the transmembrane potentials of cardiac myocytes is discussed. METHODS AND RESULTS The source description of a biophysical model that previously was shown to yield realistic T wa...
