T-vector direction differentiates postpacing from ischemic T-wave inversion in precordial leads.
BACKGROUND Postpacing precordial T-wave inversion (TWI), known as cardiac memory (CM), mimics ischemic precordial TWI, and there are no established ECG criteria that adequately distinguish between the two. On the basis of CM properties (postpacing sinus rhythm T vector approaching the direction of the paced QRS vector), we hypothesized that CM induced by right ventricular pacing would manifest ...
متن کاملAngiocardiographic findings in patients with biphasic T-wave inversion in precordial leads.
OBJECTIVE To determine the angiocardiographic findings in patients with unstable angina showing biphasic inversion of T-waves in precordial leads on electrocardiogram, commonly referred to as the Wellen's syndrome. METHODS The descriptive, cross-sectional study was carried out at the National Institute of Cardiovascular Diseases, Karachi, between February and November, 2010. Using convenience...
متن کاملGiant Precordial T Wave Inversion in a Patient with Gastroenteritis
Giant precordial T wave inversion (GPTI) on ECG may be the result of several pathologies, including myocardial ischemia, pulmonary edema, pulmonary embolism, subarachnoid hemorrhage, apical hypertrophy, and postpacing. We describe a case of a 75-year-old woman who developed GPTI after an episode of gastroenteritis. To our knowledge, this is the first report of this ECG pattern associated with g...
متن کاملTall Upright T Waves in the Precordial Leads By IVAN
One hundred ten cases of T waves more than 10 mm in height in the precordial leads were studied. The T waves were wide in ischemic heart disease and thin and peaked in uremia. Marked changes in the ventricular gradient were obselved in ischemic heart disease and in uremia with hyperkalemia. In other conditions, the changes in the ventricular gradient were of a lesser degree. In cases of left ve...
