WebAug 29, 2024 · Anterior T-wave inversion (TWI) is the most frequent ECG abnormality in ARVC. While anterior TWI is often accompanied by other abnormalities in ARVC, it is usually isolated in young healthy individuals. When anterior TWI is preceded by J-point elevation ≥0.1 mV, the likelihood of ARVC is extremely low, but the absence of this … WebAug 29, 2006 · A 52-year-old woman presented to the emergency department complaining of atypical chest and epigastric pain. Although her neurological examination was completely normal, her ECG revealed deep, symmetric T-wave inversions in all vascular distributions, consistent with neurogenic T waves ().Fifty minutes after the initial ECG, the patient …
