Examining the T wave in leads V5 to V6 can be helpful, as well. AV heart blocks might turn into higher degree AV heart blocks if theyre left untreated. Note: Cabrera’s sign and Chapman’s sign have also been used to diagnose acute MI in the setting of a LBBB. This patient just made 1 mm ST segment elevation in lead V5 and about 0.5 mm ST elevation in V6 - an ECG indeed from a patient with an acute left anterior descending thrombosis. Criteria #3 is under debate as to its usefulness therefore, either criteria 1 or criteria 2 are essentially required.
