Question

STEMI is characterized by:

A) ST-segment elevation in 2 or more contiguous leads OR new LBBB
B) Ischemic ST-segment depression greater than or equal to 0.5mm OR dynamic T-wave inversion with pain or discomfort
C) Nondiagnostic changes in the ST segment or T-wave
D) Nonpersistent/transient ST elevation greater than or equal to 0.5mm for less than 20 minutes

Answer 1

STEMI is characterized by ST-segment elevation in 2 or more contiguous leads on an ECG. This indicates severe obstruction in the coronary arteries and is usually indicative of a heart attack.

Step-by-step explanation:

STEMI is characterized by ST-segment elevation in 2 or more contiguous leads. This means that there is a visible increase in the height of the ST segment on an electrocardiogram (ECG) in multiple leads that are next to each other. This is an important diagnostic criteria for a STEMI, as it indicates severe obstruction in the coronary arteries and is usually indicative of a heart attack.
