1. ST-segment elevation
2. loss of P waves
3. bradycardia
4. widening of the QRS complex
Correct Answer: 1
The electrocardiogram reflects changes in conduction due to myocardial ischemia and necrosis. Classic ECG changes seen in acute myocardial infarction include ST-segment elevation. Loss of P waves occurs with atrial flutter and fibrillation. Bradycardia can be a normal or abnormal rhythm. Widening of the QRS complex occurs with bundle branch block.
