Because procainamide degrades conduction and often causes hypotension, the clinical end-points to loading patients with procainamide are:

2. when clinically significant hypotension occurs

3. when the QRS widens 50% from it's pre-treatment width

4. when approximately 1 gram has been administered

The best answer is: true

The most recent Guidelines repeatedly call for early 12-lead ECG analysis for treating patients with acute coronary syndrome symptoms, emphasizing the use of pre-hospital 12-lead ECG by EMS personnel.

The best answer is: ventricular fibrillation

The best answer is: b. false
