The parietal pericardium is the

This AV block has a consistent PR interval and normal QRS complexes, but occasionally “drops” a QRS complex. 

A premature beat originating in the atria is a(n):

Your patient is in ventricular tachycardia with a rate of 160. The only complaint is weakness and dizziness. What would be the most appropriate treatment at this time?

A 42 year old patient complains of substernal chest pain radiating into their jaw and unrelieved by rest.  Their pain is an 8/10 and they report no previous cardiac history.  Their pulse is regular and their ECG is normal. Vitals HR 100, BP 130/80, SpO2 98%, RR 24. Select the most appropriate treatment plan.

If you determine what you see on the ECG is a wandering atrial pacemaker rhythm with a rate of 70 suddenly accelerates to a rate of 120, now the rhythm should be called:

You observe an ECG with a regular rate at 88. There is a round upright p wave before every QRS, a PRI of .12, and a normal QRS complex of .08 seconds. What is this rhythm?

Match the following premature ventricular contraction term to its definition.

You are assisting a patient in getting into his vehicle, and you note his right posterior calf is warm, reddened, and edematous.  The left leg is normal.  Posterior tibialis pulses are present and equal bilaterally.  You suspect:

You’ve achieved ROSC with an adult patient. You note a blood pressure of 70/48 and sinus tachycardia at 130. After securing airway and oxygenation you should
