EKG Practice Test 1

This EKG practice test is designed to help you learn to recoginze all of the EKG rhythms that you will encounter during emergencies and during the AHA ACLS provider course.  Use these EKG practice tests to help you become proficient in your rapid rhythm identification.

      This would be considered sinus rhythm with a first-degree heart block.
      This is first-degree heart block. For first-degree heart block, the rhythm is regular. The PR interval will be prolonged at > 0.2. The QRS complex will usually be normal. First-degree heart block indicates slowed but not blocked conduction through the AV node.
      Kind regards,

    The strip in question 11 has an irregular R-to-R interval, yet it is labeled as third degree heart block. Assuming this is a six-second strip, the ventricular rate is also higher than I would expect from an impulse that originates in the ventricle(s). Could someone please explain?

    Also for #9, while I do see how this could be mobitz type II, to ensure this was an accurate identification, a longer strip would be needed. Although the PR interval does increase, one could easily argue this was complete/3rd degree as well. While the first and second QRS complex do have an increase in PR interval, it could easily be argued that the P-P interval without accompanying QRS complexes are consistent, the P wave may be buried in the 3rd QRS complex. I am not saying that this is not an example of mobitz type II, don’t get me wrong. However, every ACLS course I have ever attended has the classical demonstration of longer longer longer drop, where this is ~ regular PR to VERY increased PR then a “drop” followed by a QRS without a discernible P wave. So nit picking, and I do appreciate the practice quiz for free. But I do believe a better example could be provided, as again without a longer lead this is debatable.

    For # 12, while agreed it should be treated as v-fib, in the ten sessions of ACLS I have experienced, this question would typically not be “Identify the rhythm” without context, more like how would you treat this. If it were to say with a pulse, or without a pulse, this would be different, although the examples of PEA given in ACLS typically look as though they are NSR without a pulse, this (in my opinion) would be a better substitute.
