Question

For which of the following types of heart block should an EKG technician observe the patient for signs and symptoms of decreased cardiac output that could lead to cardiac arrest?

1) First degree AV block
2) Second-degree AV block, Mobitz I
3) Second degree AV block, Mobitz II
4) Third degree AV block

Answer 1

An EKG technician should observe the patient for signs and symptoms of decreased cardiac output that could lead to cardiac arrest in a third-degree AV block.

Step-by-step explanation:

The type of heart block for which an EKG technician should observe the patient for signs and symptoms of decreased cardiac output that could lead to cardiac arrest is Third-degree AV block. A third-degree AV block is a complete block where there is no correlation between atrial activity (the P wave) and ventricular activity (the QRS complex). This can result in a significantly decreased heart rate and impaired cardiac output, which can be life-threatening.
