Certified Cardiographic Technician (CCT) Practice Exam 2025 - Free CCT Practice Questions and Study Guide

When a patient develops a first-degree AV block during a stress test, the appropriate course of action is to continue the test while monitoring the rhythm closely. First-degree AV block is characterized by a prolongation of the PR interval on the ECG but does not typically indicate a significant risk to the patient or require immediate cessation of the test.

In this scenario, first-degree AV block is often considered a benign finding, especially in the context of stress testing. The technician should remain vigilant, observing any changes in the patient’s condition or rhythm, as alterations could indicate the onset of more serious conduction abnormalities that would necessitate stopping the test. However, since first-degree AV block alone is generally not life-threatening, it is acceptable to continue the test under careful supervision.

The other options suggest either stopping the test or reducing its intensity, which do not align with the guideline for managing first-degree AV block and would not allow for the assessment of the patient's response to stress in a controlled manner.
