Certified EKG Technician (CET) Practice Exam 2025 – Comprehensive Test Prep

In cases of third-degree AV block, it is crucial for the technician to monitor for signs of decreased cardiac output. This condition, characterized by a complete dissociation between atrial and ventricular activity, may lead to inadequate blood flow being pumped throughout the body. As a result, patients may experience symptoms such as dizziness, fatigue, and syncope due to insufficient perfusion of vital organs.

Monitoring for decreased cardiac output is essential because it can indicate that the heart is not effectively meeting the body's demands, which may necessitate urgent medical intervention. Vigilance in observing for these signs can help in recognizing the need for potential treatments, such as pacing.

The focus on detecting decreased cardiac output is particularly relevant in third-degree AV block, where the risk of bradycardia and subsequent heart failure increases. Understanding these dynamics helps ensure appropriate and timely responses to patient needs in the context of this arrhythmia.
