What is the goal of a diagnostic EPS?

• A. Assessing the function of the cardiac conduction system.
• B. Observing for dysfunction or anomalies that may contribute to arrhythmia.
• C. Assessing the function of the cardiac conduction system and observing for dysfunction or anomalies that may contribute to arrhythmia.
• D. Measuring blood pressure during exercise.

Answer: (C)

The goal of a diagnostic EPS is to map how the heart’s electrical system conducts impulses and to actively look for dysfunctions or anomalies that could support or trigger arrhythmias. By recording intracardiac signals and sometimes inducing arrhythmias, clinicians can identify reentrant circuits, accessory pathways, or other substrates and understand how the conduction system behaves under stress. This dual aim—evaluate conduction function and observe for abnormalities—is why the combined option fits best. Measuring blood pressure during exercise isn’t part of diagnostic EPS.
