National Telemetry Association Cardiac Arrhythmia Exam Questions and Answers Rated A+ What is the definition of a cardiac arrhythmia? A cardiac arrhythmia is any irregularity in the normal rhythm of the heart, which can manifest as a faster, slower, or irregular heartbeat. How is atrial fibrillation different from ventricular fibrillation? Atrial fibrillation involves irregular electrical activity in the atria, often leading to a rapid and erratic heart rate. Ventricular fibril...

Telemetry Strips Questions and Answers Rated A+ What is the first step in analyzing a telemetry strip? The first step is to identify the rhythm, which involves examining the P waves, QRS complexes, and T waves to assess the heart’s electrical activity. What is an abnormal finding when analyzing a telemetry strip? An abnormal finding can be an irregular rhythm, such as ventricular fibrillation, or the presence of premature beats, which may indicate arrhythmias or other heart issues...
