Cardiac-Vascular Nursing Practice Exam 2026 – Complete Prep Guide

Atrial fibrillation (AF) is characterized by an irregular and often rapid heart rhythm. One of the hallmark symptoms that many patients experience is palpitations. This sensation arises from the chaotic electrical activity in the atria, leading to disorganized contraction of the heart chambers. Patients often describe palpitations as a fluttering or a racing heartbeat, which can be alarming and is directly related to the nature of AF.

While symptoms such as shortness of breath, chest pain, and dizziness can also occur in patients with atrial fibrillation, palpitations are significantly more prevalent and often serve as the first noticeable symptom leading individuals to seek medical attention. The presence of palpitations is not only common but is a key feature that helps differentiate AF from other arrhythmias. Understanding this connection helps healthcare providers recognize atrial fibrillation more effectively, guiding appropriate management and treatment.
