Which symptom is often associated with arrhythmias?

Palpitations are a common symptom associated with arrhythmias because they represent the abnormal sensations of heartbeats that individuals may experience due to irregular heart rhythms. When the heart beats too fast, too slow, or in an uncoordinated manner, it can create awareness of the heartbeat, leading patients to describe this sensation as "fluttering" or "racing," often referred to as palpitations. This symptom is particularly noticeable during episodes of arrhythmia and can be alarming for patients, prompting them to seek medical attention.

While other symptoms like fatigue and even headaches can occur in relation to arrhythmias, they are not as directly indicative or characteristic of arrhythmias themselves. Fatigue, for instance, may stem from numerous causes and isn't specific to heart rhythm issues. Similarly, weight gain is typically associated with various health conditions unrelated to arrhythmias. Thus, palpitations stand out as a primary and specific symptom tied to abnormal heart rhythms, providing clear insight into the patient's condition.
