What is a common symptom of arrhythmia?

Dizziness is a common symptom of arrhythmia because it can result from the heart not pumping blood effectively or at a regular rate. When the heart beats irregularly or too fast/too slow, the brain may not receive an adequate blood supply, leading to feelings of lightheadedness or faintness. This symptom can vary in intensity depending on the severity and type of the arrhythmia, but it is often one of the first indicators that someone is experiencing an abnormal heart rhythm.

In contrast, increased blood pressure is not a direct symptom of arrhythmia; while some arrhythmias may cause fluctuations in blood pressure, they are not typically characterized by a consistent increase in blood pressure. Enhanced heart elasticity is not a symptom of arrhythmia but rather a feature of healthy heart function. A regular heartbeat, on the other hand, signifies normal heart rhythm, contradicting the notion of arrhythmia. Therefore, dizziness stands out as a key symptom associated with abnormal heart rhythms.
