Palpitations are the sensation of feeling your heart beating rapidly, fluttering, or pounding. They can occur during physical activity, stress, or even while at rest. While often harmless, they can sometimes indicate an underlying health issue, such as arrhythmia or anxiety. Common triggers for palpitations include caffeine, nicotine, and certain medications. Most people experience them occasionally, and they usually resolve on their own. However, if palpitations are frequent or accompanied by symptoms like chest pain or shortness of breath, it is important to consult a healthcare professional for further evaluation.
