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. Most of the time, palpitations are harmless and can be caused by factors such as caffeine, anxiety, or certain medications. However, if palpitations are frequent or accompanied by other symptoms like chest pain or shortness of breath, it may indicate an underlying issue with the heart, such as arrhythmia or heart disease. Consulting a healthcare professional is advisable for proper evaluation and management.
