Heart palpitations are characterized by a fluttering, pounding, or racing sensation in the chest. This can be accompanied by a rapid heartbeat, shortness of breath, dizziness, lightheadedness, or fainting.

Both symptoms can be triggered by stress, anxiety, caffeine, nicotine, or underlying heart conditions. If you experience persistent or severe heart palpitations or racing, it is important to seek medical attention to determine the underlying cause. **
