Irregular heartbeat
It’s not unusual for your heart to race once in a while, especially when you’re nervous or excited. Also, it’s not unusual to skip or add a beat once in a while. But if you’re feeling that your heart is beating out of time more than just once, and it happens regularly, you should let your doctor know.
In most cases, it might be caused by something that’s easy to fix, such as too much caffeine or not enough sleep. But sometimes, it can be a sign of a condition called atrial fibrillation, that requires treatment, so it’s best to consult with your doctor.
