Palpitations are feelings that your heart is skipping a beat, fluttering, or beating too hard or too fast. You may have these feelings in your chest, throat, or neck. They can occur during activity or even when you're sitting still or lying down.
These factors make the heart beat faster or stronger than usual, or they cause occasional premature (extra) heartbeats. In these situations, the heart is still working normally, and the palpitations usually are harmless.
Sometimes palpitations are symptoms of an arrhythmia. An arrhythmia is a problem with the rate or rhythm of the heartbeat. Some arrhythmias are signs of heart conditions, such as heart attack, heart failure, heart valve problems, or heart muscle problems. However, less than half of the people who have palpitations have arrhythmias.
People can reduce or prevent palpitations by avoiding things that trigger them (such as stress and stimulants) and treating related medical conditions.
