Palpitation generally refers to irregular and rapid heartbeats and can arise for a multitude of reasons. It can be caused by certain harmless conditions, such as strenuous exercise, lack of sleep, stress, anxiety, fear, etc., or it can be an alarming indication of certain illnesses relating to the heart, such as cardiac arrhythmia, which involve changes in heart rate and the contraction pattern. It can give the sensation that the heart has skipped, stopped, or added an extra beat, making us more aware of our heartbeat. Heart palpitations can become a significantly diagnosable characteristic in persons already diagnosed with heart failure or defective heart valves.
