What are heart palpitations?
Heart palpitation is the feeling of the heart beating faster than normal. A person can experience heart palpitations irrespective of his health state – someone not affected by cardiovascular diseases can also feel them. Even when one’s heart is beating normally, or slightly faster than usual, one might feel palpitations.
Most palpitations are not harmful and stop on their own. Some palpitations might, however, be signs of an unhealthy heart.
Causes of heart palpitations other than those related to heart diseases
Anxiety, fear, stress can all cause heart palpitations. People experiencing panic attacks may have this feeling.
Vigorous physical exercise
When engaging in intense exercise, one may have the feeling that the heart is feeling faster and harder than normal, though it is but normal.
The following medical conditions can lead to the heart beating faster or stronger:-
- An overactive thyroid

Palpitations related to heart problems
Heart diseases include problems with the rate of rhythm of the heartbeat known as arrhythmias. The heart beats too fast or too slow or irregularly.
Palpitations are more likely to be related to an arrhythmia if the person:

- Has coronary heart disease (CHD) or risk factors for CHD.
- Has other heart problems, such as heart failure.
