==Overview==
 
[[Palpitations]] may be classified based on [[cause]], [[duration]], [[rhythm]] and clinical presentation.

==Classification==
People describe their palpitations in many different ways, but there are some common patterns:
===The Heart "Stops"===
Those who experience palpitations may have the feeling that their heart stops beating for a moment, and then starts again with a "thump" or a "bang". Usually this feeling is actually caused by an extra beat (premature beat or [[extrasystoles|extrasystole]]) that happens earlier than the next normal beat, and results in a pause until the next normal beat comes through. People are not usually aware of the early, extra beat, but may be aware of the pause, which follows it (the heart seems to stop). The beat after the pause is more forceful than normal, giving the "thumping" sensation.
===The Heart is "Fluttering" in the Chest===
Any rapid heartbeat (or [[tachycardia]]) can give rise to this feeling. A rapid, regular fluttering in the chest may be associated with sensation of pounding in the neck as well, due to simultaneous contraction of the upper, priming chambers of the heart (the [[atria]]) and the lower, main pumping chambers (the [[ventricles]]). If the fluttering in the chest feels very irregular, then it is likely that the underlying rhythm is [[atrial fibrillation]]. During this type of rhythm abnormality, the atria beat so rapidly and irregularly that they seem to be quivering, rather than contracting. The ventricles are activated more rapidly than normal (tachycardia) and in a very irregular pattern.
===Feelings of Anxiety or Panic===
Palpitations may be associated with feelings of anxiety or panic. It is normal to feel the heart thumping when feeling terrified or scared, but it may be difficult to know whether the palpitations or the panicked feeling came first. Unfortunately, since it can take some time before a clear diagnosis is made in a patient complaining of palpitations, people are sometimes told initially that the problem is anxiety.


Stressful situations cause an increase in the level of stress hormones, such as [[adrenaline]], circulating in the blood, and there are some types of abnormal heart rhythm that can be stimulated by adrenaline excess, or by exercise. It may be possible to diagnose these sorts of palpitations by performing simple tests, such as an exercise test, while monitoring the [[ECG]].

===Changes in Posture===
*#[[Cardiac]] -[[Arrhythmia]] related
Some types of abnormal heart rhythm seem to be affected by posture. For many people, standing up straight after bending over can provoke a rapid heart rate. Often these attacks can be abolished again by lying down. Many people, if not all, are more aware of the heartbeat when lying quietly in bed at night. This is partly because at that time, the attention is not focused on other things, but also because the slower heart beat at rest can allow more premature beats to occur.

*Based on '''[[duration]]''', [[palpitation]] may be classified as :
*#[[Persistent]] or [[sustained]]
*#[[Poorly sustained]]/ [[short lasting]]
*Based on '''[[rhythm]]''', [[palpitation]] may be classified as :
*#[[Regular]]
*#[[Irregular]]
*[[Extrasystolic]] [[palpitation]] is often described as missed beats which are sudden in [[onset]] and occur at rest.
*[[Tachycardiac]] [[palpitation]] are often described as a [[fluttering sensation]] in the chest which is sudden in [[onset]].  
**[[Tachycardic]] [[palpitation]] include [[ventricular]] [[tachycardias]], [[AV re-entry tachycardia]], [[AN Nodal re-entry tachycardia]], [[atrial fibrillation]], [[atrial tachycardias]] and [[atrial flutter]].
**It is associated with a [[regular]] or [[irregular]] increase in [[heart rate]] and [[symptoms]] such as [[syncope]], [[chest pain]], [[breathlessness]] and neck pulsations.
*[[Anxiety]] related [[palpitation]] as the name suggest are mostly seen in individuals with [[generalized anxiety disorder]] and are gradual in [[onset]].
**It is associated with an increase in [[heart rate]] and [[symptoms]] such as a ‘lump-like’ [[sensation]] in the throat and tingling sensations in the hands and face.
*Patients experiencing a [[pulsation]] type of palpitation often feel like their [[heart]] is pounding.
**This [[sensation]] is gradual in [[onset]], triggered by [[exertion]] and may be associated with [[asthenia]].
