Palpitations

 Hadith:

Narrated Al-Bara 'bin `Azib:

The Prophet said to me, "Whenever you go to bed perform ablution like that for the prayer, lie or your right side.

 

The Study

A palpitation is an increased awareness of the normal heart beat or the sensation of slow or rapid heart rate or an irregular heart rhythm. The normal heart beat is sensed when the patient is anxious, excited, exercising, or lying on the left side. The most common arrhythmia’s to be felt as palpitations are premature ectopic beats and paroxysmal tachycardia's.

 

The commonest cause is anxiety. Most normal people have experienced palpitations briefly as a result of an alarming experience such as narrow escape from an accident. More prolonged emotional disturbances more common in the anxious but, once the palpitation has developed, it can readily induce further anxiety by arousing suspicions of heart disease in the patient’s mind. Thus a vicious circle is closed and Da Costa’s Syndrome results. In anxiety the mechanism of the palpitation is an increase in the force of cardiac contractions, often combined with tachycardia; both are mediated via catecholamine release. Palpitation as a whole can be considered according to whether it is due to an increase in the force, or more precisely in the type, of contraction or to a change in the type, of contraction or to a change in the rate or rhythm of the heart.

Palpitation is a feature of a group of cardiac lesions, which have in common an increase in the output of one or other ventricle. Thus, in aortic regurgitation, mitral regurgitation, atrial and ventricular septal defects, and persistent ducts arteriosus, a complaints of palpitation is common. This is not the case, however, in uncomplicated mitral stenosis, hypertension and ischaemic heart disease in which palpitation, if present is due to superadded anxiety and not to the cardiac lesion itself. High – output states, in general, are also causes of palpitation which, as in the case of anxiety, is due both to the increase in the force of contraction and to tachycardia. In thyrotoxicosis, particularly, palpitation is a very common symptom but it may also be a feature of severe anaemia, arteriovenous fistula, beriberi and corpulmonale.

Catecholamine release as cause of palpitation has already been mentioned. This particularly prominent in phaeochromacytoma; both adrenaline and no r adrenaline, but particularly the former, increase the force of ventricular contraction. Adrenaline also causes tachycardia but the release of nor adrenaline, causing a sharp rise in blood pressure

 

Comment

Since the palpitation occurs during stress or exercised which are reflex to abnormal situation which are related to hormonal effect or hyper activity of

nervous system also we should say the lying in the left side has some thing related to either hormonal or nervous system abnormality or both.
