Palpitations :
Palpitations are generally known as heart racing spells caused by changes in the heart rate and rhythm. This influences the variations in the sounds of heart beat recognizable to pounding, fluttering, skipping a beat or having an additional heart beat.
It can be associated with uncontrollable sweating. Palpitations are routinely noticed when there is fluctuations in anxiety levels, eating habits, emotional triggers, hormonal levels during pregnancy or menstruation or history of underlying heart diseases like abnormal valve or cardiac murmurs. Sometimes excessive or prolonged intake of caffeine products or substance abuse can also cause palpitations.
