A rising number of Americans are being detected with some form of coronary disease every year. Factors such as stress, diet and lack of exercise are the biggest risk factors that contribute to cardiovascular disease.

These are generally unpleasant and characterized by irregular beating of the heart. Heart palpitations symptoms are quite infrequent and do not last longer than few seconds.

What are the types of Heart Palpitations?

Cardiac palpitations are also referred to as arrhythmias. It is either too slow or too fast and irregular in nature and gives an unpleasant feeling to the patient.

    * Very rapid arrhythmias- In this case, the patient's heart beats greater than 100 times in a minute and it is referred to as tachycardia.

    * Fibrillations- The rhythms that are irregular in nature are known as fibrillations.
    * Premature contraction- In this case, the heart beats earlier than a normal heartbeat. This results in the feeling of forceful heartbeat.
