Palpitations facts

• Palpitations can occur without heart disease or as a result of abnormal heart rhythms (arrhythmias).
• The SA node is the natural pacemaker of the heart.
• Slow heart rhythms are called bradycardias. Rapid heart rhythms are called tachycardias.
• The average normal heart beats at a rate of 60 to 100 times per minute.
• Some patients with arrhythmias have no symptoms while others can have symptoms, such as palpitations, dizziness, shortness of breath, or chest pain.
• Arrhythmias can occur because of disease of the heart muscle, valves, electrical system, or arteries to the heart (coronary arteries).
• Palpitations can be evaluated with testing, such as blood tests, echocardiogram, EKG, Holter monitor, treadmill testing, and tests of the coronary arteries.
• Palpitations can be relieved in many patients by stress reduction, quitting smoking, and reduction of caffeine and alcohol.
