The heart has a natural “pacemaker” and conduction system that works to direct and coordinate the contraction of the upper chambers (the atria) and lower chambers (the ventricles) of the heart. This system works in a careful sequence to ensure that blood is pumped efficiently through the heart. When the natural pacemaker or the conduction system are not working properly, or when extra signals arise, this can result in fast, slow, or erratic heart beats. These abnormal heart rhythms can cause symptoms such as palpitations, dizziness, or blacking out.
Common contributing factors to developing arrhythmias include age, heart attacks/coronary artery disease, valve disorders, and heart surgery.
Your electrophysiologist may order different tests to determine the cause of your arrhythmia. The test results will dictate the best treatment options. It may be treated with lifestyle changes or medications.
If the arrhythmias cannot be treated by lifestyle changes or medications then an invasive procedure may be required. The invasive procedures may include an ablation, pacemaker or defibrillator.
