Arrhythmia is a general term for any heart rhythm that is abnormal. Abnormal heart rhythms include a heart beating too fast, too slow or irregularly/inconsistently. Arrhythmias occur when the heart’s electrical conduction system is not working properly and can occur at any age. There are many different types of arrhythmias, some of which do not affect your overall health, however, some can be life-threatening. They can be associated with symptoms, including palpitations (an awareness of your heart beat), dizzy spells and shortness of breath, or you may not notice anything abnormal. Treatment for an arrhythmia depends on its type and how much it is affecting your health and daily life. Some treatments include medications, removing rhythm-altering triggers, lifestyle changes (i.e. diet and exercise) or ablation.
