Arrhythmia, also known as cardiac arrhythmia or heart arrhythmia, is a group of conditions in which the heartbeat is irregular, too fast, or too slow.[2] The heart rate that is too fast – above 100 beats per minute in adults – is called tachycardia, and a heart rate that is too slow – below 60 beats per minute – is called bradycardia.[2] Some types of arrhythmias have no symptoms.[1] Symptoms, when present, may include palpitations or feeling a pause between heartbeats.[1] In more serious cases, there may be lightheadedness, passing out, shortness of breath or chest pain.[1] While most types of arrhythmia are not serious, some predispose a person to complications such as stroke or heart failure.[2][3] Others may result in sudden death.[3]
There are four main groups of arrhythmia: extra beats, supraventricular tachycardias, ventricular arrhythmias and bradyarrhythmias.[3] Extra beats include premature atrial contractions, premature ventricular contractions and premature junctional contractions.[3] Supraventricular tachycardias include atrial fibrillation, atrial flutter and paroxysmal supraventricular tachycardia.[3] Ventricular arrhythmias include ventricular fibrillation and ventricular tachycardia.[3][7] Arrhythmias are due to problems with the electrical conduction system of the heart.[2] Arrhythmias may also occur in children; however, the normal range for the heart rate is different and depends on age.[3] A number of tests can help with diagnosis, including an electrocardiogram (ECG) and Holter monitor.[5]
