Cardiac arrhythmia open access journals also known as cardiac arrhythmia or heart arrhythmia is a group of conditions in which the heartbeat is irregular, too fast, or too slow. 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.Some types of arrhythmias have no symptoms. Symptoms when present may include palpitations or feeling a pause between heartbeats. In more serious cases, there may be light-headedness, passing out, shortness of breath or chest pain. While most types of arrhythmia are not serious, some predispose a person to complications such as stroke or heart failure. Others may result in sudden death. There are four main groups of arrhythmia: extra beats, supraventricular tachycardia, ventricular arrhythmias and Brady arrhythmias. Extra beats include premature atrial contractions, premature ventricular contractions and premature functional contractions. Supraventricular tachycardia includes atrial fibrillation, atrial flutter and paroxysmal supraventricular tachycardia.
