Those with an irregular heartbeat are often treated with blood thinners to reduce the risk of complications. Pacemakers are often used for slow heart rates. This latter group may have more significant side effects, especially if taken for a long period of time. Medications for a fast heart rate may include beta blockers, or antiarrhythmic agents such as procainamide, which attempt to restore a normal heart rhythm. Treatments may include medications, medical procedures such as inserting a pacemaker, and surgery. Many arrhythmias can be effectively treated. A number of tests can help with diagnosis, including an electrocardiogram (ECG) and Holter monitor. Arrhythmias are due to problems with the electrical conduction system of the heart. Bradyarrhythmias are due to sinus node dysfunction or atrioventricular conduction disturbances. Ventricular arrhythmias include ventricular fibrillation and ventricular tachycardia. Supraventricular tachycardias include atrial fibrillation, atrial flutter and paroxysmal supraventricular tachycardia. Extra beats include premature atrial contractions, premature ventricular contractions and premature junctional contractions. Īrrhythmias are often categorized into four groups: extra beats, supraventricular tachycardias, ventricular arrhythmias and bradyarrhythmias. While most cases of arrhythmia are not serious, some predispose a person to complications such as stroke or heart failure. In more serious cases, there may be lightheadedness, passing out, shortness of breath, chest pain, or decreased level of consciousness. Symptoms, when present, may include palpitations or feeling a pause between heartbeats. Some types of arrhythmias have no symptoms. A resting heart rate that is too fast – above 100 beats per minute in adults – is called tachycardia, and a resting heart rate that is too slow – below 60 beats per minute – is called bradycardia.
