![]() Possible causes include heart disease, aging, myocardial ischemia (reduced blood flow to heart muscle), electrical conduction disorders, stress, caffeine, tobacco, alcohol, diet pills, and cough medication. It is not always clear what causes an arrhythmia. ![]() The majority of these operations have been performed in conjunction with other cardiac procedures (such as valve repair or coronary bypass), but the procedure can also been used for atrial fibrillation as the sole indication. The Columbia team has performed surgical atrial fibrillation ablation (SAFA) in more than 600 patients, with a success rate (normal rhythm) at 6-12 months of 76%. While nonsurgical treatment options, such as electrical cardioversion, often help restore a normal rhythm initially, recurrence rates as high as 75% have been reported.Ĭolumbia's surgical atrial fibrillation program is led by Michael Argenziano, MD, Director of Arrhythmia Surgery, and the management team are trained in the most innovative treatment options for atrial fibrillation. These risks warrant medical attention for patients with AF even if symptoms are mild. AF is also associated with increased risk of congestive heart failure and cardiomyopathy (heart muscle disease). If a blood clot moves to an artery in the brain, AF can lead to stroke. In addition, AF occurs in as many as 50% of patients undergoing cardiac operations.Ībnormalities in the heart's electrical impulses in patients with AF cause blood to be pumped improperly, resulting in pooling or clotting. It is one of the most common forms of cardiac arrhythmia, affecting 0.4% of the general population and 5 to 10% of persons over 65 years of age. Atrial FibrillationĪtrial fibrillation (AF) is a form of arrhythmia, or irregular heartbeat, in which the atria (the two small upper chambers of the heart) quiver instead of beating effectively. Ventricular tachycardia (starting in the ventricles)īradycardia refers to a slow heart rhythm, caused by a failure of the heart signals to fire as they should.Supraventricular tachycardia (starting above the ventricles).Atrial tachycardia (starting in the atria).There are three major types of tachycardia: Tachycardia is defined by a heart rate over 100 beats per minute. The two major types of heart arrhythmia are tachycardia (fast arrhythmia) and bradycardia (slow arrhythmia). Atrial fibrillation (AF) is a form of arrhythmia, or irregular heartbeat, in which the atria (the two small upper chambers of the heart) quiver instead of beating effectively. A heart block (delay in the normal flow of electrical impulses that cause the heart to beat) may be present.Īny of these may cause the heart to skip a beat, beat too fast, or beat too slow. ![]() The sinus node may develop an abnormal rate or rhythm.The heartbeat may begin in a part of the heart other than the sinus node.An arrhythmia may happen for different reasons: ![]() There are several types of arrhythmias, named by the chambers of the heart in which they occur (atria or ventricles) and by what effect they have on the heart's rhythm.

They may also use an electrocardiogram (ECG or EKG) to see if the heart is functioning properly. If necessary, the doctor may order blood tests to examine electrolyte, hormone, or thyroid levels. If heart palpitations are not occurring at the time of the examination, the doctor may ask the individual to tap out the rhythm of the palpitations that they usually experience. They will also check the person’s vital signs, including blood pressure and pulse rate, and listen to their heart through a stethoscope. what their social and dietary habits involve, such as caffeine and alcohol consumption, exercise, sleep, and drug and medication use.what their family health history includes.whether there are other symptoms, such as fainting, pain, or lightheadedness.whether the symptoms begin slowly or suddenly.how old the person was when symptoms began.A doctor will take a detailed medical history and perform a physical examination as part of the diagnostic process.
