Atrial fibrillation

Atrial fibrillation (A-fib) is an abnormal heart rhythm (arrhythmia) characterized by a rapid rate and irregular rhythm that feels like the heart is quivering. It can lead to chest discomfort, shortness of breath, lightheadedness, and the formation of blood clots, which can cause...

Sick sinus syndrome

Sick sinus syndrome is a condition in which the normal pacemaker of the heart is unable to keep the heart beating at a normal rate or rhythm to deliver blood to the body. Causes include replacement of pacemaker cells with aging, heart disease or heart attack, inflammation or inf...

Premature ventricular contractions

Premature ventricular contractions (PVCs) are extra, abnormal heartbeats that begin in the lower chambers of the heart (ventricles) instead of the upper chambers (atria). Although usually benign, PVCs can present with certain sensatio...

Atrial flutter

Atrial flutter is an arrhythmia, meaning the system that regulates the heartbeat is not working correctly. The upper two chambers of the heart – the atria – beat faster than the lower two chambers and end up quivering, or fluttering, rather than beating.

It can be caused by high blood pressure; coronary artery disease; alcoholism; hyperthyroidism; and a previous case of rheumatic fever, which damages the heart valves.

Symptoms include fast, regular pulse; weakness or faintness; shortness of breath; and sometimes chest pain.

Since the quivering, fluttering atria cannot properly pump out the blood, the blood can stagnate and clot. A clot that travels through the body can cause a stroke. Also, the stagnated blood can cause blood pressure to drop and heart failure can result.

Diagnostic tests may include physical examination; EKG (also known as ECG); x-ray; MRI; and/or long-term monitoring with the patient wearing a Holter monitor.

Treatment first consists of medication to slow the heart rate and prevent blood clots. Defibrillation, catheter ablation, and surgery may also be done, as well as treatment of any underlying disorders.
