More than 5 million Americans are estimated to suffer from atrial fibrillation, or A-fib. In A-fib, the heart’s upper chambers—known as atria—send abnormal electrical signals to the lower chambers, or ventricles, creating a fast and irregular heart rhythm (fibrillation) that leads to poor blood flow through the body. Symptoms may include: • Weakness or lightheadedness • Shortness of breath • Palpitations or heart racing Causes may include: • High blood pressure • Coronary artery disease • Heart attack • Heart valve disease Find out how NorthShore Cardiovascular Institute experts can help control A-fib through advanced surgical and nonsurgical procedures at northshore.org/r15.
