Heart rhythm disorders, or cardiac arrhythmias, are abnormal heartbeats that cause the heart to beat too fast (tachycardias), too slow (bradycardias) or irregularly. These disorders are caused by a problem with the heart’s electrical system, which stimulates the heart to squeeze and relax. Although cardiac arrhythmias sometimes occur in a healthy heart and have minimal consequences, they can also be a sign of a more serious problem. Underlying cardiovascular conditions can result in complications, such as stroke or sudden cardiac death – the leading cause of death in the United States.
The Cardiac Arrhythmia Service at the Brigham and Women’s Hospital (BWH) Heart & Vascular Center is devoted solely to the care of patients with irregular heart rhythms, heart palpitations and rapid heartbeats. Treatment is provided by some of the world's most experienced physicians in cardiac electrophysiology (the study of the heart’s electrical system), and many patients with complex cases are referred to our program. Our heart rhythm specialists perform more than 3,000 procedures annually, utilizing the latest medications, devices and innovative care approaches.
Premature (extra) beats, the most common type of arrhythmia, are harmless most of the time and do not require treatment. They often feel like fluttering in the chest.
Supraventricular arrhythmias are tachycardias that start in the atria or atrioventricular (AV) node. Types include:
Ventricular arrhythmias begin in the ventricles, the heart's lower chambers, and often require immediate medical care.
Bradyarrhythmias happen when the heart rate is slower than normal, decreasing blood flow. Fainting can result.
There are a number of factors that may contribute to the development of heart rhythm disorders, including:
A patient with an arrhythmia may experience one or more of the following symptoms:
The symptoms of arrhythmias may resemble other conditions. Consult your doctor for a diagnosis.
Our arrhythmia specialists provide expert evaluation and diagnosis with the aid of the latest in advanced imaging technologies. Along with a careful physical examination, the cardiologist may order one or more of the following tests or procedures:
Specialists in our Cardiac Arrhythmia Service develop individualized treatment plans for patients based on:
It is important to treat an arrhythmia, because the condition can worsen over time as the heart muscles become overworked and weak, making it even more difficult for the heart to function properly. Treatment may involve a number of options, including:
The Heart & Vascular Center is located in the Shapiro Cardiovascular Center, across the street from BWH's main 75 Francis Street entrance. The Heart & Vascular Center brings together the full range of services in one location, fostering seamless and coordinated care for all cardiovascular patients.
If you are having surgery or a procedure, you will likely be scheduled for a visit to the Watkins Clinic for pre-operative information and tests.
The day of surgery, you care will be provided by surgeons, anesthesiologists and nurses who specialize in surgery for patients with heart rhythm disorders. After surgery, you will go to the post-surgical care unit where you will receive comprehensive care by an experienced surgical and nursing staff.
During your surgery, family and friends can wait in the Shapiro Family Center. Staff members will provide surgery updates and caregivers who leave the hospital will be contacted by cell phone.
Patients benefit from the teamwork of cardiologists, cardiac surgeons, cardiovascular imaging experts and radiologists, and anesthesiologists, all experts in heart rhythm disorders. They work alongside nurses, physician assistants, physical therapists, dietitians and social workers to achieve outstanding outcomes for our patients. Learn more about Our Heart & Vascular Team.
