An arrhythmia, or cardiac arrhythmia, is an abnormal heart rhythm. They can present as an irregular heartbeat, bradycardia (slow heartbeat), tachycardia (fast heartbeat), or any combination of these issues. Arrhythmia interferes with blood flow, depriving your organs of oxygen.
At Heart Care, Dr. Begum sees many types of arrhythmia, including:
Some arrhythmias aren’t harmful, but others could be life-threatening.
An arrhythmia results from disruption to the electrical signals originating in the heart’s sinus node, which regulates your heartbeat. It may be caused by an abnormality that developed before birth (congenital heart defect) or a condition, such as:
Your risk of arrhythmia increases if you smoke, drink heavily, experience chronic stress, or take certain medications.
In addition to the slow, fast, or irregular heartbeat, arrhythmia symptoms also include:
Some arrhythmias cause syncope (fainting).
Following a physical exam, medical history check, and symptom review, Dr. Begum might recommend tests to learn more about your arrhythmia.
An electrocardiogram (EKG) records the heart’s electrical activity, and an echocardiogram provides moving images of the heart to see how well it functions. Some people need to wear a Holter or event monitor — a portable device that records their heart’s activity over several days or weeks.
In some cases, more advanced tests, like tilt-table testing or electrophysiology studies, might be necessary. Or Dr. Begum, or another provider may recommend a cardiac workup after you have a stroke.
Lifestyle modifications often help manage arrhythmia, so Dr. Begum might advise you to stop smoking, lose weight, exercise more, and change your diet. You may need to take antiarrhythmics or other medications. Dr. Begum and the team can asses your need for blood thinners if it’s determined that you have heart disease.
Some people benefit from cardiac ablation, which destroys abnormal heart cells. Dr. Begum can also assess you for a pacemaker or a defibrillator implant that detects arrhythmia and corrects it with electrical impulses.
