Arrhythmias
What are they?
Arrhythmias are abnormal rhythms of your heartbeat (watch the video). This means that your heart may beat too slowly (bradycardia), too fast (tachycardia), or in an irregular pattern. These abnormal rhythms can occur when the electrical impulses coming from your heart don’t fire as they normally should.
There are many types of arrhythmias that can occur with varying degrees of symptoms. If you’re having symptoms that are interfering with daily living — causing fatigue, fainting or chest pain — you should be evaluated by a physician to diagnose if an arrhythmia is the cause.
Atrial fibrillation (or "afib") is the most common type of arrhythmia; it’s a fast, irregular heartbeat. In afib, electrical signals fire in a very fast or uncontrolled fashion, causing the atrial chambers of the heart to twitch, quiver or contract. Blood can pool in the heart causing blood clots, and if a blood clot travels to the brain, stroke can occur.
Symptoms
Watch a video on the signs and symptoms of arrythmias.
- Palpitations (feeling of skipped, fluttering, or heart racing)
- Dizziness, fainting or feeling lightheaded
- Shortness of breath
- Extreme fatigue or weakness; lack of energy
- Sweating
- Chest discomfort
Risk factors
- Coronary heart disease
- Hypertension
- Congenital heart disease
- Thyroid problems
- Caffeine or nicotine use
- Stress
- Sleep apnea
- Substance abuse (diet pills, illicit drugs, alcohol)
Diagnosing arrhythmia
- Complete medical history and physical examination
- Electrocardiogram (EKG)
- Electrophysiology (EP) studies
- Implantable loop recorder
- Wearable heart monitor (Holter monitor)
Treating arrhythmia
Watch the video on arrhythmia treatments.
- Medication management
- Lower your risk by not smoking, eating a healthy diet, and being active
- Radiofrequency ablation
- Defibrillator/pacemaker implant surgery
- Device implantation (i.e., Watchman™)
- Robotic cardiac ablation
Robotic cardiac ablation
The heart is a powerful muscle. It must be in order to pump a constant lifetime supply of blood to the whole body. At the same time, it is extremely delicate and intricate. Safe catheter navigation through each chamber of the heart is essential so it is important for physicians to use the best and latest technology available. HonorHealth physicians use an innovative and cutting edge robotic ablation technology to treat arrhythmias, cardiac ablation.
Cardiac ablation is a common, minimally invasive, treatment for arrhythmias. It’s used to diagnose the arrhythmia and to deliver energy that isolates misbehaving heart muscle cells, allowing for a safer and more effective cardiac ablation procedure.
What are some of the benefits?
- Short procedures and fast recovery time, enabling patients to return to normal activity within a few days
- Reduced patient exposure to X-ray radiation
- Reduced risk of complications due to perforation of heart tissue
