What is an arrhythmia?
Heart arrhythmia is an irregular beating of your heart, which can be too slow, too fast or erratic. Arrhythmia is caused by dysfunction of the electrical impulses that control your heartbeat.
Some people experience arrhythmias as a fluttering or racing heart, which can be harmless. However, serious forms of heart arrhythmias have aggravating signs and symptoms and can even be life-threatening.
There are three basic types of heart arrhythmia:
- Slow heartbeat (bradycardia) with a resting heart rate less than 60 beats per minute
- Fast heartbeat (tachycardia) with a resting heart rate greater than 100 beats per minute
- Premature heartbeat, which can feel like a skipped heartbeat but is actually an extra beat
Different types of arrhythmias involve different chambers of the heart. Your private specialist will work with you to accurately diagnose your exact type of arrhythmia and recommend the best treatment options.
Our diagnostic services
Depending on your condition and needs, experts at our arrhythmia clinic in London may use a combination of tests to accurately diagnose the precise nature of your arrhythmia, including:
- Echocardiogram
- Electrocardiogram (ECG)
- Electrophysiological testing and mapping
- Event recorder
- Holter monitor
- Implantable loop recorder
- Stress test
How do we treat arrhythmia?
Depending on your type of arrhythmia, you may or may not need treatment. Your Mayo Clinic Healthcare cardiologist will work with you and apply the most accurate testing methods available to determine your type of arrhythmia and recommend treatment options based on the results.
The nature and severity of a person's arrhythmia will dictate the types of treatment recommended, such as:
- Vagal manoeuvres involve holding your breath and straining, submerging your face in ice water, or coughing.
- Medications may control your heart rate or restore a normal heart rhythm.
- Cardioversion delivers a shock to your heart through paddles or patches on your chest to restore a normal rhythm.
- Catheter ablation damages a small spot of heart tissue and creates an electrical block along the pathway that's causing your arrhythmia.
- A pacemaker can help control abnormal heart rhythms.
- An implantable cardioverter-defibrillator detects an abnormal heart rhythm and resets it to a normal rhythm with an electrical shock.
- Maze procedure involves a series of surgical incisions in the heart to create a pattern of scar tissue, which doesn't conduct electricity, and interrupts stray electrical impulses that cause some types of arrhythmias.
- Coronary bypass surgery is reserved for people with severe coronary artery disease, in addition to arrhythmias.
Personalised treatment
Every patient’s heart rhythm condition is unique, which is why personalised care is central to everything we do. At Mayo Clinic Healthcare, your treatment plan is developed around your symptoms, medical history, lifestyle and long-term health goals. We take the time to understand how arrhythmia affects your daily life, whether that means occasional palpitations, dizziness, fatigue or more disruptive episodes.
Your cardiologist and palpitations specialist will review your diagnostic results in detail and discuss the full range of options with you. Together, you will decide on a treatment approach that balances clinical effectiveness with your preferences and priorities.
Where appropriate, your care team may consult with Mayo Clinic experts in the U.S. to ensure you benefit from global insight. This collaborative, patient-centred model ensures that you receive highly tailored treatment designed not only to manage arrhythmia, but to support your overall heart health and quality of life.
