The Arrhythmia Programme at CVSKL is a one stop centre for screening, diagnosis, surveillance and treatment for all irregular heartbeat diseases.

心房颤动(AF)

What is Atrial Fibrillation (AF)?

Your heart is divided into 4 chambers. The 2 upper chambers are called the left and right atrium, and the lower 2 chambers are called the left and right ventricles. With each beat of your heart, blood is pumped to and from other parts of the body. The pumping is controlled by your hearts’ electrical system. When resting, a normal adult heart usually beats 60-120 times per minute.

Atrial fibrillation (AF) is an irregular heart rhythm condition that affects upper chambers (atria) of the heart. This arrhythmia prevents blood from being pumped efficiently to the rest of your body. AF itself is not life threatening but it can lead to stroke and heart failure so it has potentially serious side effects.

When AF occurs, disorganized electrical signals cause the atria to quiver rapidly and irregularly, instead of beating in a regular rhythm. Because the heart chambers are not working together properly, this can reduce the heart’s ability to pump blood efficiently to the rest of the body.

What are the symptoms of AFib?

Symptoms may vary depending on the severity of your case, its causes and your overall health. You may notice:

What are the risk factor of AFib?

此外,以下的危险因素也会增加AF的风险

What are the causes of AFib?

The causes of AF are often unclear. AF may be caused by:

• Heart abnormality from birth

•Damage to the heart structure from a heart attack

•Heart valve problems

People with otherwise normal healthy hearts may also develop AF.

FAQ About Atrial Fibrillation (AF)

Q: What is the greatest risk of having AF?

A: Stroke. You are 5 times more likely to develop a stroke than someone who doesn’t have AF. Blood may not be properly pumped out of the heart which may cause it to pool and form a clot. This clot can then travel to the brain and block the flow of blood to part of the brain which can result in stroke.

Q: I don’t feel any symptoms/My symptoms come and go. Can I leave it alone?

A: AF can be a serious medical condition that should be treated no matter what level of symptoms you experience. Without effective treatment, AF may lead to stroke, heart failure and other health complications.

Q: Can I live a long life with AF?

A: People can live long and healthy lives with AF. Controlling your risk factors for heart disease and stroke and knowing what could possibly trigger your AF will help improve your long-term management of AF. Your electrophysiologist can help you manage it for life.

Diagnostic Services

Along with the standard methods of diagnosis, our team has special expertise in diagnostic procedures that measure the electrical conduction of the heart, abnormal heartbeat episodes (arrhythmia) and changes to the heart and blood pressure. The team also looks at electrical images of a patient’s heart to determine how well the heart is working. Testing includes:

  • Cardiac rhythm monitoring

  • Electrocardiograms (EKGs)

  • Electrophysiology studies

  • Tilt table studies

Medication

Medication

Medication such as calcium channel blockers and beta blockers can be used to help slow conduction of electrical impulses to maintain a slower heart rate:

  • Rate control: helps lower heart rate and regulate the pace of electrical currents.

  • Rhythm control: helps to keep heartbeat and rhythm patterns normal.

  • Anticoagulants (“blood thinners”): to reduce the risk of blood clot formation that can lead to stroke or to treat an existing blood clot.

心脏复率

Cardioversion is a medical procedure that restores a normal heart rhythm in people with certain types of abnormal heartbeats (arrhythmias). It is usually done by sending electric shocks to your heart through electrodes placed on your chest. It’s also possible to do cardioversion with medications.

Left Atrium Appendage

When blood is not pumped properly out of the heart, it may pool in the left atrial appendage and form a clot. If you are at risk for stroke and need to take oral anticoagulants but are either unable or unwilling (because of the associated high risks), LAAC is an implant designed to keep harmful blood clots from entering the blood stream by occluding the LAA. Be sure that you thoroughly understand the risks and benefits associated.

Ablation (这是一个微创程序,以阻止异常电信号的传递来治疗心律不整。)

Ablation is a procedure using. either heat (radiofrequency ablation) or freezing (cryoablation) on the area of your heart that’s causing the abnormal heart rhythm (or arrhythmia). This treatment creates scar tissue which breaks abnormal circuits in the heart and destroys areas of the heart muscle which are triggering arrhythmia.

Which Rhythm Problems Can Be Treated with Ablation?

Catheter ablation can be used to treat many arrhythmias that caused fast heartbeats.

Catheter ablation may be recommended for:

  • Paroxysmal supraventricular tachycardia, which includes:

  • Wolff-Parkinson-White syndrome

  • AV nodal re-entrant tachycardia

  • Atrial tachycardia

  • Atrial flutter

  • Atrial fibrillation

  • Inappropriate sinus tachycardia

  • Ventricular tachycardia
