Atrial Fibrillation

Interventional Cardiologist Dr. Lim offers Atrial Fibrillation in her cardiology clinic at  Singapore which is a heart condition with heartbeat irregularities or abnormalities. For a normal heart rate, the beats per minute is between 60 and 100 when resting. If it gets higher than 100 or lower than 60, sometimes you would feel dizzy or maybe even experience shortness of breath, tiredness and chest pain. There are also some instances where a person doesn’t feel any of the symptoms and is totally unaware of their irregular heart rate.

With atrial fibrillation, your atria (heart’s upper chamber) randomly contracts and sometimes your heart muscle cannot relax properly due to rapid contractions, which leads to the reduced performance and efficiency of your heart. It happens when the abnormal electrical impulses jump-start the atria causing the impulses to override the natural pacemaker to the point that it cannot control the rhythm of your heart anymore.

Screening Atrial Fibrillation

In order to confirm the diagnosis of atrial fibrillation, one of the tests you need to undergo is the electrocardiogram (ECG). This test will record the rhythm and electrical activity of your heart by attaching electrodes to your arms, legs, and chest where the wirings are connected to the ECG machine. Every time that your heart beats it sends tiny electrical signals to the machine and the graph results appear on paper.

When do I need to see a heart specialist?

First, check your pulse. If your beats per minute is less than 60 or more than 100, then you need to seek a cardiologist. Additionally, if you’re experiencing chest pain and sudden changes in your heartbeat, don’t think twice and consult our interventional cardiologist right away.

How do I check my pulse?

To check your pulse:

  1. Sit down for 5 minutes
  2. Hold your left hand out. Make sure that your palm is facing upward and your elbow is slightly bent.
  3. Place your index finger and middle finger of your right hand on your left wrist towards the base of the thumb.
  4. Using your chronometer, count the number of beats for 30 seconds and multiply it by 2 to get your heartbeat per minute.

Treatments Atrial Fibrillation

If people with atrial fibrillation are left untreated, it increases the risk of having a stroke or, worst case scenario, may lead to heart failure. Treatments such as medicine to control the heart rate are given. Sometimes, a procedure called cardioversion is done to restore normal heart rhythm by controlling the electric shock going to the heart. A catheter ablation is also an option. It is a procedure that destroys the damaged area of the heart and interrupts the abnormal electrical circuit by using high-frequency radio waves that produce heat. Atrial Fibrillation may also be treated with a Watchman Device to reduce risk of stroke.
