Your heart works around the clock, pumping blood to every organ in your body without pause. When that rhythm is disrupted – beating too fast, too slow, or irregularly — it may signal a condition called cardiac arrhythmia. Found across all age groups, arrhythmia is one of the most common heart conditions and, if left untreated, can lead to heart failure or sudden death.
What is cardiac arrhythmia?
Cardiac arrhythmia (Arrhythmia) is an abnormality in the heart’s electrical system that causes it to beat too slowly, too quickly, or irregularly. This disrupts efficient blood flow throughout the body and significantly increases the risk of heart failure and stroke.
What causes cardiac arrhythmia?
- Genetics — a family history of arrhythmia increases individual risk
- Underlying health conditions — heart disease, diabetes, high blood pressure, and high cholesterol are all contributing risk factors
- Medications and substances — certain blood pressure medications, cold medicines, alcohol, and nicotine can all affect heart rhythm
- Lifestyle factors — chronic stress, physical inactivity, and a poor diet can disturb normal cardiac function
What are the warning signs?
- Heart palpitations or an unusually strong heartbeat
- Dizziness, lightheadedness, or fainting
- Unexplained fatigue or breathlessness
- Chest pain or difficulty breathing
If you or someone close to you experiences any of these symptoms, seek specialist medical attention immediately.
How is cardiac arrhythmia treated?
Treatment varies depending on the type and severity of the condition. A cardiac electrophysiology specialist will assess each patient and recommend the most appropriate approach, which may include:
- Ablation therapy — targeted destruction of the abnormal electrical circuit within the heart
- Pacemaker implantation — a device that regulates heart rhythm to maintain a steady beat
- Implantable cardioverter-defibrillator (ICD) — delivers a shock to restore normal rhythm when dangerous arrhythmia is detected

What is Pulsed Field Ablation (PFA)?
Pulsed Field Ablation (PFA) is the latest innovation in treating Atrial Fibrillation (AF) and is attracting growing interest among cardiologists in Thailand and internationally. It offers several advantages over conventional methods such as Radiofrequency (RF) ablation and Cryoablation.
Rather than using heat or cold energy, PFA delivers high-frequency pulsed electric fields in brief bursts to destroy only the abnormal heart muscle cells — leaving surrounding tissue such as the esophagus and key nerves unaffected.
Key advantages of PFA:
- High precision — targets only abnormal tissue, minimizing impact on healthy surrounding areas
- Greater safety — significantly reduces the risk of complications such as esophageal injury or phrenic nerve damage
- Shorter procedure time — faster than both RF and Cryoablation methods
- Excellent outcomes — research presented at Heart Rhythm 2025 found that 94% of pulmonary veins were successfully isolated on the first energy delivery, and over 78% of patients remained free of AF symptoms at 12 months post-treatment
