Arrhythmia Can Be Treated: A Patient's Successful Atrial Fibrillation Journey in Thailand

How Early Diagnosis and Advanced Cardiac Care Helped One International Patient Regain Peace of Mind

An irregular heartbeat can be alarming, especially when symptoms interfere with daily life or occur without warning. While some heart rhythm disorders are harmless, others require prompt medical evaluation because they may increase the risk of serious complications if left untreated.

One patient at Samitivej Hospital shared his experience of being diagnosed and treated for atrial fibrillation (AFib)—the most common type of arrhythmia. Through comprehensive cardiac evaluation and personalised treatment, he was able to manage his condition and improve his quality of life.

Although every patient's condition is different, his story demonstrates how early diagnosis, expert cardiology care, and appropriate treatment can make a significant difference for people living with heart rhythm disorders.

What Is Arrhythmia?

Arrhythmia is a general term for conditions that affect the heart's normal rhythm.

Instead of beating at a steady pace, the heart may:

Beat too fast (tachycardia)
Beat too slowly (bradycardia)
Beat irregularly
Skip beats
Feel like it is fluttering or racing

Some arrhythmias cause few or no symptoms, while others require urgent medical attention.

Understanding Atrial Fibrillation (AFib)

Atrial fibrillation (AFib) is the most common sustained heart rhythm disorder.

It occurs when the upper chambers of the heart (the atria) beat in a rapid and uncoordinated manner, causing an irregular heartbeat.

Without appropriate medical evaluation and treatment, AFib may increase the risk of complications such as stroke or heart failure in some patients. The level of risk varies depending on individual health factors, making timely assessment by a cardiologist essential.

Common Symptoms of Atrial Fibrillation

Symptoms vary from person to person.

Some people experience:

Heart palpitations
Rapid heartbeat
Chest discomfort
Shortness of breath
Fatigue
Dizziness
Reduced exercise tolerance
Light-headedness

Others may have no noticeable symptoms and are diagnosed during a routine health examination.

Why Early Diagnosis Is Important

Prompt diagnosis allows healthcare professionals to determine:

The type of arrhythmia
Possible underlying causes
Individual stroke risk
The most appropriate treatment strategy

Early evaluation can also help reduce the risk of complications associated with certain arrhythmias.

Anyone experiencing persistent palpitations, unexplained dizziness, fainting, or chest pain should seek medical attention promptly.

How Arrhythmia Is Diagnosed

Cardiologists may use several tests to evaluate heart rhythm disorders, including:

Electrocardiogram (ECG)
Holter monitoring
Event recorder
Echocardiogram
Blood tests
Exercise stress testing
Cardiac CT or MRI when appropriate

These investigations help physicians understand how the heart is functioning and guide treatment decisions.

Modern Treatment Options for Atrial Fibrillation

Treatment depends on several factors, including symptoms, medical history, and the underlying cause of the arrhythmia.

Options may include:

Lifestyle Changes

Some patients benefit from managing contributing factors such as:

High blood pressure
Sleep apnea
Smoking
Excess alcohol
Obesity
Medications

Depending on the individual, medications may be prescribed to:

Control heart rate
Restore normal rhythm
Reduce stroke risk
Catheter Ablation

For selected patients, catheter ablation may be recommended.

This minimally invasive procedure uses specialised catheters to target areas of heart tissue responsible for abnormal electrical signals.

Suitability depends on the patient's condition and should be assessed by an experienced electrophysiologist.

Ongoing Monitoring

Regular follow-up helps evaluate treatment effectiveness and supports long-term heart health.

Summary
Onset of Symptoms:

The patient initially noticed mild exertion-induced shortness of breath after climbing a flight of stairs. Over the subsequent three weeks, his breathing steadily deteriorated to a severe level where lying down to sleep caused immediate breathlessness, leaving him terrified from prolonged sleep deprivation.

Medical Experience and Care:

He sought treatment at Samitivej Hospital, where he received medical care for his cardiac arrhythmia under Dr. Arapin. He expressed warm appreciation for both Dr. Arapin and the nursing team, highlighting their warm, friendly, and supportive attitude throughout his stay.

Treatment Outcome:

Following successful treatment, the patient achieved complete relief from his breathing difficulties. He can now breathe naturally without conscious effort or wheezing and has fully restored his ability to sleep comfortably.
