Heart rhythm disorders, also known as arrhythmias, can range from harmless to life-threatening, significantly impacting one’s heart function and overall quality of life. For individuals experiencing symptoms like palpitations, dizziness, or even fainting, seeking the expertise of an arrhythmia specialist Singapore can provide accurate diagnosis, effective treatments, and long-term management plans.

In this article, we will explore what arrhythmias are, their symptoms, causes, and the treatment options available. We will also highlight the role of an arrhythmia specialist in Singapore, how they diagnose and treat heart rhythm disorders, and how patients can benefit from the advanced cardiac care provided in Singapore.

What is Arrhythmia?

Arrhythmia refers to any irregularity in the heart’s rhythm. This can mean the heart beats:

• Too fast (tachycardia),
• Too slow (bradycardia), or
• Irregularly (fibrillation or flutter).

The heart’s rhythm is controlled by electrical signals. When these signals are disrupted, the heart may lose its regular rhythm, causing symptoms that range from mild to severe.

Types of Arrhythmias

1. Atrial Fibrillation (AFib)
   • The most common type of arrhythmia. The upper chambers (atria) beat chaotically, leading to an irregular and often rapid heart rhythm.
   • AFib significantly increases the risk of stroke and heart failure.
2. Supraventricular Tachycardia (SVT)
   • Abnormally fast heart rhythms originating in the upper chambers of the heart.
3. Ventricular Tachycardia (VT)
   • A life-threatening arrhythmia that originates in the lower chambers (ventricles) and can cause sudden cardiac arrest.
4. Bradycardia
   • A slow heart rate, often caused by issues with the heart’s electrical system.
5. Premature Ventricular Contractions (PVCs)
   • Extra, abnormal heartbeats that begin in the ventricles and disrupt normal rhythm.
6. Ventricular Fibrillation (VFib)
   • A severe, chaotic heart rhythm that requires immediate medical attention to prevent sudden cardiac death.

What Are the Symptoms of Arrhythmia?

Arrhythmias may not always cause noticeable symptoms, but when they do, they can significantly impact your daily life. Common symptoms include:

• Heart Palpitations: Feeling as if the heart is racing, skipping beats, or fluttering.
• Dizziness or Lightheadedness: Reduced blood flow to the brain can cause these sensations.
• Shortness of Breath: Difficulty breathing, especially during physical activity.
• Chest Pain or Discomfort: May occur during episodes of arrhythmia.
• Fatigue: A constant feeling of tiredness due to reduced heart efficiency.
• Fainting (Syncope): Severe arrhythmias may cause a temporary loss of consciousness.

If you experience any of these symptoms, consulting an arrhythmia specialist Singapore promptly is critical to determine the cause and severity of your condition.

What Causes Arrhythmias?

Arrhythmias are caused by disruptions in the heart’s electrical system. Several underlying factors can trigger or contribute to arrhythmias, including:

1. Heart Conditions
   • Coronary artery disease, heart attacks, or heart failure.
   • Structural heart abnormalities or valve disorders.
2. High Blood Pressure (Hypertension)
   • Chronic high blood pressure can strain the heart and disrupt its rhythm.
3. Electrolyte Imbalances
   • Abnormal levels of potassium, sodium, calcium, or magnesium can affect heart function.
4. Thyroid Disorders
   • An overactive or underactive thyroid gland can lead to heart rhythm abnormalities.
5. Medications
   • Certain medications, such as decongestants, stimulants, or antiarrhythmics, can trigger arrhythmias.
6. Lifestyle Factors
   • Excessive alcohol consumption, smoking, caffeine intake, and stress can precipitate arrhythmias.
7. Genetics
   • Some arrhythmias are inherited, such as Long QT Syndrome or Brugada Syndrome.
8. Sleep Apnea
   • Untreated sleep apnea can cause arrhythmias like atrial fibrillation.

By identifying and addressing the underlying cause, an arrhythmia specialist Singapore can recommend the most effective treatment plan for patients.

How is Arrhythmia Diagnosed?

The first step to treating arrhythmias is a proper diagnosis. Arrhythmia specialists in Singapore use advanced technology and techniques to pinpoint the cause and type of arrhythmia.

1. Detailed Medical History and Physical Examination

Your doctor will ask about your symptoms, medical history, family history, and lifestyle factors to identify potential triggers.

2. Electrocardiogram (ECG/EKG)

An ECG records the electrical activity of the heart and is often the first test used to diagnose arrhythmias.

3. Holter Monitor

A portable ECG device worn for 24-48 hours to monitor heart rhythm during normal activities.

4. Event Monitor

For intermittent arrhythmias, an event monitor is worn for weeks to record abnormal rhythms when symptoms occur.

5. Echocardiogram

This ultrasound test evaluates the heart’s structure, function, and blood flow.

6. Stress Test

Monitors heart rhythm during physical activity to detect arrhythmias triggered by exertion.

7. Electrophysiology Study (EPS)

An invasive test where catheters are placed in the heart to study its electrical pathways and identify arrhythmia origins.

8. Cardiac MRI or CT Scan

Advanced imaging provides detailed views of the heart’s anatomy to detect structural abnormalities.

A combination of these tests enables an arrhythmia specialist Singapore to accurately diagnose the condition and develop a personalized treatment plan.

Treatment Options for Arrhythmias in Singapore

Once diagnosed, arrhythmias can often be managed or treated effectively. Treatment plans depend on the type, severity, and underlying cause of the arrhythmia.

1. Lifestyle Modifications

For mild arrhythmias, lifestyle changes can help prevent or manage symptoms:

• Avoid caffeine, alcohol, and smoking.
• Reduce stress through relaxation techniques like yoga or meditation.
• Maintain a heart-healthy diet to control blood pressure and cholesterol.
• Manage sleep apnea if present.

2. Medications

Medications can help control arrhythmias and reduce complications:

• Antiarrhythmic Drugs: Medications like Amiodarone or Flecainide help regulate heart rhythms.
• Beta-Blockers: Reduce heart rate and control arrhythmias.
• Calcium Channel Blockers: Relax blood vessels and lower heart rate.
• Anticoagulants (Blood Thinners): For atrial fibrillation patients to prevent blood clots and reduce stroke risk.

3. Medical Procedures and Interventions

a. Catheter Ablation

• A minimally invasive procedure where an arrhythmia specialist uses radiofrequency energy or cryotherapy to destroy abnormal heart tissue causing irregular rhythms.
• Benefit: Highly effective for atrial fibrillation, SVT, and VT.

b. Pacemakers

• A small device implanted under the skin that regulates slow heart rhythms by sending electrical impulses to the heart.

c. Implantable Cardioverter Defibrillators (ICDs)

• For patients at high risk of sudden cardiac arrest. ICDs detect life-threatening arrhythmias and deliver electrical shocks to restore normal rhythm.

d. Cardioversion

• Uses electrical shocks or medications to restore normal heart rhythm, particularly for atrial fibrillation.

e. Maze Procedure

• A surgical procedure that creates scar tissue to block abnormal electrical signals in the heart.

f. Left Atrial Appendage Occlusion (LAAO)

• A device-based procedure for AFib patients who cannot take anticoagulants.

4. Follow-Up and Monitoring

Arrhythmia specialists in Singapore emphasize regular follow-ups to monitor heart health, adjust treatments, and prevent complications. Patients are often provided with wearable devices or remote monitoring tools to track heart rhythms.
