What is Arrhythmia?

Arrhythmia refers to an irregular heartbeat, which occurs when the electrical signals that control the heart’s rhythm do not function properly. As a result, the heart may beat too fast, too slow, or irregularly. A normal heart rhythm helps the heart pump blood efficiently throughout the body. When an arrhythmia occurs, it can affect blood circulation and may lead to symptoms ranging from mild discomfort to more serious health complications.

Common Symptoms

Some people with arrhythmia may not notice symptoms, while others may experience:
• Palpitations (feeling of a racing, fluttering, or pounding heartbeat)
• Dizziness or lightheadedness
• Shortness of breath
• Chest discomfort
• Fatigue or weakness
• Fainting or near fainting (syncope)
Symptoms may occur occasionally or persist depending on the type and severity of the arrhythmia.

Types of Arrhythmia

There are several types of arrhythmias, including:
• Tachycardia – when the heart beats too fast
• Bradycardia – when the heart beats too slowly
• Atrial fibrillation – irregular and often rapid heartbeat originating from the upper chambers of the heart
• Premature heartbeats – extra beats that disrupt the normal rhythm
Some arrhythmias are harmless, while others may require medical treatment.

Causes and Risk Factors

Arrhythmias can develop due to various factors affecting the heart’s electrical system.
Common causes include:
• Heart diseases such as Coronary Artery Disease
• Previous heart attack
• High blood pressure
• Electrolyte imbalances
• Stress or excessive caffeine intake
• Smoking
• Certain medications

How is Arrhythmia Diagnosed?

Healthcare professionals may diagnose arrhythmia through several tests, including:
• Medical history and physical examination
• Electrocardiogram (ECG)
• Holter monitoring (continuous heart rhythm monitoring)
• Stress testing
• Echocardiography
These tests help determine the type of arrhythmia and guide treatment.

When Should You Seek Medical Advice?

You should consult a healthcare professional if you experience:
• Frequent or persistent palpitations
• Dizziness or fainting
• Shortness of breath
• Chest discomfort
• Irregular or unusually rapid or slow heartbeat
Early evaluation can help identify the cause and ensure proper management.
