Heart blocks are disruptions in the electrical signals that control heartbeats, leading to slow, irregular, or even absent heart rhythms. Electrophysiology is a specialized field of cardiology that studies and treats these electrical issues. In this blog, we will explore the types of heart blocks, how they are managed, and the role of cardiac electrophysiology in diagnosing and treating them. We'll also answer common questions about the process to provide a better understanding of available treatment options.

Understanding Heart Blocks: What Happens to the Heart’s Electrical System?
The heart’s electrical system controls the rate and rhythm of heartbeats. When these electrical impulses are delayed or blocked, a heart block occurs. Electrophysiology of the heart focuses on understanding these disruptions to effectively diagnose and manage heart rhythm disorders.
Types of Heart Block
Heart blocks are categorized based on severity:
1. First-Degree Heart Block
This type involves a mild delay in the electrical signal, but all impulses still reach the heart’s ventricles. It often presents with no symptoms and typically doesn’t require treatment unless associated with other heart conditions.
2. Second-Degree Heart Block
There are two subtypes:
-
Mobitz Type I (Wenckebach): Electrical signals become slower and eventually fail to reach the ventricles. Symptoms can include dizziness or lightheadedness.
-
Mobitz Type II: A more serious condition where some signals fail to reach the ventricles, leading to missed beats. It often requires a pacemaker.
3. Third-degree (Complete) Heart Block
This is the most severe form. No electrical signals pass from the atria to the ventricles, causing slow or irregular heartbeats. Immediate treatment with a pacemaker is usually required.

Symptoms of Heart Block: When to Seek Help
Common symptoms of heart blocks include:
-
Dizziness or lightheadedness
-
Fatigue
-
Fainting spells (syncope)
If you experience any of these symptoms, it is essential to seek immediate medical attention. Manipal Hospital Delhi’s cardiology team is experienced in diagnosing and managing heartblocks.
Diagnosing Heart Block: The Role of Electrophysiology Tests
Electrophysiology tests are critical for diagnosing heartblocks. These tests involve monitoring electrical signals within the heart to pinpoint the location and severity of the block.
Diagnostic Tools Used:
|
Diagnostic Tool |
Purpose |
|
Electrocardiogram (ECG) |
Records electrical activity of the heart |
|
Holter Monitor |
Captures irregular rhythms over 24-48 hours |
|
Stress Test |
Measures heart’s response to exertion |
At Manipal Hospital Delhi, our advanced diagnostic facilities and experienced electrophysiologists ensure accurate diagnosis and effective treatment.
How Electrophysiologists Manage Heart Blocks
Electrophysiology procedures vary based on the severity of the heart block:
-
Mild Heart Blocks (First-Degree)
Lifestyle modifications and regular monitoring are often sufficient.
-
Moderate Heart Blocks (Second-Degree Mobitz I)
May require medications or a pacemaker if symptoms are significant.
-
Severe Heart Blocks (Second-Degree Mobitz II and Third-Degree)
A pacemaker is the standard treatment. Pacemakers regulate the heart’s rhythm and prevent dangerous slow heartbeats.
Manipal Hospital Delhi offers comprehensive electrophysiology of the heart services, including pacemaker implantation and management.

Pacemakers: A Lifesaving Solution
Pacemakers are small devices implanted under the skin that send electrical impulses to the heart to maintain a regular rhythm. They are life-changing for patients with severe heart blocks.
Innovations in Cardiac Electrophysiology
Advancements in cardiac electrophysiology have led to innovations like leadless pacemakers, remote monitoring, and AI-based rhythm detection. Manipal Hospital Delhi stays at the forefront of these advancements to provide the best possible care.
Conclusion
Heart blocks can range from mild to life-threatening, but with the expertise of cardiac electrophysiology, effective treatments are available. At Manipal Hospital Delhi, our team of experienced electrophysiologists uses advanced diagnostic tools and treatments to provide comprehensive care for patients with heartblocks. If you or a loved one are experiencing symptoms, don’t delay seeking care.
