Heart Block- Warning Signs You Must Not Ignore

Heart block is one of the most common issues in India, this may refer to the changing lifestyle of the people, the type of diet they are taking, and other medical conditions. Now, what is the reason for heart block? It is mainly caused when the electrical signals from the heart are delayed or blocked. Read this blog and learn everything about a heart block, common signs to look out for, major causes, and when to see a doctor. 

What is Heart Block?

Heart block, also known as atrioventricular (AV) block, is a condition where the electrical signals that tell your heart to beat don’t flow properly. This can cause your heart to beat too slowly or irregularly.

There are three types of heart blocks:

  1. First-degree: The signals are slow, but still reach the heart.
  2. Second-degree: Some signals don’t reach the heart.
  3. Third-degree (complete): No signals get through, which can be life-threatening.

Common Warning Signs of Heart Block

Heart block can often go unnoticed in its early stages. But here are some warning signs that should not be ignored:

  1. Dizziness or Light-headedness: The first important sign to watch out for is dizziness or light-headedness at times. It means when you feel like you are losing balance or about to faint. You can consider this as a sign your heart isn’t pumping enough blood to your brain.
  2. Slow or Irregular Heartbeat: A pulse that feels too slow or skips beats regularly may be a symptom of heart block. Don’t ignore it, even if it comes and goes.
  3. Fatigue Without Reason: Do you feel tired even after sleeping well? Unexplained fatigue could mean your heart is struggling to keep up.
  4. Shortness of Breath: If you feel breathless while doing light activities like walking or climbing stairs, it may be due to poor heart function caused by a block.
  5. Chest Pain or Discomfort: Though not always present, chest pain or a feeling of pressure in your chest can signal something serious, especially in complete heart block.

What Causes Heart Block?

Heart block can be caused by:

  • Ageing (common in older adults)
  • Heart diseases or damage from a heart attack
  • High blood pressure
  • Congenital heart defects (present from birth)
  • Certain medications (used for BP, anxiety, etc.)
  • Infections such as Lyme disease or rheumatic fever

When Should You See a Doctor?

You should seek immediate medical attention if:

  • You experience fainting spells
  • Your heartbeat feels very slow or irregular
  • You have chest pain along with shortness of breath
  • You’ve had a recent heart issue and feel extra tired or dizzy

Early diagnosis can help prevent serious complications like heart failure or cardiac arrest.


FAQs

  1. Is heart block permanent?
    Not always. Some mild heart blocks are temporary and may improve once the cause is treated (like changing medications or treating an infection). Others, especially third-degree blocks, may be permanent and need a pacemaker.
  1. Can heart block be cured without surgery?
    Mild cases can often be managed with medication or lifestyle changes. But complete heart block usually requires a pacemaker, which is a minor surgical procedure.
  2. Is heart block the same as a heart attack?
    No. A heart attack is caused by blocked blood flow to the heart muscle, while heart block is an electrical signal problem. However, a heart attack can sometimes lead to a heart block.
  3. What are the risk factors for heart block in India?
    High blood pressure, diabetes, heart disease, smoking, and aging are major risk factors, especially in India where lifestyle-related diseases are common.
