A heart block is defined by cardiologists as an interference in the electrical signals in the heart. Cardiologists in Darbhanga say that in order to understand heart block, one must understand how the heart works. These are some of the best cardiologists in India.

The heart specialists in Darbhanga explain that the heart beat starts in an area in the top chambers of the heart (atria). This area is the heart's pacemaker. The electrical signals travel to the lower chambers of the heart (ventricles). This keeps the heart beat steady and regular. A heart block occurs when the electrical signal is slowed down or does not reach the bottom chambers of the heart. The heart, as a result, may beat slowly, or it may skip beats.

Heart block may resolve on its own and is usually not a problem, but it also may be permanent and require treatment. Thus, a check-up is recommended.

Degrees of Heart Block

The severity of a heart block is measured in degrees. There are three degrees of heart block. The first degree being the mildest, and the third degree being the most severe. Here, have a look at the details:

  • First-degree heart block:
    • Rarely has symptoms
  • Second-degree heart block:
    • The electrical impulse may not reach the lower chambers of the heart.
    • The heart may miss a beat or beats and may be slow and irregular.
    • You may feel dizzy, faint, or have other symptoms.
  • Third-degree heart block:
    • The electrical signal does not move to the lower chambers of the heart. In this case, the lower chambers beat at a much slower rhythm, and the upper and lower chambers do not beat at the same rate.
    • The heart fails to pump enough blood to the body. This can lead to fainting and shortness of breath.
    • This is an emergency that needs medical help right away.


The cardiologist doctors at the super-specialty heart hospital in Darbhanga highlight the causes that are responsible for heart block as:

  • Medicine side effects. Heart block can be a side effect of digitalis, beta-blockers, calcium channel blockers, and other medicines.
  • A heart attack that damages the electrical system in the heart.
  • Heart diseases, such as heart valve disease and cardiac sarcoidosis.
  • Some infections, such as Lyme disease.
  • Heart surgery.

They also say that a person may have heart block because they were born with it. A person is more at risk for this condition if:

  • They have a heart defect.
  • Their mother has an autoimmune disease, such as lupus.
