How bundle branch block can affect your health?

Bundle branch block


Bundle branch block is a condition in which there is a delay or blockage in the path an electrical pulse takes to make the heartbeat. Sometimes it makes it harder for your heart to pump blood through your body efficiently.

Delays or blockages can occur in the pathway that sends electrical impulses to the left or right side of the heart’s lower ventricle (ventricular).



For most people, bundle branch blocks do not cause symptoms. Some people with this condition do not know they have a bundle branch block.

In rare cases, signs and symptoms may include fainting (syncope) or feeling faint (before fainting).



If you don’t yet have heart disease, signs of heart disease, or other power outages, treatment may not be needed. However, a cardiologist will consider treatment options if:

  • heart failure heart attack
  • Fainting or dazzling spells
  • chest pain


Blocks are usually created on one side. However, if both branches are blocked, the electrical activity of the heart may be impaired. If you have any of these symptoms, tell your doctor.

  • Slow heart rate
  • Fainting part
  • Arrhythmia
  • Shortness of breath

LBBB can make it difficult for doctors to diagnose other heart diseases. These include:

Left ventricular hypertrophy (LHV). The wall of the pump chamber on the left side of the heart thickens.

Ischemia. This condition reduces blood flow to the heart.

If you are diagnosed with a left bundle branch block, be sure to consult your new doctor. This usually helps them do a better job of finding changes in your mind. For example, if you take LHV, your doctor will need to test your stress with medication rather than exercise.

It is also recommended that you carry a copy of the EKG showing that you have LBBB in an emergency such as a heart attack. That way, doctors and nurses can get to know you and give you the proper treatment.

Impulses, or electrical signals, travel through both the left and right chambers of your heart to make it pump. But if the pathway is blocked, the impulses may move slower than normal or irregularly. This is called a bundle branch block. You can read more about it on Webmd.com
