Recently i had an ECG just for practice and when i looked at my result, someone pointed out that i had an odd wave shape for my heartbeat.
Turns out i have a RBBB
A right bundle branch block (RBBB) is a heart block in the electrical conduction system. During a right bundle branch block, the right ventricle is not directly activated by impulses travelling through the right bundle branch. The left ventricle however, is still normally activated by the left bundle branch.
Normally, electrical impulses within your heart’s muscle signal it to beat (contract). These impulses travel along a pathway, including the right and the left bundles. If one or both of these branch bundles become damaged — due to a heart attack, for example — this change can block the electrical impulses and cause your heart to beat abnormally.
The underlying cause for bundle branch blocks may differ depending on whether the left or right bundle branch is affected. It’s also possible that this condition can occur without any known underlying cause. Specific causes may include:
- A heart abnormality that’s present at birth (congenital) — such as atrial septal defect, a hole in the wall separating the upper chambers of the heart
- A heart attack (myocardial infarction)
- A viral or bacterial infection of the heart muscle (myocarditis)
- High blood pressure (hypertension)
- A blood clot in the lungs (pulmonary embolism)
The main complication of bundle branch block is a slow heart rate, which can sometimes cause fainting.
People who have a heart attack and develop a bundle branch block have a higher chance of complications, including sudden cardiac death, than do people who have heart attacks and don’t develop a bundle branch block.
Because bundle branch block affects the electrical activity of your heart, it can sometimes complicate the accurate diagnosis of other heart conditions, especially heart attacks, and lead to delays in proper management of those problems.
Luckily most people with bundle branch block are symptom-free and don’t need treatment. Im positive that this is a benign factor, and healthy diet and exercise should really minimise any risks that would be likely from this defect.
Science aside, how does that make me feel?
A little stressed and worried, but since its not life threatening, im more or less alarmed at i never knew about it until today. At 24 years old. Its an odd thing to hear.
