Heart conditions that require a pacemaker are bradycardia which is when your heart beats too slowly or pauses causing fainting spells.
Or if you have tachycardia which is irregular heartbeat or a heart that beats too fast can require a pacemaker.
The SA or sinoatrial node is the pacemaker of the heart and generates an electrical signal which causes your upper heart chambers called the atria to contract.
The signal then passes through the AV or atrioventricular node to your lower heart chambers called the ventricles which causes them to contract or pump.
Your SA node is considered your natural pacemaker of your heart.
A RBBB after pacemaker also known as a right bundle branch block is a condition that suggests the left ventricular is pacing due to malposition of the lead.
Right bundle branch block can result from a number of conditions, such as: Heart disease due to high blood pressure in the lungs (pulmonary hypertension) Chronic obstructive lung disease (COPD) Blood clot in the lung (pulmonary embolism)
A RBBB or right bundle branch block does not always need investigation if you're otherwise healthy although you should still have it investigated to be sure it's not a more serious condition.
If you have a left bundle branch block and not a right bundle branch block then you do need a medical exam.
RBBB or right bundle branch blocks do run in families and can be genetic or you may develop an right bundle branch block later in life.
The artery that supplies the right bundle branch is the left anterior descending artery (LAD) or atrioventricular node (AVN) artery.
The function of the right and left bundle of His is to conduct impulses and send them to the right and left ventricle.
Your left bundle branch conducts impulses to your left ventricle, and your right bundle branch conducts impulses to your right ventricle.
The bundle of His is in the right ventricle although it also has two branches.
The right bundle branch sends the electrical signals through the Purkinje fibers to the right ventricle and the left bundle branch sends the electrical signals through the Purkinje fibers to the right ventricle.
A right bundle branch can lead to a right bundle branch block that is then associated with an increased risk of death especially after you suffer a heart attack.
Also some people who have a right bundle branch block may also need a permanent pacemaker although it's rare.
The heart has 3 bundles which is the bundle of His that passes into the ventricular septum and then divides into the 2 bundle branches which are the left bundle and the right bundle.
And the AV node tapers down into the bundle of His.
The type of heart block that is a right bundle branch block is an obstacle in the right bundle branch which makes your heartbeat signal late and out of sync with your left bundle branch.
This then results in an irregular heartbeat.
The electrical signals in the heart act like a pacemaker which controls the heartbeats.
The right bundle branch block symptoms are dizziness and fainting although in some cases you may not have any symptoms with a right bundle branch block.
Right bundle branch blocks are diagnosed with an echocardiogram or EKG.
When you have a right bundle branch block it causes the right ventricle in your heart to contract a bit later than it normally should.
A right bundle branch block affects your heart's conducting system.
A right bundle branch block means the physiologic electrical conduction system of the heart, specifically in the His-Purkinje system, is altered or interrupted resulting in a widened QRS and electrocardiographic vector changes.
Right bundle branch block is an obstacle in your right bundle branch that makes your heartbeat signal late and out of sync with the left bundle.
A right bundle branch block is serious as it puts you at an increased risk of death especially after a heart attack.
Some people with a right bundle branch block may even need a permanent pacemaker in some cases.
A right bundle branch block is a condition in which there's a delay or blockage along the pathway that electrical impulses travel to make the heart beat.
If you don't have heart disease, having right bundle branch block doesn't change your life expectancy or add to your risk level.
But having right bundle branch block can put you at a higher risk of death if you also have heart failure or a heart attack.
The risks of a right bundle branch block include.
Blood clot in the lungs (pulmonary embolism)
Heart attack (myocardial infarction)
Heart structure problems that are present at birth (congenital heart defects) — such as a hole in the wall separating the upper chambers of the heart (atrial septal defect)
Many times, bundle branch blocks don't cause any symptoms, though they sometimes lead to dizziness or fainting.
Providers usually diagnose BBB with an EKG or echocardiogram.
You may not need treatment for BBB, though you'll need to treat any underlying conditions.
If you have a right bundle branch block and you're otherwise healthy, you might not need a full medical checkup.
If you have a left bundle branch block, you will need a thorough medical exam.
Tests that can be used to diagnose a bundle branch block or its causes include: Electrocardiogram (ECG or EKG).
Right bundle branch blocks typically develops progressively over time and does not go away.
However, there may be cases where Right bundle branch block is temporary and goes away when doctors treat the underlying condition.
A block in the left bundle branch is usually a sign of heart disease.
Bundle branch blocks usually do not cause symptoms.
Usually no treatment is done for bundle branch blocks directly.
