A heart block can sometimes cause you to feel dizzy, faint, a feeling of irregular or skipped heartbeats, trouble breathing, fatigue and in some cases cardiac arrest.
A heart block does not always cause symptoms.
The causes of a heart block are.
Diseases such as sarcoidosis and rheumatic fever.
Inflammatory or infectious heart conditions.
Electrolyte abnormalities.
Low thyroid levels.
Damage to your heart muscle from a heart attack or other heart muscle problems.
Damage to the heart from surgery and even getting older can cause a heart block.
A first degree heart block is not serious unless you have heart disease or have other heart problems.
Most people can lead a normal life with a heart block although you will require regular monitoring.
If the heart block does worsen it can lead to complications such as injury and fainting.
The medication that is used for heart block is Atropine or AtroPen which can enhance conduction and/or improve the rate of junctional escape. In addition, it blocks the effects of acetylcholine at the AVN, thereby decreasing the refractory time and speeding conduction through the AVN.
The branch of the nervous system that controls the heart is the sympathetic nervous system and the parasympathetic nervous system.
The function of the bundle branches is to conduct impulses to the ventricles.
The right bundle branch conducts impulses to the right ventricle and the left bundle branch conducts impulses to the left ventricle.
The bundle of His comprises of a complex organization of cells, predominantly consisting of Purkinje-type cells, slender transitional cells, broad transitional cells, and varying amounts of pacemaker cells.
The bundle of His is important as it is what transmits the impulse to the left and right bundle branches and into the ventricles, resulting in a synchronized contraction of the ventricles.
The bundle branches are also known as the Tawara branches which are offshoots of the bundle of His in your heart's ventricle.
The exact location of the bundle of His is deep within the dense connective tissue and is around 1.8 cm long in an adult heart.
The normal heart rate set by the bundle of His is 40 to 55 beats per minute.
The reason it's called a bundle of His is because it was discovered by Wilhelm His Jr. in 1893 who discovered the physical link which electrically bridges the ventricles and atria of the heart.
The organs that contains the bundle of His is the heart muscles which carry electrical signals for the regulation of the heartbeat in the body.
Another name for bundle of His is atrioventricular bundle which are the nerve fibers that stretch from your atria and ventricles.
The bundle branches divide into 2 bundle branches and the right bundle branch is what conducts impulses to the right ventricle and the left bundle branch is what conducts the impulses to your left ventricle.
The bundle of His in the heart carries the electrical signals from the AV node to the bundle branches.
The electrical system which controls your heartbeat is made of several parts which signal the hearts muscles to contract.
A right bundle branch or right bundle branch block indicates you may have underlying myocardial disease and it's also a predictor of mortality in certain people.
The cause of a bundle branch block is hypertension, high blood pressure, heart disease inflammation of the heart muscle (myocarditis).
A bundle branch block is important as it can represent underlying myocardial disease and is also a predictor of mortality in certain patient populations.
A bundle branch block can cause tachycardia and especially if it's a left bundle branch block.
Most times though a bundle branch block causes a slower heart rate instead of an increased heart rate.
A bundle branch block shows on an ECG as a widened QRS and electrocardiographic vector changes on an ECG.
A right bundle branch block can occur in those who are otherwise healthy and seem normal.
If a right bundle branch block happens with a heart attack then it can be a sign of serious heart damage.
A bundle branch block does not need treatment as long as you're experiencing no symptoms.
In some cases you may need some medication to control high blood pressure or heart failure symptoms if you're experiencing those symptoms.
Or if you're experiencing symptoms like fainting then you may need a pacemaker.
The bundle branch that is worse is the left bundle branch block as it's associated with the greatest risk of death.
Stress can cause a bundle branch block as stress increases the hearts pumping and blood flow which can lead to the bundle branch block occurring.
You cannot reverse a bundle branch block once you have it and they don't go away either but medications can help with the condition.
A bundle branch block and right bundle branch block usually does not have symptoms although there can be some symptoms with a bundle branch block and right bundle branch block which can include dizziness and fainting although in some cases you may not have any symptoms with a right bundle branch block.
A right bundle branch block can cause fatigue as well as chest pain, syncope, near syncope and dizziness.
A right bundle branch block can be temporary or permanent.
Sometimes a right bundle branch block only occurs when the heart rate exceeds a certain critical value.
And by itself a right bundle branch block does not require specific treatment.
The root cause of bundle branch block is high blood pressure and heart disease and myocarditis.
You should be concerned about a right bundle branch block if you have heart disease or suspected heart disease.
However if you don't have any heart disease then a right bundle branch block is nothing to be concerned about in most cases.
You should see a cardiologist for right bundle branch block if you already have heart disease or you want to be sure it's not becoming serious.
If you have no heart disease then a right bundle branch block is usually nothing to worry about.
You can live a long life with a right bundle branch block, especially if you don't have heart disease.
When you don't have heart disease and have a right bundle branch block the right bundle branch block does not affect or change your life expectancy and many people live normal lifespans with a right bundle branch block.
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.
