Heart Block is the name given to the symptoms produced by disease of the auricular-ventricular bundle or bundle of His. such disease interferes with the normal stimulus conduction from the auricles to ventricles.
A healthy human heart beats at about 60 to 100 times a minute. A heartbeat is one contraction of the heart muscles, which pushes blood around the body.
Normally, every heart muscle contraction is controlled by electrical signals that travel from the atria, or the upper chambers of the heart, to the ventricles, or the lower chambers.
A partial heart block happens when the electrical impulses are delayed or stopped, preventing the heart from beating regularly.
A complete heart block is when the electrical signals stop completely. The heartbeat will drop to about 40 times per minute.
Even changes to impulses that last only a fraction of a second can cause heart block.
Sometimes, a heart block makes it difficult for the heart to pump blood properly through the circulatory system, so the muscles and organs, including the brain, do not get enough oxygen to function properly.
There are three types of heart block.
First-degree heart block; its involves minor heartbeat disruptions, such as skipped beats. It is the least serious type of heart block, and it does not generally require treatment.
Second-degree heart block; its occurs when some electrical signals never reach the heart, causing dropped or skipped beats. The patient may feel dizzy, and they may need a pacemaker. The ventricle may not contract, as the atrial impulse did not reach the ventricles.
Third-degree or complete heart block; its happen when electrical signals do not travel between the upper and lower chambers of the heart. It is more common in patients with heart disease. Without a pacemaker, there is a serious risk of heart attack.
In a healthy heart, electrical impulses that travel inside a heart muscle instruct it to contract, or beat. The impulses move along a pathway, from the upper heart chambers, through the atrioventricular (AV) node, to the lower chambers.
Along this pathway is a cluster of cardiac fibers. These are called the bundle of His, the “bundle branch block” or the “AV bundle.” This bundle divides into two branches, the right and left bundles. The bundles conduct the electrical impulses to the heart ventricles. Each ventricle has a branch.
Damage to one of the branch bundles can cause uncoordinated ventricular contractions, and an abnormal heart beat can result.
A blocked signal on the right side of the heart is not usually serious, but a block on the left side can indicate a higher risk of coronary artery disease, or some other heart problem.
If a person has a heart block, they may experience:
The following conditions increase the risk:
People with a left side bundle branch block have a higher risk of complications than those with a right side block.
Possible complications include:
Heart block is not always avoidable, but the risk of heart disease can be reduced by consuming a healthy diet, exercising regularly, minimizing alcohol consumption, and avoiding tobacco
