What is heart block? What are its possible consequences?

Sometimes in the conclusion to electrocardiogram the patient can see the diagnosis of “heart block”. What can it mean? How dangerous is this condition? Of course, it is better to consult to the cardiologist, but if not, you need to know the main information about the types and causes of heart block.

What causes heart block?

Heart block is a disturbance of the electrical impulse on a particular section of the cardiac conduction system. The contraction of the heart, which ensure its continuous operation, occur under the influence of electric pulses, which are generated and posted for all phases of cardiac muscle conducting system of the heart. The normal impulse arises in the sinus node, located in the upper part of the right atrium. Then this impulse spreads to the Atria, causing their contraction, extend to the ventricles. When impulse conduction somewhere is broken, then it is about the heart block.

Causes blockade of the cardiac muscle. Almost any lesion can provoke this side effect. So, the blockade heart can cause myocarditis, stenocardia, myocardial infarction, other cardiac diseases, physical stress (important for professional athletes). In addition, before the blockades can result in overdose or misuse of certain medicines. It happens that the blockade occurs due to disorders in the prenatal development of the child.

What are the types of heart block?

Heart block distinguish for a site on which there are problems with the conduction of impulses, but also according to its severity, that is its strength. According to the latest criteria heart block is:

  • The blockade And the degree, when the impulses are conducted, but with a delay.
  • Blockade of II degree, or incomplete – part of the impulse is not conducted at all.
  • Blockade III degree, full – impulses are not conducted at all. Its consequence can be loss of consciousness, convulsions and even death.

A closure is the bar, which exists all the time, and transitory, that occurs sometimes and is not constant.

How to deal with heart block?

Many heart blockages are dangerous, so if you notice heart rhythm disorders (rapid or slow pulse, irregular pulse), immediately consult to a cardiologist.

Heart block may occur intermittently, therefore, to identify these sometimes do not fit conventional electrocardiography. This files most often for diagnostic blockade using Holter monitoring when using special equipment that a person wears on a day, and sometimes longer, measured indicators of cardiac activity after a certain period of time. For diagnosis may also require echocardiography (ultrasound of the heart).

Some of the blockade do not require special treatment, however, can be a symptom of certain heart disease. Other blockade are treated with medication. The most dangerous are complete heart block, they are the indication for implantation of the artificial pacemaker. Can also be used for electrostimulation of the ventricles of the heart.

Strategy for the treatment of heart block depends on the location of its occurrence, and its severity. Therefore, to treat this condition impossible. You should consult a physician for all diagnostic and therapeutic procedures and to obtain recommendations regarding conservative treatment of heart block.
