Bradyarrhythmia - a disease in which the broken heart rate and heart rate are less than 60 beats per minute.The class of this disease may include sinus bradycardia, sinus node stop, sinus block, and ciliary bradyarrhythmias trikulyarnye blockade.
Bradyarrhythmia divided into two forms: organic and functional.But regardless of the type, in this disease has always been slowing heart rate.This is due to diastolic overload.If your heart rate below 30 beats per minute, the developing brain ischemia.
Bradyarrhythmia divided into the following form:
- Sinus bradycardia, in which the heart rate less than 60 beats, but preserved sinus rhythm of the heart.This state is normal for trained people, athletes.However, for other categories of people to the development of the disease can result in an overdose of digoxin, antiarrhythmics, beta blockers, calcium channel blockers.When sinus bradycardia treatment is aimed at the abolition of the drugs that cause disease;
- nodal rhythm is different from sinus bradycardia only that which comes from the momentum of atrioventricular and not from the sinus node.However, when bradyarrhythmia persists after drug withdrawal, which caused arrhythmia, it installs a permanent pacemaker.
sinus bradyarrhythmia - a disease in which it states slowing the heart rate.It may occur in people of any age.The sinus node disease originates, as for a normal heart rhythm and to reduce it, he responds.Typically, heart disease is the system actually does not affect, and the patient usually seems quite healthy at the time of the survey.However sinus bradyarrhythmia body holds in hypoxic conditions.
Bradyarrhythmia heart occurs, usually in elderly and young people with no apparent abnormality of the heart of the system.Respiratory bradyarrhythmia in teenagers and children is very common.This is due to the fact that under the influence of the vagus nerve is a function of the sinus node, and it decreases with age.In people older than 40 years, respiratory bradyarrhythmia is evidence of the primary lesion of the sinus node or suggests dysfunction (autonomic).
Bradyarrhythmia heart may be caused by a wide variety of causes that directly affect sinus node: viral diseases, thrombosis or damage, inflammation, cardiosclerosis, myocarditis, myocardial infarction.Quite a rare disease that can occur in cancer of the heart.
Bradyarrhythmia in adolescents is common and it is possible the disease on the background of thyroid dysfunction.Overdose of drugs (digoxin, Kordaronon) also contributes to the development of the disease.Bradyarrhythmia expressed accompanied by dizziness, headache, weakness.Mild bradyarrhythmia, as a rule, are not accompanied by complaints, because it does not lead to violations of cardiodynamics.
slowing heart rate leads to reduced cardiac output, impaired blood flow to organs: infarction, cerebral (brain), skeletal muscle.
Bradyarrhythmia may develop as a result of local effects on the sinus node (inflammatory or degenerative damage).Thrombosis, or myocarditis vessels are also common causes of formation of bradyarrhythmias.Because myocardial infarction rear wall there slowing heart rate.Many disease processes can cause bradyarrhythmia, but the root cause is damage to the sinus node, as the tone of the parasympathetic nervous system.The disease always arises from the direct or indirect effects on the sinus node.
Bradyarrhythmia formed in children due to the fact that increased vagus tone, which was generated by a pathological process infarction.Hereditary predisposition, vascular dystonia, thyroid dysfunction, can also cause the development of diseases.Because of the focus of infection is affected myocardium and diseases such as angina, a viral infection contribute to the development of bradyarrhythmias.
older people the disease can manifest itself cardiosclerosis.Quite rarely the presence of cancer of the heart may occur bradyarrhythmia as damaged sinus node and compression occurs.Increased intracranial pressure, viral infections, myocardial infarction, hypothyroidism can be the cause of bradyarrhythmias.
overdose of drugs, beta blockers, cardiac glycosides, quinidine, digoxin, do not rule out the formation of bradyarrhythmias.Coronary heart disease, cardiomyopathy, blood electrolyte abnormalities can also cause the development of the disease.
moderate bradyarrhythmia may show only a single symptom: heart rate about 40 beats per minute.Severe bradyarrhythmia manifested by dizziness, loss of consciousness may be.There will also be the feeling of cardiac arrest or slow down, behind the breastbone there is a feeling of heaviness.
Conditionally distinguish compensated and decompensated cardiac bradyarrhythmia.Compensated asymptomatic form.Patients with this form of disease are able to live life, unaware of the presence of abnormalities.
clinical picture in the form of decompensated heart bradiaritmii non-specific and is based on the symptoms of cerebral circulatory disorders, however, is typical of many diseases.Syndrome Morgagni-Adams-Stokes manifest itself with an increase of bradycardia heart.In this case, the circulation may stop suddenly, urination and defecation to be spontaneous.Often, the automatism of the heart can recover spontaneously, and the patient regains consciousness.In rare cases, needed resuscitation, as can occur death.Bradyarrhythmia manifested neurological clinical picture and for that reason the treatment is carried out in patients with neurological hospitals.
sinus bradyarrhythmia manifested fatigue, fainting.With an increase in clinical blood pressure would plummet and the subsequent development of arrhythmic collapse or shock.For a patient like syndrome can be fatal.In elderly people the disease will manifest cardiosclerosis.
Also observed loss of appetite, shortness of breath, cold sweat, your blood pressure will change regularly, you will be distracted, focus will fall.
Respiratory bradyarrhythmia manifested palpitations inspiratory and expiratory rate slows.When holding the breath, this pathological manifestation disappears.In the case where this is not happening, this is evidence of a non-respiratory sinus bradyarrhythmias.
Bradyarrhythmia in children usually occurs without clinical symptoms.However, if the disease is pronounced, it is possible headaches, dizziness and weakness.If the disease is aggravated, it will be observed loss of consciousness, which are caused by a violation of blood flow to the brain.
Bradyarrhythmia children diagnosed when the heart rate less than 60 beats / min.The reason for the delayed pulse is the sinus node.With this disease, all heart system, including the work of the atria and ventricles are not compromised.Occasionally the disease appears regularly slowing heart rate.
quite often the deviation is bradyarrhythmia in children, which appears on the exhale.This condition can be caused by a cold.The disease is divided into two forms: primary and secondary, in which the heart rate slows down because of the presence of other diseases in the body (intracranial hematoma, cerebral edema, liver disease).
At an early age it is possible the development of sinus bradyarrhythmias, which is associated with increased vagal tone.In some cases, the disease manifests constant slowing of the heart rate, regardless of the impact factor or condition.Also, diagnosis can be made in the case of slow heart rate at a certain influencing factor (hypothermia).
Usually, the disease clinically manifests.In the case of complaints about the deterioration of health is necessary to conduct a comprehensive survey and monitored regularly by a cardiologist.Children's disease is not constant and often manifests itself in certain situations.
Children with thyroid problems, vascular dystonia, hereditary predisposition, infectious diseases, are most susceptible to the development of bradyarrhythmias.
not excluded in severe form of the disease pain in the heart, blurred vision, cold sweats, constant fatigue.In the event of attacks, the cardiologist may prescribe electrostimulation.Due to the violation of blood flow to the brain in a child may experience loss of consciousness.
This pathological deviation of most children is temporary and can be easily adjusted.If your child feels well and there are no complaints, the disease will retreat yourself with time.In this case treatment is not required.
Before prescribe treatment, patients need careful examination.Using ECG can detect any form of bradyarrhythmias.In patients with bradyarrhythmias passing throughout the day recorded Holter.
most effective treatment is a bradyarrhythmia pacing.In rare cases, it may be receiving the drug atropine.For patients with this disorder electrolyte solutions, vitamins and metabolic drugs are not effective.
If the disease is asymptomatic, treatment is not required.In the case of symptomatic treatment is necessary, aimed at addressing the underlying disease, which contributed to the development of bradyarrhythmias.However, do not take drugs, aimed at the acceleration of the heart rate, as these drugs can cause other forms of arrhythmia.
treatment of bradycardia with minimal threat to health is carried out by means of pacing, ie patients were mini-operation for implantation of an artificial pacemaker.
not previously conducted similar surgery and treatment was carried out with the help of drugs holinoliticheskogo, to become a heartbeat quickened.But often these drugs lead to ventricular tachycardia, which turns into ventricular fibrillation (stopped blood circulation).Drugs aimed at the acceleration of heart rate, do not reveal the true severity of the disease and do not allow timely implanted artificial pacemaker.
pacemaker is a device that generates electrical impulses.It is a system of regular monitoring of heart rhythm and other sensors that can store data and program.Regardless of the type and form of bradyarrhythmia, threatening the health of the patient, always implanted pacemaker.
Children recommended regular monitoring of ECG, since the disease is asymptomatic.In the daily diet foods should be rich in magnesium, potassium, B vitamins: dairy products, meat, nuts, dried fruits, buckwheat, oatmeal, sauerkraut, spinach, parsley, tomatoes, citrus fruits, legumes.Also recommended breathing exercises, regardless of patient age.
