Vibrating arrhythmia of
The one who at least once tested an attack of vibrating arrhythmia will never forget it because a state this extremely unpleasant, becoming complicated besides fear of instant death. The person who had attacks of vibrating arrhythmia has to pass comprehensive inspection, know well, than he suffers and what first aid is necessary for it in case of an attack.
the Carrying-out system of heart
Heart of the person possesses ability to be reduced under the influence of impulses which arise in him (avtomatiya). Avtomatiya is provided with special muscles which form a number of knots and bunches in heart - the carrying-out system into which enter:
- the sinoatrialny knot - in the right auricle, is the leader in emergence of nervous impulses, branches to atrioventricular knot depart from it; atrioventricular (predserdno - ventricular) the knot - is located
- in a mezhpredserdny partition on the right, from it on branches impulses are carried out to ventricles; can generate nervous impulses when the sinoatrialny knot does not work.
In heart also the additional paths connecting auricles and ventricles bypassing atrioventricular knot which matter when carrying out impulses in ventricles in case of defeat of atrioventricular knot are.
What is vibrating arrhythmia?
Vibrating arrhythmia is a violation of a rhythm of heart at which from - for violations of conductivity there is a chaotic reduction of muscle fibers of auricles, but auricles in general are not reduced, duration of warm cycles considerably fluctuates and has casual character, excitement is not transferred in due time to ventricles, ventricles are reduced spasmodically, with a frequency of 250 - 300 ud. 1 minute, coordination between reductions of auricles and ventricles is broken.
Vibrating arrhythmia can have more or less constant character or be shown in the form of attacks.
of the Reason of developing of vibrating arrhythmia and its prevalence
Vibrating arrhythmia can arise at such severe damages of heart as malformations of the mitralny valve (the valve between the left auricle and a ventricle), coronary heart disease, the increased function of a thyroid gland (thyrotoxicosis), chronic alcoholism etc. Attacks of vibrating arrhythmia can arise against a myocardial infarction, at sharp poisoning with some medicines (warm glycosides, caffeine) or alcohol. Sometimes the attack arises against tension and a chronic stress.
the Frequency of prevalence of vibrating arrhythmia makes less than 1% at people more young than 60 years and more than 6% at patients are more senior than 60 years.
As the attack of vibrating arrhythmia proceeds?
Attacks of vibrating arrhythmia can proceed differently, everything depends on a condition of heart. Patients can not notice at all that they changed a warm rhythm or to feel uncertain unpleasant feelings in heart. But the attack is more often it is felt in the form of sudden chaotic heartbeat. If the frequency of reduction of ventricles is very big, then there is the general weakness, dizziness, a subconscious state, and sometimes and a faint.
of Complication of vibrating arrhythmia
Vibrating arrhythmia can cause sharp heart failure - heart does not cope with the work, hypostasis of lungs can be result of what. The disease can be also complicated by a thrombembolia (blood clot corks a blood vessel).
Not less frequent complication at vibrating arrhythmia is the ischemic stroke - result of insufficient supply with brain takna blood.What inspections are necessary for
at vibrating arrhythmia?
to establish the correct diagnosis, it is necessary to reveal vibrating arrhythmia, conditions of its emergence and the termination, and also to reveal a disease which brought to it.needs to make by
For detection of vibrating arrhythmia the electrocardiogram (electrocardiogram), but on a usual electrocardiogram vibrating arrhythmia comes to light not always (the attack can pass). Therefore electrocardiograms register within a day (it is called holterovsky monitoring).
Often arrhythmias arise at physical activities therefore for measurement of level of admissible physical activity and an assessment of preventive action of antiarrhytmic drugs sometimes do an electrocardiogram with physical activity and against drug intake.by
For exact diagnosis of arrhythmias conducts electrophysiological research of heart with introduction to a catheter heart cavity.
Treatment of vibrating arrhythmia
Treatment of vibrating arrhythmia includes treatment of the main disease (for example, a myocardial infarction) and restoration of a normal rhythm of heart.
As a rule, treatment of arrhythmia begins with purpose of antiarrhytmic preparations which only the doctor as all of them have the indications and contraindications has to appoint, the patient will not be able to understand it.by
In certain cases for elimination of vibrating arrhythmia performs operation of a radio-frequency ablation when the normal rhythm of heart is restored by cauterization of very small, carefully verified heart site by means of a special catheter.
Other type of operation is a restoration of a normal rhythm of heart by means of the artificial driver of a rhythm (pacemaker). The pacemaker is usually implanted into the left subclavial area, electrodes from it are carried out through a puncture in a subclavial vein to heart.
