of Violation of heartbeat usually very much disturb the person, cause in it feeling of alarm, desire to take immediate measures for elimination of these phenomena. Whether always such states are really life-threatening or sometimes on them you should not turn attention?
Bradycardia and the carrying-out system of heart
Bradycardia is a reduction of heart rate less than to 60 blows 1 minute.
the Main feature of heart is ability to be reduced under the influence of impulses which arise in him. Even the heart which is completely isolated from the nervous terminations continues to be reduced. This phenomenon is called an avtomatiya. Avtomatiya is provided with special muscles which form a number of knots and bunches in heart - the carrying-out system. Enter it sinusno - predserdny knot, predserdno - ventricular knot and branches (bunches) from them on which to a cardiac muscle nervous impulses are carried out.
Bradycardia can be two types - sinusovy and owing to blockade of carrying out impulses between sinusno - predserdny knot and an auricle or between an auricle and ventricles.bradycardia
of Sinusovaya bradycardia can be observed by
of Sinusovaya at quite healthy people or from - for congenital automatism decreases sinusno - predserdny knot, or at athletes is as a result of the change of the power mode of an organism and the mode of blood circulation connected with continuous trainings.
Pathological (connected with violations) sinusovy bradycardia often happens a consequence of irritation of the wandering nerve at its sdavleniye, influences on sinusno - predserdny knot of some chemical and medicinal substances (for example, quinine), some diseases of heart (for example, myocarditis).
characterizes sinusovy bradycardia by rare pulse (60 - 40 beats per minute). Usually it does not cause violation of blood circulation and seldom is followed by any unpleasant feelings.
Bradycardia at blockade of heart
Bradycardia at violation of conductivity between sinusno - predserdny knot and an auricle (sinoaurikulyarny blockade) is caused by the fact that not each impulse extends to a myocardium of an auricle and ventricles therefore the number of warm reductions are less. Such bradycardia can pass at physical activity and at reception of some drugs (for example, caffeine).
the Bradycardia caused by violations of conductivity between an auricle and ventricles is characterized rare (sometimes less than 40 beats per minute) by reductions of heart. At this form of blockade of an auricle and ventricles are reduced in a different rhythm.Moderate bradycardia usually does not lead
to blood circulation violations. Complaints to weakness, semi-unconscious and unconscious states are possible at bradycardia less than 40 beats per minute, and also at bradycardia against severe damages of a myocardium.
One of manifestations of sharp delay of rate of warm reductions the syndrome of Morganyi - Adams - Stokes who is characterized by sudden developing of attacks with loss of consciousness and temporary cardiac arrest can be p>
Sindrom Morganyi - Adams - Stokes. There is this syndrome at violations of conductivity between auricles and ventricles.
the patient has a dizziness, dark circles before eyes, he turns pale and in several seconds faints, then spasms begin, quite often there is an involuntary urination, the termination of breath and cardiac arrest. With restoration of action of the heart of the patient quickly recovers consciousness, but usually does not remember what happened to it.Treatment of bradycardia
Treatment of bradycardia is expedient
only in the presence of the related violations of blood circulation (attacks of weakness, dizziness etc.). Treatment of the main disease which led to emergence of bradycardia (myocardites, coronary heart disease etc.) is surely carried out. by
Depending on why bradycardia began, appoint the medicines promoting acceleration of a warm rhythm (a belladonna, caffeine etc.) .
First aid at a syndrome of Morganyi - Adams - Stokes
At a syndrome of Morganyi - Adams - Stokes needs to call urgently the ambulance and before her arrival to give help as at cardiac arrest.It is necessary for
:to provide to
- passability of airways: to lay the patient on a back, him to throw the head back (to bring one hand under a neck, to press the second a forehead - the head is thrown back) and one or two hands to hold the lower jaw, pushing it forward; it is necessary to prevent a language zapadeniye;
- to carry out an artificial respiration by the “mouth in a mouth“ method: one hand to hold a nose, and to enclose another under the patient`s neck, then to make a deep breath, to densely press the lips to lips of the patient and to blow air, the exhalation of the patient makes; to repeat 2 - 3 inflations and to probe pulse; if pulse appeared, to continue to breathe before restoration of independent breath or arrival of ambulance if is not present, to begin massage of heart;
- to restore circulation of blood circulation by indirect massage of heart, squeezing heart between a breast and a backbone: to impose a palm on the lower third of a breast, from above - the second palm, to pressure her straight arms, using all weight of a body; to make 12 fast pressure upon a breast, then - 2 breaths and so on; under shoulders of the patient it is necessary to enclose the roller (for example, from clothes) that the head kept the unbent situation.
Bradycardia is not an independent disease but only a sign of this or that it is warm - a vascular disease therefore it proceeds differently.
