What Cost of the Leader?

The warm leader - the electronic device introduced in heart of the person in basic, to make the electric impulses to make the warm contract if its system of carrying out goes the defective.
 Normal heart of the healthy person fights within 60 - 100 times every minute. This range is reflected that by a regular action of the heart safely to put oxygen to various bodies of a body especially a brain; if it goes out of or below these numbers, serious diseases can occur. The condition in what your heart fights faster, than 100 times name every minute a tachycardia. The tachycardia is caused by mechanisms to increase the oxygen reference, should reduce blood volume (probably caused, bleeding) or a respiratory problem if it goes impetuous, cardiac arrest or blow could happen. Contrast of a tachycardia - a bradycardia in which palpation goes down 60. The bradycardia reasons are very various; in limits from age deterioration of bodies to defective regulation of warm impulses. With normal autoregulating processes of a body or by means of medicines, the warm norm will come back to normal depending on the reason. However, if the reason - damage to knot kitajsko-concerning an auricle, the person, probably, require the artificial leader, he still wishes to lead a normal life.
 Knot kitajsko-concerning an auricle - the natural leader of the heart located in a roof correct atriuma. This leader regulates warm norm of the person, starting certain quantity of impulses to its next fabrics to conclude the contract. As noted above, damage or deterioration to knot SA will end to the smaller electric impulses going along a cardiac muscle, finally coming to an end to a bradycardia.
 There are two types of leaders which can be introduced for human use; leaders of unique chamber and leaders of double chamber. The leader of unique chamber only is introduced to adjacent with knot SA while the double chamber is introduced in two sites, one adjacent with knot SA and another in Atrioventrikuljarnom knot (AV) (the secondary natural leader which in general depend on knot SA) if knot AV also is damaged. Devices are introduced mainly to help natural leaders in case they do not do sufficient work, value if knot SA shoots below 60 impulses in a minute the microchip in artificial leaders will start to start own electric impulses.
 Cost of this small device is so high that doctors will never recommend it to the patients if the concrete requirement is not understood. The device costs approximately 3 000$ to 20 000$ depending on type, quality and service life of the accumulator of the leader. The patient should pay for for the hospital account which includes use of a working zone for introduction, rooms, and much more bol'shego quantities of payments. It is impossible to forget about a professional payment of your doctors. So, as a whole you should prepare 40 000$ to 100 000$, and accumulator service life would last only within approximately 10-14 years so would prepare the same sum of money for replacement of your leaders before it will die out.
