New conductor for the heart rhythm.

 A cardio stimulators century begun on 1958 y.In 6 years later ,and 60 years from weighty metallic box with a minimal kit functions  a cardio stimulator turned in miniature computer, creating are miracles, improving quality and life prolong.A need in his if big that in 1 perc of young, and 2.5 perc. of adult diagnosing a critique, life treating destroying heart rhythm..

Our heart is organ miracle, rationality  arranged, and self-sufficient .He  is  works  all life, without  taking paty, and having a few levels of protection for life-saving. A frequency for heart shortenings is individually and depending on from weight, nationality, constitution, life mode, and  profession. In babies heart  shortening with frequency on 140-180 hits/min, in adult in normally on 60-80. A frequency heart shortenings are less on 60 hots/min, is bradycardia calling, higher on 90-100 is tachycardia. A heart has an own elector  system, which allowing beating his and managing for frequency heart shortenings.He  is  a having importance and secondary elector  station is sinus nodule and atrioventricular nodule, from a which going are lots transferring ways are wires.A when you are healthy, drivers of rhythm  works in pair :sinus nodules with a frequency generates impulses, which goes on atriums, and after in atrioventricular nodule. And he is transferring an elector sign on ventricles, in results they are shortening. And if sinus nodule is failure, and not waited sign from fellow, taking all his function. Pulse is here not rises till 30-40 hits/mint, thus its bad, but system keeping working. A reason for rare rhythm is a syndrome of weakness sinus nodule, where is disease,is sinus  nodule staying lazy, and generating elector impulses are slowly, and sometimes he is forgetting about an own work, and so beginning pause, on a time of which heart stopping on a few sec. First organ, reacting on a blood failure is head brain, of a non-adequate his supply by oxygen in a human having fast weakness, dizziness, dark in eyes, and sense leaves. And these episodes in medicine calling as attacks by Morgan-Adams-Stocks by doctor s names, described theirs on 200 y.ago.  A second bradycardia reason and sense lost is atrioventricular blockages of 2–3  levels. Elector  impulses blocking on a way from atrial in ventricle on a level of atrioventricular nodule.And in a full his blockage for atrium are shortening in an own rhythm , but ventricles in a very rare.
