Ill machine _'s general knowledge of cause of disease of Dou room of block
Pathogenic factor of the block of sinus room
1.Mostly see it is the most common cause of disease at organic heart disease and patient's coronary heart disease, account for 40%. Because the cardiac muscle is ischemic to cause the sinus room to form the organic lesion around. Acute the intersection of wall and myocardium infarction play, the intersection of sinus and room its it blocks incidence to be 3.5%, aroused in interest and too slow and much fewer than sinus. Its pathogenic factor can be continued and taken place to increase in the tension of nervus vagus, in addition the sinus room is formed ischemically or infarction is also common. In addition see at hypertension heart disease and rheumatic heart disease, myocardium disease, congenital heart disease, chronic inflammation or forming and surrounding tissue pathological change of sinus room which is short of due to blood,etc..
2.High the intersection of blood and potassium, high the intersection of carbonic acid and the intersection of blood and disease, diphtheria, influenza,etc..
3.Sinus room form regression of district for less than week sex harden and fiber take and fat or the intersection of starch and kind change.
4.Medicine ( One meter of third pyrrole amine amine iodine ketone receptor blocks medicines,etc. in the handkerchief of for instance foreign digitalis Vera Ding of Kui Nicaragua) Being poisoned and heavy dose of and used ketone of general Luo's handkerchief can also be caused, but mostly temporary.
5.Can be seen and increase in the tension of nervus vagus or the allergic healthy people of carotid sinus, the available atropine test verifies.
6.It can be the family that a few reasons are unidentified and specific.
7.I haven't seen you for a long time on the intersection of sulfic acid and magnesium due to of injecting while being intravenous ' Can't get rid of, inject too fast speed) Low blood potassium can also happen hour.
8.A few can coincide atrio-ventricular block, present person who go on aggravate, claim pair marry syndrome.
Morbidity mechanism of the block of sinus room
It forms excited electric potential that sends out to be very little to copy, write, produce at the intersection of body surface and electrocardiogram because of the intersection of sinus and room, form the electric picture to record to the sinus room to form the excitement sent out only with the sinus room. Want through the intersection of sinus and the intersection of room and person who hand over to around the intersection of atrium and skin, enable skin of atrium except that produce the atrium wave very much, namely sinus the intersection of P and wave so as, measure the intersection of sinus and the intersection of room and activity of knot indirectly, sinus room block with sinus nature parking, fighting different sinus rooms, marrying, it is excited to still send out regularly on time. But person who hand over reach atrium, conduct and delay or can't spread that block the former for the spreading at the skin outwards from the intersection of sinus and room, display for a time and hinder the persons who lag behind and is shown as the sinus room of two degrees of Model 2 is blocked or three degrees of sinuses room is blocked in the two degrees type sinus room.
