From what reason did the block of sinus room caused _ general knowledge
(1) Pathogenic factor
1.Mostly see to the organic heart disease patient Coronary heart disease account for 40% most common cause of disease because cardiac muscle ischemic to cause the intersection of sinus and room form around acute organic lesion the intersection of wall and myocardium the intersection of infarction and their sinus room block incidence for lay, slow much fewer pathogenic factor their can continue, take place room form ischemic or infarction to be also common meeting at even on increase other sinus by the intersection of nervus vagus and tension The sex heart disease and rheumatic heart disease and myocardium disease, congenital heart disease and chronic inflammation or sinus room which is short of due to blood is formed and surrounding tissue pathological change,etc.
2.Potassium high carbonic acid of high blood blood disease and diphtheria influenza,etc.
3.Sinus room form the intersection of regression and sex of district to harden fiber take fat or the intersection of starch and kind change week
4.Medicine (such as one meter of third pyrrole amine amine iodine ketone receptor of handkerchief of foreign digitalis Vera Ding of Kui Nicaragua blocks medicines,etc.) It can also be caused to poison and heavy dose of and use ketone of general Luo's handkerchief 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 intravenous to inject the intersection of sulfic acid and magnesium due to (can't get rid of, inject too fast speed) Low blood potassium ( lt; 2.6mmol/L= can also happen hour
8.A few can coincide atrio-ventricular block present person who go on aggravate, claim pair marry syndrome
(2) Onset mechanism
Person who hand over make the intersection of atrium and skin to around the intersection of atrium and skin except that produce atrium wave namely sinus the intersection of P and wave so as, measure the intersection of sinus and the intersection of room and the intersection of activity and the intersection of sinus and the intersection of room and block and sinus of knot indirectly very much Form, send out excited excited to reach from the intersection of sinus and the intersection of room and person who hand over atrium happen, conduct, delay or can't spread, block for person who spread the former display first at the skin outwards regularly on time still Degree and two degrees type sinus room 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
