The sinus room of the morbid state forms _'s symptom of diagnostic standard of syndrome

The sinus room of the morbid state forms _'s symptom of diagnostic standard of syndrome
" Chinese internal medicine magazine " invited relevant experts to discuss and make the standard as follows in June of 1977:
1.Disease, sinus syndrome
( 1) The main basis is depleted for the function of the sinus room knot, are shown as one or several items the following three items, and but except is medicine, nerve or supersession disorderly in function some,etc. for person who cause Block of sinus room. The sinus is parked and fought ' Stop above time lasting 2s) . Obvious, for a long time ( Intermission or continuation) The sinus is aroused in interest and too slow ' The heart rate is often under 50 times min) ,The great majority, at the same time yes And/or . Single sinus the too slow one aroused in interest, need to be proved the heart rate can't be increased fast (less than 90 times min) normally by the atropine test .
( 2) As secondary basis, arrhythmia that the companion sends, on the basis of main basis, there can be the following and behave, the popping atrium quivers or flutters the room ' Or handing over) Tachycardia, while breaking out and stopping, it is apt to present longer intermittence before resuming sinus rhythm of the heart. This kind of case is often known as tachycardia - slow syndrome aroused in interest ' Fast - slow syndrome) . Some cases are turned into a chronic atrium and quivered or fluttered after one period. Function obstacle in the juncture district. It is relatively common to fight the function obstacle in order to get up, is shown as the juncture (forming) Fight and take place above 2s after intermittent in ease, or the juncture frequency of rhythm of the heart is under 35 times min; Can also present 2 - one degree of atrio-ventricular block. This kind of situation is known as sometimes " One pair of forming pathological changes " .
( 3) In a few cases, diagnose the basis is: The chronic atrium is quivered or fluttered, there are reliable materials that prove that there were persons who forms main basis with depleted function of the above-mentioned sinus room in the past; Turn, reply by electricity ' Or the medicine rotates and replies) ,Resume the person who appears this kind of manifestation after sinus rhythm of the heart. The lasting, slow juncture rhythm of the heart, the heart rate is often under 50 times min (the sinus room form lasting stopping) ,Can increase fast slightly disconnectedly sometimes.
2.Suspicious disease, sinus syndrome
( 1) Chronic room quiver and room rate unhappy ' The non- medicine causes) ,And the cause of disease is not clear, or the sinus room forms and resumes time to exceed 2s when the electricity is transferred to and replies, and can't maintain sinus rhythm of the heart.
( 2) The sinus is aroused in interest and too slow, most time heart rate is under 50 times min, atropine is tested (1) ; And/or the sinus stops fighting and stopping time and is inferior to 2s.
( 3) Decline under the situation in sport, hyperpyrexia, sharp pain, three heart, it is soon obvious less than normal response for heart rate to increase, atropine is tested at ordinary times ' One) .
3.Explanation
( 1) Disease sinus syndrome a chronic case generally ' Including persons who leave over after acute myocardial infarction) ,But is known as acute disease and sinus syndrome in more transient morbid state of acute myocardial infarction or acute myocarditis sometimes.
( 2) "obvious, for a long time ( Intermission or continuation) The sinus is aroused in interest and too slow " ,Sinus rhythm of the heart is less than or equal to for 50 times min within most time in 24h, even and also fast to 60- 70 times min.
