The sinus room of the morbid state forms clinical diagnosis _'s symptom of syndrome
The sinus room of the early or not typical case may present intermittent outbreak to form the function obstacle, or regard the sinus aroused in interest and too slow as and mainly or only behave, often it is difficult to regard making a definite diagnosis of as this disease, check, contribute to, assess the sinus room, marry the function while being following. The dynamic electrocardiogram is probably recorded to many kinds of characteristic electric charts of heart of SSS now within 24 hours, can be checked repeatedly in a short time when the result is negative. In order to get rid of the influence that the tension of autonomic nerve changes, can do atropines to test (atropine 1- 2mg of intravenous injection) Test with different third Epinephrine ' The vein injects or instils 1- 2 g) ,If the heart rate can't increase the persons who reach 90 times min quickly and brief on the sinus room to form the function low after the note. But negative a result ' The heart rate is increased and got 90 times min or the above) quickly after the note Can't get rid of a evidence. Can also adjust and fight the method to determine the sinus room forms and resumes time (SNRI) in the room diligently Conduct time (SACT) with the sinus room ,Disease the intersection of sinus and syndrome SNRT and SACT of patient often apparent to exceed the normal high limit. The appraisal forming the function in assessing the sinus room with the physiological index of above-mentioned electricity differs, it is generally acknowledged that determines the result can not be denied to diagnose in the normal range, the result is apparent to exceed the normal high limit (such as SNRT exceeds 2000ms) Have reference value. Many people think he diagnoses value is not so good as the dynamic electrocardiogram.
[Electrocardiogram characteristic ]
It include sinus room it form function obstacle the electrocardiograms of the themselves and continue and if you can't take place, if you can't last function not normal ease, fight at sinus room and ( Or) Last rhythm of the heart ease,it can erupt by bursts of arrhythmia fast simultaneously with (or) The electrocardiogram given much trouble in other positions of conducting the system is silent to behave. Sinus room block and ( Or) Sinus resting the sum ' Or) Show the sinus aroused in interest and too slow; Ease fight short burst or escape, fight rhythm of the heart continuously, ease fight, take, obtain, two unite law, visit, move rhythm of the heart; With room fast for arrhythmia,if not frequently if you can't send by room, beat too early. Short burst of atrium quivering, atrium fluttering or room tachycardia that or break out repeatedly that burst is sent, form the so-called slow - fast syndrome (bradycardia-tachycardia syndrome) with the slow sinus rhythm of the heart . Fast rhythm of the heart, after the not normal automatic stop, sinus often on as long as, appear after the intermittence of the above 2 second rhythm of the heart; Room the intersection of room and junction get up to fight sum ' Or) Conduct the intersection of function and obstacle, show as the intersection of room and the intersection of room and the intersection of junction and ease appeared to delay fight, pass slow the intersection of room and the intersection of room and the intersection of junction and ease fight rhythm of the heart (ease fight the intersection of cycle and the intersection of and gt; 1.5s) Or atrio-ventricular block, amalgamate bunch, prop up block while being accidental.
Medical university Zhongshan hospital of Shanghai depends on the dynamic electrocardiogram (DCG) Behave, divide into 4 type: Type,serious but aroused in interest and getting slower too in lasting sinus (21.1%) ; 2Type,park and fight by sinus sinus or block sinus room (30.5%) ; Type,it is slow fast syndromic (12.6%) ; Type,pair sick without being formed (35.8%) . Among them one pair of pathological changes forming type faints or is covered with the incidence wickedly ' 70.6%) Obviously higher than other various. Faint by clinical manifestation or wicked DCG of covering with etc. interval for 0.7 second such as 4.9 , apparent to good at person of symptom had on average. The persons who treat in fighting by getting up follow up a case by regular visits to 9 and a half years on average, showing has quite long natural medical history, there is not a person who dies of this syndrome while following up a case by regular visits to. But Sutton,etc. observe, one year 85%- 92% survival rate, over 7 o'clock.
