The sinus room of the morbid state forms syndrome to diagnose according to _'s symptom
Sustain or the intermittence appears slowly when the sinus rhythms of the heart of 50 times min have concurrently blocking or sinus resting and slow ease of sinus room that fight rhythm of the heart or malposition tachycardia, can diagnose as this syndrome. The sinus room is blocked to only have sinus nature aroused in interest and slow or even now in sinus rhythm of the heart, the junction person who fights ease must follow up a case by regular visits to and observe and can affirm diagnosis. Atrium quiver by treatment and ventricle rate 60 about min or atrium rate need highly suspect this syndrome under 200 times min when atrium flutter only. Guard the dynamic electrocardiogram, can detect the unusual rhythm of the heart neglected at ordinary times, contribute to diagnosing.
Can do the suspicious patient:
Stimulate and test: Or exceed 90 times min if mg. heart rate intravenous injection atropine 1- 1.5 to advise by patient movement and (or) Block the sinus room, sex tachycardia belongs to the masculine gender on the junction rhythm of the heart, room. Use different third Epinephrine ' 3- 5 g intravenous injection) , neostigmine ( 0.3- 0.5mg intravenous injection) Unless last masculine gender also persons who and then not appear on situations the above-mentioned, but it is sure dangerous not to have,should not uses regular.
The sinus room conducts time to determine: Get up to fight and release the room to fight early with the procedure in the artificial atrium, such as is A1- A1s that the sinus room forms and contains cycle by oneself, fight P wave ( A2) early in the room Impulse last room to form to make it not advanced except that very much sinus room junction,and from then on when begin to rearrange by sinus frequency, produce the room and fight the last first sinus P wave ( A3) early . A2- A3 interval calls reply cycle (returning cycle) ,Mean excited to pass sinus to atrium room form and the intersection of sinus and the intersection of room and impulse of knot pass time and the intersection of sinus and room of atrium to, form sum of eigenperiod. The former two's average claims the sinus room conduct time SACT =2 A2A3- A1A1/, normal the intersection of sinus and room that experiment determine conduct time as the intersection of 82 and 19.2ms, supreme limit 120ms> 150ms brief on have sinus rooms conduct the obstacle.
The sinus room forms and resumes time to determine: Get up to fight fast with the artificial atrium, get up to fight frequency 10- 20 times min and increase to for 100- 160 times maintain 1- 2min respectively after min gradually, then monitor and make the unexpected stop atrium in the electrocardiogram and get up to fight, determine sinus room form, resume time activity take after the atrium stops fighting ' Time give, fight signal, get first sinus the intersection of P and distance among the wave never) Called the sinus room and formed and resumed time. Normal about 1s, this syndrome often prolongs to above 1.5s. The aforesaid determines the result in the normal range person; Can't deny and diagnose; Apparent to exceed and have reference value normally.
