What does the sinus aroused in interest produce the mechanism slowly? What characteristics does the electrocardiogram have? 's general knowledge
Sinus room form, get up, fight cell 4 phase, eliminate, polarise, rise degree slow down, the slope is diminished automatically, a film electric potential level of biggest relaxation is shifted down and moved at the threshold potential level, can cause the sinus cardiac cycle to lengthen, so that the sinus aroused in interest and too slow appears.
Organism oxygen consumption is reduced, the discharging amount of heart increases, it is aroused in interest and too slow to cause the sinus through the reflectivity of excited nervus vagus.
Sinus room form, get up, fight cell to be ischemic taking, can cause the intersection of sinus and room form self-disciplining, reduce by oxygen deficiency, inflammation, fiber, the sinus aroused in interest and too slow appears.
Electrocardiogram characteristic:
1.Possess the electrocardiogram characteristic of the above-mentioned normal sinus rhythm of the heart.
2.The heart rate: Adult every and 60 time following minute ' But generally in every minute 40 or more times) ,Children one is less than it 80 times every minute, infancy every minute is less than for 100 times.
3.Unless movement, excitement or injecting behind atropine, can make by heart rate, be accelerated gradually,after slow down gradually. But in some old persons' pathology sinus is aroused in interest and too slow, accelerate not obviously or accelerating.
4.The sinus aroused in interest and slow is often arrhythmic with the sinus nature.
