What inspections should the sinus aroused in interest and over and slow be done? 's general knowledge
Can see, cause getting aroused in interest having illness coming on originally slow relevant laboratory check the characteristic.
Rely on the electrocardiogram to check, there are the following manifestation:
1.Sinus P wave shape sinus slow and sinuses aroused in interest differences greater P wave shape is this for because sinus sinus room that the knot when being aroused in interest and getting slower too at the time of tachycardia Department,excitement sent out of it more along in if you can't form under each, spread; And sinus get up, fight head is excited more after lying in sinus room that the knot at the time of tachycardia more to some along before form under each spreading. Though the head of the sinus room knot, end difference only 15mm, because form the characteristics conducted preferably, the so the two one be differenced sinus P wave shape,2, last P wave sinuses getting more normal that be united P of rhythms of the heart is getting low and more flat slightly in wave.
2.The frequency adult of sinus P wave is in conformity with lt; 60 times min, it is usually 40- 59 times min, in 45 more
Time above min. Slow to 35 times min the about one, even there are the reports of 20 times min. lt; 45 times min that serious sinus nature are aroused in interest too slow. The intersection of infant and pre-school children and sinus getting aroused in interest slow heart rate, in 1 being under the age of in conformity with lt; 100 times min, 1- 6 years old, in conformity with lt; 80 times min, in conformity with lt over 6; 60 times min.
3. P-R rooms of period 0.12- 0.25s.
4. follow by one normal QRS wave closely in wave QRS each of wave pieces of P,shape, time limit is getting more normal.
5. wave is normal when being aroused in interest and getting slower too in sinus for T wave, u,it can also getting lower relatively in amplitude in the waves when displaying by T, u wave is often relatively obvious.
6. lengthen in proportion issue among issues of Q-T among Q-T,but issue among Q-Tc, on ranges normal after correcting. Normal Q-Tc =Q-T( s) /Should be less than or equal to 0.42s.
