Sinus slow clinical diagnosis _'s symptom aroused in interest
Check in electrocardiogram: The frequency of adult's sinus rhythm of the heart is less than for 60 times minute, is called the sinus aroused in interest and too slow. Sinus getting aroused in interest and slow often at the same time following take place arrhythmic sinus nature ' Namely the difference of one is greater than 0.12s among different PP) .
Electrocardiogram characteristic
The slow electrocardiogram characteristic is shown in the following several aspects on the sinus aroused in interest:
1. P wave is formed and sent out in the sinus room " Sinus P wave " ,P the intersection of wave and order appear, P wave lead unite, standing upright in 2, aVF, V3-V5, lead unite, inverting in aVR.
2. It P appears by wave frequency last 60 times /divide,generally at 40- 60 time /during not dividing.
3. One is greater than 0.12 seconds among P-R. T amplitude often on the low side in wave when sinus aroused in interest and too slow, issue than long generally among the Q-T, U sometimes conspicuous in wave.
4. Getting aroused in interest sinus slow the intersection of electrocardiogram and characteristic display in arrhythmic with sinus nature often still.
