1,
Remember life is one hundred good words - Qzone lo, the normal ECG: Needless to say, it may be to those few waves and have cut a lead down a wave gives you every 3 cycles, divided into a few lines you see, pay attention to
2 , left ventricular hypertrophy: Just look at V5 is more than 5 cells, is also up and down the vertical left side 5 grid +
3, right ventricular hypertrophy: Just look at V1 is greater than 2 cells, is down to 2 vertical grid ; + right side
4, atrial fibrillation: different size f wave; R - R is absolutely missing
5, sinus bradycardia: each cardiac cycle is greater than five cells ( is the horizontal grid around)
6, sinus tachycardia: each cardiac cycle is less than three cells (which is so cell) compared with the array on the P wave velocity
7, atrial contraction: for some of the normal wave, then a boys and girls, before (Note: This wave of the QRS-T shape is normal, just ahead of Bale, but with different interior was M-type conduction v1 wave,
The Interview With God - Qzone log, QRS can also be widened), it follows that the normal waves is P '(most of the compensation does not fully)
8, ventricular contraction: for some of the normal wave, then a boys and girls, before (note that : At this time large abnormal R waves), it follows that the normal wave
is no P, T and opposite the main wave (mostly compensated fully)
9, typical of myocardial ischemia: V456 ST-segment depression; elevation: v12> 0.3mv v3> 0.5mv v45> 0.1mv
10, acute myocardial infarction: Q wave arched upward widening + ST segment elevation, note: see anteroseptal V123; anterior to see V456; under the wall to see ��, ��, aVF wall, ��, v56, aVL
11, the battle speed: each cardiac cycle is less than two cells,
Farewell World of Warcraft ~ ~ - Qzone log, rhythm rule, QRS normal, no P, T
12,3 degrees block: P frequency> QRS frequency, P-P <RR
