-ECG INTERPRETATION
-HOW TO CALCULATE HEART RATE
-NORMAL ECG
-STEPS FOR EASY INTERPRETATION
* CHECK P WAVE
*CHECK P-R INTERVAL(0.12-0.20SEC)
*CHECK QRS COMPLEX(0.06-0.12SEC)
* CHECK R-R INTERVAL(REGULAR /IRREGULAR)
*CHECK HEART RATE(6 SEC METHOD /CONSTATNT METHOD)
1)6X5=30 big boxes(count the QRS in 30 big boxes x 10 =HR)
2) Take the big boxes between 2 QRS complex.
300/no big boxes=HR
* IDENTIFY THE RYTHEM
