know your heart - the conductive system... memang susah nak faham topic ni..tapi menarik untuk di fahami...

1. INTERPRETATION - BASIC ECG

2. ANATOMI JANTUNG

6. Conductive system of the heart

8. WAVE FORM

9. NORMAL WAVE

10. PR INTERVAL QRS COMPLEX T WAVE ST SEGMENT

11. STEP BY STEP ELECTRICAL ACTIVATION OF THE HEART AND ECG

18. Depolarization : Electrical impulse begin spread Repolarization : Recovery phase will produce electric changes ( action potential of cells ) Terminology

19. ECG PAPER

20. Y X MASA PERGERAKAN JANTUNG DARI ANTRIUM KE APEKS DLM SAAT ( SEC ) MEWAKILI KEKUATAN TENAGA ELEKTRIK DLM mV

23. INTERPRETATION ECG

24. How to start reading an ECG: 1) Don’t panic!! 2) check Name, Age and Date 3)Voltage (10mm/mV) and Speed Calibration(25 mm/sec) 4) aVR are all inverted…!!!

25. basic ECG: 5) Rhythm 6) Rate= for regular 300 Number of big Squares = for irregular R PEAK TIMES 10.

26. FORMULA FOR CALCULATE HEART RATE FOR REGULAR RHYTHM LARGE SQUARE RATE 1 300 2 150 3 100 4 75 5 60 6 50

28. waves: 7) P wave ( not more than 2 small squares high and 2 small squares wide) 8) PR interval (not more than 5 small squares)

29. 9) QRS complex: ( R wave progression from V1 to V6) (width less than 3 small squares)
