BASIC ECG
- 1. INTERPRETATION - BASIC ECG
- 4. WHAT...APA ITU ECG? ELECTROCARDIOGRAM Merakam tenaga elektrik yang dihasilkan oleh jantung
- 5. 2 TYPE MYOCARDIAL CELL 1. Electrical cells :- * Pacemaker cells : specialize electrical cells, had ability to generate impulse * Conduction system 2. Myocardial ( Working ) Cells * Mechanical pump cells
- 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
- 12. ELECTRICAL ACTIVATION OF THE HEART AND ECG A. SINUS IMPULSE ACTIVATES RT ATRIUM AND REACH THE NODES
- 13. ELECTRICAL ACTIVATION OF THE HEART AND ECG B. LT ATRIUM AND AV NODE HAVE BEEN ACTIVATED AND P WAVE COMPLETED.
- 14. ELECTRICAL ACTIVATION OF THE HEART AND ECG C. PURKINJE SYSTEM IS ACTIVATED (A SILENT ECG EVENT )
- 15. ELECTRICAL ACTIVATION OF THE HEART AND ECG D. WHEN THE SEPTUM ACTIVATE
- 16. ELECTRICAL ACTIVATION OF THE HEART AND ECG E. MYOCARDIUM IS ACTIVATED FROM THE ENDOCARDIUM TO THE EPICARDIUM
- 17. ELECTRICAL ACTIVATION OF THE HEART AND ECG F. ST SEGMENT AND THE T WAVE - MEANS VENTRICULAR REPOLARIZATION
- 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
- 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
- 27. FORMULA FOR CALCULATE HEART RATE FOR IRREGULAR RHYTHM 1. COUNT THE NUMBER OF QRS COMPLEXES WITHIN 6 SEC. MULTIPLY THE NUMBER BY 10.
- 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)
