CHEST LEADS.pptx

this ppt is about a type of ecg or electrocardiograph.

1. CHEST LEADS (ALSO CALLED PRECORDIAL LEADS)

2. The positive electrode – exploring electrode the negative electrode- indifferent electrode

3. THE INDIFFRENT ELECTRODES (NEGATIVE ELECTRODE) NEGATIVE ELECTRODE IS CONNECTED TO RIGHT ARM,LEFT ARM AND THE LEFT LEG ALL AT THE SAME TIME THROUGH EQUAL RESISTANCES THIS CREATES VIRTUAL ELECTRODE AT THE CENTER OF THE HEART, AND THAT IS CALLED AS WILSONS CENTRAL TERMINAL (WCT) VOLTAGE IS STEADY AND AMPLITUDE IS NEGLIGIBLE

4. EXPLORING ELECTRODES (POSITIVE ELECTRODES) THESE ARE CHEST LEADS THAT ARE PLACED ON THE ANTERIOR SURFACE OF THE CHEST AT ANY OF THE FOLLOWING SIX LOCATIONS ……

5. V1 ON RIGHT BORDER OF STERNUM , IN 4 TH INTERCOASTAL SPACE ECG POSITION

6. V2 ON LEFT BORDER OF STERNUM , IN 4 TH INTERCOASTAL SPACE ECG POSITION

7. V3 BETWEEN V2 AND V4 ECG POSITION

8. V4 MID-CLACICULAR LINE ECG POSITION

9. V5 ANTERIOR AXILLARY LINE ECG POSITION

10. V6 MID-AXILLARY LINE/ARMPIT CENTRE ECG POSITION

11. THESE ALL CHEST LEADS ARE RELATED TO SOME ACTIVITY OF THE SOME PARTS OF HEART

12. V1 AND V2 SHOWS ACTIVITY OF THE RIGHT SIDE

13. V3 AND V4 SHOWS ACTIVITY OF THE ANTERIOR PORTION OF HEART

14. V5 AND V6 SHOWS ACTIVITY OF THE LEFT SIDE

15. THANK YOU!!!!!
