Explain everything on the QRS COMPLEX from an ELECTRICAL POINT OF VIEW
( Correct answers ) AV NODE, BUNDLE OF HIS, LT & RT BB, PURKINJE FIBER
Explain everything on the QRS Complex from a PHYSIOLOGICAL POINT OF VIEW
( Correct answers ) 1. LOW 02 BLOOD - > TRICUSPID VALVE - > RT VENTRICLE -
> PULMONARY VALVES - > PULMONARY TRUNK - > LUNGS - > GAS EXCHANGE
2. HIGH 02 BLOOD - > BICUSPID VALVE - > LT VENTRICLE - > AORTIC VALVE - >
AORTIC ARTERY - > WHOLE BODY
, WHAT ARE THE NORMAL VALUES of QRS COMPLEX AND HOW DO YOU MEASURE IT (
Correct answers ) 1. LESS THAN 0.12 SEC
2. BEGINNING OF Q WAVE OR R WAVE IF Q IS NOT PRESENT UNTIL END OF S WAVE
WHAT ARE THE NAMES OF THESE WAVES ( Correct answers ) A) POSITIVE
WAVE/ DEFECTION ABOVE BASELINE
B) NEGATIVE WAVE/ DEFLECTION BELOW BASELINE
EXPLAIN WHAT THE T WAVE REPRESENTS FROM A PHYSIOLOGY POINT OF VIEW
(
Correct answers ) RELAXATION OF THE VENTRICLES
1. RT VENTRICLES: RECEIVES LOW 02 BLOOD FROM RT ATRIUM
2. LT VENTRICLE: RECEIVE HIGH 02 BLOOD FROM LT ATRIUM
HOW DOES THE FLOW OF ELECTRICAL IMPULSE GO FROM THE: SA NODE TO THE
ATRIUM AND FROM THE PURKINJE FIBERS TO THE VENTRICLES ( Correct answers
) SA NODE- TOP TO BOTTOM
PFs- BOTTOM TO TOP
EXPLAIN WHAT THE PRI REPRESENTS AND GIVE THE NORMAL VALUES AND HOW
YOU WILL MEASURE THEM AND THE DEVICE YOU WILL TO ACCOMPLISH THIS
( Correct answers ) 1. REPRESENT: TIME THAT THE ELECTRICAL IMPULSE TAKES TO
TRAVEL FROM THE SA NODE TO THE AV NODE
2 NORMAL VALUE: 0.12- 0.20 SEC
3. FROM THE BEGINNING OF P TO THE BEGINNING OF Q OR R IF Q IS NOT PRESENT
4 DEVICES: CALIPER
