cardiac conduction

Question 1

structures involved

Answer 1

sinoatrial node
atrioventricular node
right bundle branch
left bundle branch
perkinjie fibres

Question 2

process of cardiac cycle

Answer 2

electrical impulse is generated at the SA node near right atrium
depolarisation spreads to the AV node at right atrium
slight delay at the AV node allows atria to contract and ventrical to fill
depolarisation wave move into the bundle of his
depolarisation continue to perkinjie fibres for ventricle contraction

Question 3

P wave

Answer 3

depolarisation of SA node

Question 4

the flat line between P and Q is

Answer 4

av node delay

Question 5

QRS complex

Answer 5

depolarisation of both ventricles

Question 6

T wave

Answer 6

repolarisation of ventricles

Question 7

normal rythm

Answer 7

60-100 beats

Question 8

bradycardia

Answer 8

less then 60 bpm

Question 9

tachycardia

Answer 9

more then 100 BPM

Question 10

atrial flutter

Answer 10

rapid atrial rate

Question 11

atrial fibulation

Answer 11

irregular rythm
no P wave

Question 12

supraventricular tachycardia

Answer 12

rapid heart beat

Question 13

1st degree AV block

Answer 13

prolonged PR interval

Question 14

2nd degree AV block mobitz type 1

Answer 14

progressive prolonged PR interval

Question 15

2nd degree AV block mobitz type 2

Answer 15

random QRS consistant PR wave though

Question 16

3rd degree AV block

Answer 16

atria and ventricle beat independent

Question 17

junctional escape rythm

Answer 17

narrow QRS absent P wave

Question 18

idioventricular rythm

Answer 18

wide QRS no P wave

Question 19

ventricular tachycardia

Answer 19

wide QRS fast rate

Question 20

ventricular fibulation

Answer 20

chaotic no organisation

Question 21

pulseless electrical activity

Answer 21

ECG present but no wave

Question 22

aystole

Answer 22

flat line
