ECG Flashcards
V1 V2
septal view
V1 V2 V3 V4
anterior view
L1 aVL V5 V6
left lateral
L2 L3 aVF
inferior
V7-V9/inversion of anterior view
posterior view
2 shockable rhythms
ventricular fibirlalation or ventricular tachycardia
cannot shock someone with
asystole
SA
70-80 bpm
Av
40-60 bpm
purkinje
15-40 bpm
Lateral/left heart = aVL, L1, V5, V6.
Left circumflex artery
Inferior heart = LII, LIII, aVF. `
right marginal artery/Right coronary artery/right posterior descending (PIV)
Anterior heart = V1, V2, V3, V4.
Left anterior descending artery
atrial flutter
saw tooth-
or one big one, then lots of little ones (like 2 or 3 )
atrial fibrilation
irregularly irregular
ventricular ectopic
random really high n weird qrs
ventricular fibrillation
its gone nuts
big and small and skinny
right atrial hypertrophy
peaked p wave
left atrial hypertrophy
bifid p wave
right bundle branch block
M in V1
W in V6
left bundle branch block
W in V1-one big down one up
M in V6
1st degree AV block
PR longer than normal n stays like that
more than 3-5 mini squares
2nd degree type 1 AV blcok/MOBITZ 1/WENKEBACH
longer longer longer drop
mite not seem longer, so just p qrs p qrs p qrs p no qrs, repeat
2nd degree type 2 /mobitz 2
no pr still normal
but random drop of QRS
3rd degree block
p doing own thing, qrs doing own thing
wolf parkinson white syndrom
delta wave pr shortened (less than 3-5 ss)
ventricular tachycardia
big stuff
mostly big stuff
acute anterior myocardial infarction (stemi
tall stuff in V1 V2 V3 V4
hyperkalaemia
peaked T in all leads
hypokalaemia
T wave flattening/inversion, appearance of U wave
after QRS, there is dip
old MI
deep q wave (pointy down thing) in V1 V2 V3
Wide/deepQwavesonlywithoutSTsegmentelevationsignifyan OLD myocardial infarction
A negative deflection on an ECG is caused by either:
Depolarisation moving away from the recording electrode
Repolarisation moving toward the recording electrode
