Ecg Flashcards
Atrial Re polarisation can be seen as
Doesn’t show a wave
What does peaked t wave indicate
Ischaemia in endocardium
What does inverted t wave indicate
Ischaemia in epicardium
What is a q wave
Shows early ventricular depolarisation
Large or prolonged q waves seen in lead directed towards infarction
Anterior leads are
V1, V2, V3 and V4
Which blood vessels supply anterior
Left anterior descending artery
LAD
Lateral leads are
Leads 1
aVL
V5
V6
Which arteries supply lateral leads
Circumflex
Or
Lateral branch of LAD
In lateral mi where are the reciprocal changes
In inferior leads
Lead 2,3 and aVF
Inferior leads are
Leads 2, 3 and aVF
What is inferior leads supplied by
Right coronary artery
Which leads are reciprocal in inferior STEMI
High lateral leads
Leads 2 and aVL
What is a 1st degree heart block
PR intervals are prolonged due to a delay in conduction
Second degree Av block type 1
PR interval becomes longer till one is blocked and there is no qrs
What is Second degree at block type 2
There is more p waves than QRs
