i just took it today and there was only one question that gave some abnormalities in the lateral leads, so you had to know what artery was most likely occluded. i forgot to go over that stuff, so i kind of lucked out that i remembered a few things, but there defiinitely are some basics everyone needs to know anyhow . . .
Sorry....accidently submitted the post...btw, you may want to check the accuracy of what i post because I am going by straight memory
Leads and part of the heart and artery
Anterior leads (V1, V2, V3, V4)- LAD
Lateral leads (I, aVL, V5, V6)- circ
Inferior leads (II, III, aVF)- right main
Also, know basic arrythmias- afib, aflutter, torsades de pointes
Recognize a PVC
Also know the AV nodal disease in first aid...
First degree AV block- prolonged PR
Second degree AV block
Type I- progressive lengthening of PR until dropped beat
Type II- dropped beats without lengthened PR
Third degree- complete AV block- P waves and QRST not in synchrony
although the P-P interval and Q-Q interval are constant
I dont know if this is important for step 1 but it was for third year...Type II second degree AV block and complete AV block are the only two AV blocks that require a pacemaker....first degree and type I second degree just require observation
