what does lead one and AVL show
high lateral aspects of the heart
what does leads two, three and AVF show
inferior aspects of the heart
what does leads v1 and v2 show
septal
which two aspects does lead v2 show
anterior/ septal
what aspect does leads v2, v3 and v4 show
anterior
what does leads v5 and v6 show
lateral
which leads show lateral aspects
1, avl, v5, v6
which leads show inferior aspects
2,3, avf
which leads show anterior aspects
v2, v3, v4
which leads show septal aspects
v1. v2
how can you rememeber the leads (mnemomic)
like in iceland, line in spain, some awesome ass anal louise lane
what is a normal rate
60-100 bpm
what could less than 60 bpm indicate
sinus brady or junctional bradycardia or slow af or heart block
what could greater than 100 bpm indicate
sinus tachy or junctional tachy or SVT
how long should a pr interval be
0.12-0.20s (3-5 small squares)
how long should qrs be
0.04-0.12s 3 small squares
how long should a qt interval be
0.36-0.47s
what is 1. of 10. point plan for assessing ecgs
waves are predominantly negative in aVR
what is 2. of 10. point plan for assessing ecgs
the ST segment is isoelectric, except in v1 and v2 where it may be elevated but not by >1mm
what is 3. of 10. point plan for assessing ecgs
the PR interval should be 0.12-0.2 seconds (3-5 small squares)
what is 4. of 10. point plan for assessing ecgs
the QRS complex should not exceed 0.12 seconds (3-5 small squares)
what is 5. of 10. point plan for assessing ecgs
the QRS and T waves should be in same direction in the limb leads
what is 6. of 10. point plan for assessing ecgs
the R wave in the chest leads grows from at least v1-v4
what is 7. of 10. point plan for assessing ecgs
the QRS is mainly upright in leads 1,2 and AVF and each QRS is associated with a P wave
