ECGs High Yield Flashcards
Wolff-Parkinson-White
delta waves- a slight up slanting of the QRS
A-fib
- no p-waves
- irregularly irregular
atrial flutter
- no p waves
- sawtooth pattern
pulmonary embolism
- s1 –> deep s wave in lead i
- q3 –> deep q wave in lead III
- t3 –> inverted t wave
hypokalemia
-prominent u wave that is bigger than the T wave
hyperkalemia
-peaked t waves
pericarditis
-diffuse st segment elevation and diffuse pr depression in lead 2
multifocal atrial tachycardia
- fast HR
- due to atrium originating in diff areas
- 3 or more diff P wave morphology
- at least 3 waves must look differently
1st degree av block
a block in the conduction system from sa to av node so the his/purk never gets activated correctly
- all you have here is constant prolonged p-r intervals
- normal pr interval is less than 5 boxes
2nd degree av block mobitz type 1
wenkebach
pr interval gets progressively longer
before a qrs is dropped
-LONGER, LONGER, LONGER, DROP THAT IS A WENKEBACH
2nd degree av block mobitz type 2
- a CONSTANT pr interval elongation
- then a beat is dropped
- like a first degree block with a qrs drop
3rd degree av block
- when the atria and ventricles contract independently of one another
- constant p-p intervals
- constant q-q intervals
left bundle branch block
-wide qrs!
negative in V1
right bundle branch block
-wide qrs!
positive in V1
wide qrs most likely means…
bundle branch block
