Flashcards in UW ECG Course Deck (14):
Inferior wall MI
left ant. Fascicular block
Lateral wall MI
left post. Fascicular block
How do you assess for LVH?
S wave in V1 OR V2
AND R wave in V5 or V6 > 35mm (small boxes) aka 7 big boxes
1 mm = 1 small box = .04s
5 mm = 1 large box = .2s
How do you asses for RVH?
R wave > S wave in V1 and gets overall smaller as you move to V6
What is the J point?
Point where ST elevation off the baseline
What is a pathological Q wave?
Downward (negative deflection) very big
PR interval should be less than?
< .4 ?
What is a 1st degree AV block?
PR > .2 but NO dropped beats
What is a 2nd degree AV block (Wenckeboch)?
Increasing PR interval before dropped beat
What is a 3rd degrees AV block?
Atrial rate independent of ventricular rate
No pattern bw P wave and QRS
P waves with different sizes and PR intervals indicates what?
Seen in what?
Wandering pacemaker aka Multifocal atrial tachycardia
What is a premature junctional complex?
No P wave visible, occurs in the QRS
Narrow, comes from ventricles
What is a RBBB?
What else is required?
Rabbit ears, R, R’
Inverted T wave
