left bundle branch block
Term
Increased height of S wave
Definition
right ventricular enlargement
Term
Increased width of S wave
Definition
right bundle branch block
Term
Increased height of T wave
Definition
hyperkalemia, myocardial hypoxia
Term
Negative or absent P waves with normal QRS and slower rate
Definition
junctional arrythmia
Term
No P waves with wide and bizarre QRS compexes and slow rate
Definition
Ventricular arrythmia
Term
No P waves with wide and bizarre QRS compexes and fast rate
Definition
irritable focus of the ventricle
Term

Definition
ectopic focus in atria
Term
Inverted P wave
Definition
impulse originating from around AV junction
Term
Wide QRS
Definition
impulse originating from Bundle of His or bundle branch block
Term
Long P-R interval
Definition
first degree AV block
Term
P wave not followed by QRS
Definition
second degree AV block
Term
P wave not followed by QRS and P-R interval lengthens gradually then P wave occurs without QRS
Definition
second degree AV block, Mobitz Type I
doesn't need treatment
Term
P waves without QRS, P-R interval is constant and QRS is often abnormal
Can see fixed relationship of 1 P wave for every 3 QRS
Definition
second degree AV block, Mobitz Type II
needs treatment
Term
P-R intervals completely rndom with no connection between P waves and QRS
Definition
third degree AV block
QRS is the escape rhythm
Term
Normal HR, irregular rhythm
PR interval is longer and QRS is normal
Definition
atrial premature complexes
