Question 1

Answer 1

right atrial enlargement

RIGHT ATRIAL ENLARGEMENT (RAE)
– P – pulmonale peaked P wave with amplitude greater than .25 (2.5 mm) mv in leads II, III, AVF and greater than .1 mv in leads V1 & V2
– P wave has a slight rightward axis

Question 9

Answer 9

RIGHT ATRIAL Abnormality (overload) (RAE)
– P

– pulmonale peaked P wave with amplitude greater than .25 (2.5 mm) mv in leads II, III AVF and greater than .1 mv in leads V1 & V2

– P wave has a slight rightward axis

Question 11

Answer 11

right atrial enlargement

Question 12

Answer 12

RAE

Question 13

p wave tall, pointed; taller in III than in I

Answer 13

RAE, pulmonale

Question 14

p wave wide, notched; taller in I than in III

Answer 14

P – mitrale
– 2nd half of P wave negative in V1 or III

Question 15

the most common intraventricular conduction defects.

Answer 15

Left Anterior Fascicular Block (LAFB‐KH)

Question 16

Answer 16

• Left atrial enlargement (LAE)
• P‐mitrale “M” signs to P wave
• broad, notched P wave
• p wave duration .11 sec
• p wave amplitude of terminal negatively directed
  
  • portion in V1 greater than .1 mV or 1 mm deep
  • .04 sec wide with slight axis of P wave

Question 17

Answer 17

LAFB

Question 18

Answer 18

Bifascicular Block: RBBB + LAFB‐KH

Question 19

left posterior hemiblock (LPH) criteria

Answer 19

Right axis deviation (RAD) usually ≥ + 120 degrees)

– Small R in leads I and AVL
– Small Q in leads II, III, AVF
–S1Q3 (SinIandQinIII)
– No evidence of RVH

Question 20

Answer 20

posterior hemiblock

Question 21

Answer 21

posterior hemiblock
