ANSWERS (100% CORRECT) | LATEST EXAM UPDATE
- Absent P-wave
- Irregular Pulse
- HR > 100-200 bpm - CORRECT ANSWER - Atrial Fibrillation
- Rapid HR
- 240-350 bpm w/ a saw tooth pattern
* Type I 240-350
* Type II >350 - CORRECT ANSWER - Atrial Flutter
*Bizarre QRS.
-Sometimes looks like an upside down QRS - CORRECT ANSWER -
Premature Ventricular Complexes (PVC)
- HR >100bpm
- Large, wide, undulating waves
- P waves are not associated w/ the QRS complex - CORRECT ANSWER -
Ventricular Tachycardia
- Quivering and lack of effective contraction
- ECG is rapid and erratic w/ no identifiable QRS complex - CORRECT
ANSWER - Ventricular Fibrillation
- P - wave is normal
- *** PR interval prolonged (>0.20 sec)
,- QRS will be normal (0.06-0.10 sec) - CORRECT ANSWER - 1st Degree
Heart Block
- P wave is normal
- PR interval is progressively longer (>0.20 sec)
- ***QRS complex will usually be normal (0.06-0.10 sec) UNTIL IT IS
MISSED, then the cycle repeated - CORRECT ANSWER - 2nd Degree Heart
Block (Type 1)
- P wave is normal *** can and often does outnumber QRS complex
- PR interval is normal or prolonged (>0.20 sec)
- QRS complex will be normal or wide - CORRECT ANSWER - 2nd Degree
Heart Block (Type II)
What wave is normal for it to not be there on an EKG? - CORRECT
ANSWER - Q Wave
What does the P wave represent? - CORRECT ANSWER - atrial
depolarization (atrial contraction)
Where does the P wave originate? - CORRECT ANSWER - SA node
What does the QRS complex represent? - CORRECT ANSWER - ventricular
depolarization (contraction)
How long is the PR interval? - CORRECT ANSWER - 0.12-0.20 seconds (3-5
small boxes)
*Measure from the beginning of the P wave to beginning of the QRS
How long is the QRS complex? - CORRECT ANSWER - 0.10 seconds or less
, *Measure from the beginning of the QRS to end of QRS
How long is the QT interval? - CORRECT ANSWER - ≤ 0.40 seconds
*Varies according to the rate. Measure from the beginning of the QRS to the
end of the T
What are sinus rhythms? - CORRECT ANSWER - rhythms that originate in
the SA node
What are the characteristics of sinus bradycardia? - CORRECT ANSWER -
Rate: <60
Rhythm: Regular
P waves: Upright, look alike, one for every QRS
PRI: Normal
QRS: Normal
What are the characteristics of sinus tachycardia? - CORRECT ANSWER -
Rate: >100 <180
Rhythm: Regular
P Waves: Upright, look alike, one for every QRS
PRI: Normal
QRS: Normal
What are the characteristics of sinus block? - CORRECT ANSWER - Rate:
Usually 50 - 80s
Rhythm: Irregular
- Measure R - R after the pause - does it come right back onto the R wave?
