1. LBBB - correct answer - QRS complex greater than 0.12, deep S wave
in leads V1 V2 V3, Broad/notchedr wave is leads V5 & V6
2. RBBB - correct answer - QRS complex greater than 0.12, large/notched
R wave in leads V1 & V2 also slurred S wave lateral leads , I, V5& V6
3. BBB A priority for the provider - correct answer - determine if any
symptoms associated with the BBB and if the block is new
4. New onset BBB concerning for - correct answer - myocardial infarction
5. LBBB causes - correct answer - myocardial infarction, coronary artery
disease, valvular disease such as aortic stenosis, cardiomyopathies,
myocarditis, hyperkalemia, and digoxin toxicity
, Page |2
6. RBBB causes - correct answer - heart disease secondary to
hypertension, myocardial infarction, myocarditis, cardiomyopathies,
COPD, cor pulmonale or right sided heart failure, & PE
7. NSR - correct answer - HR 60-100 with P wave before every QRS
complex followed by a T wave. The PR interval and QRS complex will
measure normal and will be the same for each beat
8. Sinus bradycardia causes - correct answer - sick sinus syndrome,
digoxin and beta blockers, hypothermia, hypoglycemia, hypothyroidism,
CAD
9. Sinus tachycardia - correct answer - is a rate > 100 beats per minute
10. Sinus tach causes - correct answer - fever, anxiety, hyperthyroidism,
medications such as albuterol and dobutamine, anemia, pain
11. Decreased cardiac output - correct answer - responsible for the
symptoms patients may present with
12. PAC - correct answer - delay to the next sinus beat which allows for
increased filling of the ventricles prior to the next contraction. Rhythm is
irregularly, irregular. No P waves = No PR interval
, Page |3
13. Heart 4 chambers - correct answer - Right and Left atrium & Right
and Left ventricle
14. Perfusion to the various chambers of the heart is via - correct answer
- RCA & Left main descends into LAD (left anterior descending artery)
15. RCA supplies blood to - correct answer - RA, RV, SA (sinoatrial
node) & AV (atrioventricular node)
16. LAD supplies blood to - correct answer - L front side of the heart
17. L circumflex artery supplies - correct answer - to left outer side as
well as posterior side of the heart
18. Both the LAD & RCA supply blood to - correct answer - the septum
19. Cardiac contraction happens when - correct answer - depolarization
of the heart
