1.
All of the following drugs reduce the ventricular rate in atrial fibrillation, except:
Correct Answer
A. Procainamide
Explanation
Kumar page 775, and Dr.Akhtar lecture
2.
Regarding the previous EEG, what's the proper/best treatment:
Correct Answer
C. Amiodarone
Explanation
Amiodarone is the proper/best treatment for the previous EEG. Amiodarone is an antiarrhythmic medication that is commonly used to treat irregular heart rhythms, including ventricular fibrillation and ventricular tachycardia. It works by slowing down the electrical signals in the heart, helping to restore a normal heart rhythm. This medication is often preferred over other options like CD shock or digoxin due to its effectiveness and safety profile.
3.
All of the following are true about Lidocaine except:
Correct Answer
A. Half life is hours
Explanation
Reference:
Dr. Akhtar lecture (antiarrhythmia) - 6th year.
The elimination half-life of lidocaine is approximately 1.5–2 hours in most patients.
Lidocaine undergoes extensive first pass metabolism in the liver.
it is used for the acute management of ventricular arrythmias, especially in patients with myocardial infarction
4.
Regarding paroxysmal supraventricular tachycardia (SVT), which is TRUE:
Correct Answer
E. Digoxin IV reduces paroxysmal SVT rate
Explanation
( Harrison’s principles of internal medicine , 16th edition , table 214-4 , p.1348 )
5.
All of the following will show ventricular rate in atrial fibrillation, EXCEPT:
Correct Answer
A. Disopyramide
Explanation
Answer is: a, according to Dr. A5tar lecture: one of the side effects of class I (quinidine and Disopyramide) is ventricular tachycardia, which is a life-threatening condition. As A. fib is not a life-threatening condition and the quinidine has this serious side effect, it should be avoided. However, if you are willing to give quinidine, give another drug which reduces HR such as CCB or digoxin.
6.
Severe Aortic stenosis criteria:
Correct Answer
C. None of the above
Explanation
this was an incomplete question, the right answer wasn't remembered
from dr Akhtar's lectures..
AS is considered to be severe when:
1. AVOA < 0.8 cm2,
2. Systolic Pressure Gradient Across AV > 50 mmHg
Symptoms in severe cases:
- Low CO symptoms (Syncope)
- Angina
- CHF
- SCD = Sudden cardiac death
7.
All of the following are a feature of tricuspid regurgitation except:
Correct Answer
A. Prominence a wave
Explanation
In TR a wave is not prominant, v wave is the one that will be prominant
8.
Angina pectoris + syncope, can be symptoms of which of the following:
Correct Answer
E. AS
Explanation
In severe cases of AS, a patient can present with both angina pectoris and syncope
Reference: Dr. Akhtar's lecture VHD
9.
All are found in chronic mitral regurgitation ,except:
Correct Answer
B. s4 gallop
Explanation
In chronic MR both left ventricle & left atrium are enlarged. (Davidson 622)
Apex beat is heaving due to left ventricular dilatation. A loud third heart sound (S3) may be present due to sudden rush of blood back into the dilated left ventricle in early diastole (Danish 102)
An S4 gallop is uncommon in chronic mitral regurgitation. However, in acute mitral regurgitation, an S4 gallop is common because the left atrium and ventricle are noncompliant.
So, the most likely answer is S4 gallop
10.
Case: A patient with mitral regurgitation, exercise intolerance, and his left ventricular end-diastolic diameter (LVEDD) is 6.8 cm, how do you manage him?
Correct Answer
A. Do mitral valve replacement
Explanation
Reference:
Cardiology Pocket Book.
Comment:
Surgery is indicated here due to progressive symptoms and valvular damage (normal ventricular end diastolic diameter is 3.5-5.6).
11.
Regarding mitral valve prolapse all are true except:
Correct Answer
C. Late systolic murmur.
Explanation
In MVP there is mid diastolic click in mild cases and pansystolic murmur if significant mitral regurgitation. The click is believed to be produced by sudden tensing of elongated chordae tendineae of prolapsing leaflets
Most patients are asymptomatic. In symptomatic patient it presents as chest pain (atypical), dyspnea, palpitation, syncope and sudden death. chest pain is similar to angina but may last for hours or for days, not related to exertion, and punctuated by brief attacks of severe stabbing pain at the apex.
