Charles Jenkins, a 47 yo male with a history of aortic stenosis, is experiencing weakness, fatigue and decreased exercise tolerance. A cardiac catheterization revealed a 60mm pressure gradient across the aortic valve and calcification of the aortic ring. On POD #2, Mr. Jenkins developed a heart rate of 42 and his BP dropped to 84/20 and respirations were 22. A rhythm strip recorded showed:
- A.
Sinus bradycardia
- B.
Sick sinus syndrome
- C.
Mobitz II
- D.
Third degree heart block
Correct Answer
D. Third degree heart blockExplanation
The given symptoms and findings suggest that Charles Jenkins is experiencing a severe blockage of electrical signals between the atria and ventricles of his heart. This is indicated by the low heart rate (42 bpm) and the significant drop in blood pressure. Third degree heart block, also known as complete heart block, is a condition where there is a complete blockage of electrical signals between the atria and ventricles, resulting in a slow and irregular heartbeat. This condition can cause weakness, fatigue, and decreased exercise tolerance, which are consistent with Charles Jenkins' symptoms.Rate this question:

Mr. Jenkins returned to surgery and had a permanent dual-chamber pacemaker implanted. The following strip was recorded in CTICU. It revealed:
- A.
Normal sinus rhythm
- B.
Left bundle branch block
- C.
P-wave tracking pacing or DDD pacing mode
- D.
Ventricular demand or DVI pacing mode
Correct Answer
C. P-wave tracking pacing or DDD pacing modeExplanation
The strip recorded in the CTICU showed normal sinus rhythm, left bundle branch block, and P-wave tracking pacing or DDD pacing mode. This means that the patient's heart was beating in a normal rhythm, but there was a delay in the electrical conduction in the left bundle branch. The pacemaker was set to track the P-waves and deliver pacing in the DDD mode, which means it was pacing both the atria and ventricles as needed. This mode ensures proper synchronization of the heart's chambers and helps maintain a normal heart rhythm.Rate this question:

NTG post MI has what benefit?
- A.
Increases preload, decreases after load, decreases BP, elevates MVE demand
- B.
Decreases preload, increases after load, elevates BP, elevates MVE consumption
- C.
Decreases preload, decreases after load, elevates BP, decreases MVE delivery
- D.
Decreases preload, decreases after load, decreases BP, elevates MVE delivery
Correct Answer
D. Decreases preload, decreases after load, decreases BP, elevates MVE deliveryExplanation
After a myocardial infarction (MI), the heart's ability to pump blood is compromised. Decreasing preload (the amount of blood filling the heart) and afterload (the resistance the heart has to overcome to pump blood out) helps reduce the workload on the heart and improve its efficiency. Decreasing blood pressure (BP) is important to prevent strain on the heart and reduce the risk of further damage. Elevating myocardial oxygen demand (MVE delivery) is necessary to ensure adequate oxygen supply to the heart muscle. Therefore, decreasing preload, decreasing afterload, decreasing BP, and elevating MVE delivery are all beneficial in post-MI management.Rate this question:

A drug that may cause intra coronary steal away from ischemic areas is:
- A.
Norepinephrine
- B.
Nitroprusside
- C.
Nicardipine
- D.
Enalaprilat
Correct Answer
B. NitroprussideExplanation
Nitroprusside is a drug that may cause intra coronary steal away from ischemic areas. Intra coronary steal refers to the redistribution of blood flow within the coronary arteries, away from areas of ischemia or inadequate blood supply. Nitroprusside is a vasodilator that acts by relaxing smooth muscles in blood vessels, including those in the coronary arteries. This relaxation can lead to increased blood flow to non-ischemic areas, potentially diverting blood away from areas with compromised blood supply.Rate this question:
