Facilitates the insertion of a pacemaker

Assesses the function of the SA node

Evaluates the effectiveness of prescribed antiarrhythmic medication

Identifies the location of abnormal sites within cardiac muscle

Treats certain arrhythmias through the process of ablation

Answer and Explanation

Correct Answer : B,C,D,E

A. Facilitates the insertion of a pacemaker: This is not the purpose of an electrophysiology study (EPS). A pacemaker may be considered based on the results, but EPS itself does not insert the device.

B. Assesses the function of the SA node: EPS is used to assess the electrical activity of the heart, including the function of the SA node.

C. Evaluates the effectiveness of prescribed antiarrhythmic medication: EPS can help evaluate how well antiarrhythmic medications are controlling arrhythmias.

D. Identifies the location of abnormal sites within cardiac muscle: EPS is often used to locate areas of the heart responsible for abnormal electrical conduction and arrhythmias.

E. Treats certain arrhythmias through the process of ablation: One of the therapeutic purposes of EPS is to perform ablation, which can treat certain arrhythmias by destroying abnormal tissue.

Correct Answer is D

Explanation

A. Administration of prescribed Atropine. Atropine is typically used for bradycardia related to second-degree heart block Mobitz 2 or complete block, but Mobitz 1 usually resolves on its own and does not require atropine unless symptoms develop.

B. A prescription for transcutaneous pacing. Transcutaneous pacing is typically used for more severe types of heart block, such as Mobitz 2 or third-degree block, not Mobitz 1.

C. An extra dose of digoxin will be prescribed. Giving additional digoxin would be contraindicated due to its effects on AV conduction.

D. The next dose of digoxin will be held: Second-degree heart block Mobitz 1 (also known as Wenckebach) can be worsened by digoxin, which has a vagomimetic effect that can slow conduction through the AV node. Therefore, the next dose of digoxin should be held to avoid further exacerbating the block.

A. Suppresses ectopic ventricular sites B. Increases SA node automaticity C. Increases myocardial contractibility D. Decreases AV node conduction

Correct Answer is B

Explanation

A. Suppresses ectopic ventricular sites: Atropine primarily increases heart rate; it does not directly suppress ectopic ventricular activity.

B. Increases SA node automaticity: Atropine blocks the parasympathetic nervous system, increasing SA node activity and heart rate in cases of bradycardia or asystole.

C. Increases myocardial contractility: This effect is more related to drugs like inotropes (e.g., dopamine), not atropine.

D. Decreases AV node conduction: Atropine actually increases conduction through the AV node by blocking vagal stimulation.
