Question 1

Which remote monitoring feature of implantable cardioverter-defibrillators (ICDs) has been shown in clinical trials to reduce cardiovascular hospitalizations?

Accepted Answer

Automatic wireless transmission of device alerts and diagnostics

Answer

Automatic wireless transmission enables earlier detection of device alerts and clinical deterioration, reducing time to clinical action and hospitalization rates.

Question 2

During cardiac resynchronization therapy (CRT) optimization, which parameter adjustment has the strongest evidence for improving clinical outcomes?

Accepted Answer

AV delay optimization using echocardiographic or device-based methods

Answer

Optimizing the AV delay maximizes ventricular filling time and interventricular synchrony, improving cardiac output and CRT response.

Question 3

An implantable loop recorder (ILR) is MOST appropriate for which clinical scenario?

Accepted Answer

Evaluation of unexplained recurrent syncope after non-diagnostic short-term monitoring

Answer

ILRs provide continuous monitoring for up to 3 years and are the preferred tool when shorter monitoring has failed to capture unexplained syncope.

Question 4

A patient with a subcutaneous ICD (S-ICD) develops hemodynamically stable, sustained monomorphic ventricular tachycardia at 160 bpm. The S-ICD CANNOT deliver which therapy?

Accepted Answer

Anti-tachycardia pacing (ATP)

Answer

The S-ICD lacks transvenous leads and therefore cannot deliver anti-tachycardia pacing, which requires intracardiac pacing capability.

Question 5

Which ambulatory cardiac monitoring modality maximizes the likelihood of correlating patient symptoms with an ECG rhythm in a patient with weekly palpitations?

Accepted Answer

Patch-based extended Holter monitor worn for 2–4 weeks

Answer

Extended Holter patch monitors provide continuous multi-week recording, maximizing the probability of capturing symptomatic events that occur less than daily.
