Which remote monitoring feature of implantable cardioverter-defibrillators (ICDs) has been shown in clinical trials to reduce cardiovascular hospitalizations?
Answer: Automatic wireless transmission of device alerts and diagnostics
Automatic wireless transmission enables earlier detection of device alerts and clinical deterioration, reducing time to clinical action and hospitalization rates.
During cardiac resynchronization therapy (CRT) optimization, which parameter adjustment has the strongest evidence for improving clinical outcomes?
Answer: AV delay optimization using echocardiographic or device-based methods
Optimizing the AV delay maximizes ventricular filling time and interventricular synchrony, improving cardiac output and CRT response.
An implantable loop recorder (ILR) is MOST appropriate for which clinical scenario?
Answer: Evaluation of unexplained recurrent syncope after non-diagnostic short-term monitoring
ILRs provide continuous monitoring for up to 3 years and are the preferred tool when shorter monitoring has failed to capture unexplained syncope.
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?
Answer: Anti-tachycardia pacing (ATP)
The S-ICD lacks transvenous leads and therefore cannot deliver anti-tachycardia pacing, which requires intracardiac pacing capability.
Which ambulatory cardiac monitoring modality maximizes the likelihood of correlating patient symptoms with an ECG rhythm in a patient with weekly palpitations?
Answer: Patch-based extended Holter monitor worn for 2–4 weeks
Extended Holter patch monitors provide continuous multi-week recording, maximizing the probability of capturing symptomatic events that occur less than daily.
The CHAMPION trial demonstrated that remote pulmonary artery pressure monitoring using an implantable sensor (CardioMEMS) primarily reduced which outcome in heart failure patients with NYHA class III symptoms?
Answer: Heart failure–related hospitalizations
The CHAMPION trial showed a 28% reduction in heart failure hospitalizations through hemodynamic-guided therapy adjustments based on daily PA pressure readings.
When counseling a patient with a non–MRI-conditional pacemaker about electromagnetic interference, the minimum recommended distance between the device and a strong consumer magnet is approximately:
Answer: 6 inches (15 cm)
Most device manufacturers recommend at least 6 inches (15 cm) of separation from magnets to prevent reversion to asynchronous pacing or sensing inhibition.
