Cardiac Implantable Devices – Post Test

A 67-year-old woman has an ejection fraction of 28%, resting LBBB on the ECG, and is in NYHA Class III heart failure despite optimal medical treatment. Which one of the following should be her clinical response rate to implantation of a CRT device?

For an active patient with prior syncope, intermittent profound sinus bradycardia and occasional Mobitz Type II heart block, which one of the following is the most appropriate pacemaker mode?

An-80-year old man with prior ischaemic heart disease and an ICD in situ presents to the ED with recurrent non-syncopal rapid palpitations. The bedside monitor shows intermittent salvoes of non-sustained ventricular tachycardia. Approximately how likely is anti-tachycardia pacing (ATP) to terminate a sustained episode?

For the majority of patients, left ventricular pacing in CRT devices is achieved with which one of the following?

A 23-year-old man with an ICD in situ following a diagnosis of Brugada Syndrome with episodic syncope presents with a rapid sequence of internal shocks whilst conscious. A magnet placed over the device is likely to do which one of the following?

If a patient with a device set to a lower rate limit (LRL) of 50 bpm is in normal (unpaced) sinus rhythm at 47 bpm, which one of the following is the most likely explanation?

A 72-year-old woman with a history of recurrent syncope presents after a further episode. A dual chamber pacemaker was implanted 7 weeks previously. Which one of the following is the finding most suggestive of a problem with the device function?

In which of the following X-rays does the yellow arrow indicate a defibrillator lead?

A 69-year-old man with previous ischaemic heart disease, surgical coronary revascularisation and impaired left ventricular function has an ICD implanted for primary prevention. Which one of the following is the most common indication for the ICD to deliver anti-tachycardia therapy?

A patient attends the ED having suffered a severe episode of epistaxis. You have access to previous hospital notes, which contain a reference to intermittent ventricular over-sensing on a pacing check two weeks previously. This is likely to be manifested on the ECG by which one of the following?
