-AF w/ RVR - Irregularly irregular conduction, competition b/twn intrinsic and paced beats.-Frequent PVCs -Intrinsic rate faster than MTR - CORRECT ANSWER: What can can reduce BIV pacing percentage?

<1.5V - CORRECT ANSWER: A shock might not be initiated if the ICD battery voltage falls below what voltage?

> 3 secs. - CORRECT ANSWER: How long must a recorded pause on an IRL last for an asymptomatic patient to warrant a pacemaker?

>98%. - CORRECT ANSWER: Recent studies have shown that the actual percentage

of BIV pacing required of CRT response is:

1) New onset AF.2) AF Burden and duration of episodes.3) Ventricular rate during episodes.4) Impact of medication and other treatment. - CORRECT ANSWER: If at follow up you find episodes of AF, what should you report to the physician?

12-125ms - CORRECT ANSWER: Generally what is the programmable range of

PVAB?

135 bpm. - CORRECT ANSWER: A patient with a dual chamber pacemaker implanted

for 3rd degree HB has the following settings: PAV = 120 ms, SAV=120 ms, PVARP=325

ms and a MTR of 130bpm, at what rate could the patient experience 2:1 block?

3.2V - CORRECT ANSWER: What is the approximate beginning of service (BOS)

voltage of Silver Vanadium Oxide based ICDs?

A composition of Lithium Iodine. - CORRECT ANSWER: Typically what chemical

composition is used in modern day pacemaker batteries?

A drop in systolic blood pressure of >20 mmHg when turning pacing on. - CORRECT ANSWER: A common sign of pacemaker syndrome is:

A waves are greater than E waves. - CORRECT ANSWER: What is true regarding E

and A waves in a healthy heart?

• / 2

abnormalities in cardiac rate or rhythm. - CORRECT ANSWER: Dysrhythmia

Acute phase of lead implant (within 3 months). - CORRECT ANSWER: A lead

dislodgement is most likely to occur when?

AF w/ RVR

Causes competition between intrinsically conducted beats and pacing, leading to a decrease in BIV pacing percentage. Any type of heart block will lead to less intrinsic

conduction and more BIV pacing. - CORRECT ANSWER: What rhythm would most

likely cause a decrease in BI-V pacing?

Alerts allow for earlier detection of problems, therefore allowing more effective

treatment. - CORRECT ANSWER: How does remote monitoring improve survival?

Aluminium.

*Dielectric cracks or imperfections in the foil open up. This allows charge to 'leak' out.Imagine trying to fill a bathtub (capacitor) with the plug out. The time taken to fill the tub (charge time) is longer. Putting the plug back in (fixing the dielectric cracks) reduces fill

time. Fix the cracks by running a 'capacitor reform'. - CORRECT ANSWER: Which

capacitor material requires periodic charges and why?

Amiodarone - CORRECT ANSWER: Which drug is the most commonly used

antiarrhythmic?

Approx 2.8V. - CORRECT ANSWER: What is the approximate beginning of service

(BOS) voltage of Lithium Iodine based pacemakers?

AS VS AS VP AP VP

AP VS - CORRECT ANSWER: What are the 4 modes of DDD pacing?

Atria, atrioventricular - CORRECT ANSWER: Cannon A waves are caused when the

________ contract against closed _______ valves.

Atrial and Ventricular based timing. - CORRECT ANSWER: Hybrid based timing is a

combination of what?

Atrial based timing.

*Once a loss of AV conduction occurs it then switches to ventricular based timing. -

CORRECT ANSWER: Hybrid based timing uses predominantly what style of timing?
