Indications Flashcards
Highlights current AHA indications for Brady, Tachy and CRT therapy. Currently weighted 9% in the CCDS exam.
List the 3 class I indications for SND.
- Symptomatic documented brady / pauses
- Symptomatic chronotropic incompetence
- SND resultant of drug therapy of which there are no alternatives
List the 5 class I indications for AV Block.
- 3rd or 2nd degree AVB + Symptomatic bradycardia
- Pauses >3s or HR <40bpm
- AF pauses >5s
- Post AVN ablation
- Surgical LV dysfunction
What is the one Class IIb indication for SND?
Minimally symptomatic with HR <40bpm during awake hours.
List the 2 class IIb indications for AV Block.
- Neuromuscular diseases
- AV block during drug use where block is recurrent
List the 3 class I indications for bifasicular block.
- Advanced 2nd or intermittent 3rd degree block
- Mobitz II
- Alternating BBB
Which pacing indication class is the following?
‘Asymptomatic CHB with HR >40bpm’.
Class IIa.
What 4 things are typically present in class I ICD indications?
- Survivor of VF or VT
- LVEF <40% due to prior MI
- Recorded or inducible VF/VT
- NYHA class I, II or III
Not necessarily all at the same time.
The phrase ‘‘It is reasonable’’ typically relates to what indication class?
Class IIa.
The phrase ‘‘may be considered’’ typically relates to what indication class?
Class IIb.
List the only class I indication for reflex syncope.
Recurrent 3 second pauses with syncope from CS stimulation.
Yes / No
Does asymptomatic Mobitz II indicate pacing?
Yes.
Has a high risk of progression vs. Mobitz I which is lower risk.
Yes / No
If symptoms are due to AV block, should we permanently pace?
Yes - Class I indication.
True / False
Which class applies?
‘A-pacing is recommended over V-pacing for sypmtomatic patients with SND’.
True - Class I indication.
Which class applies with respect to permanent PPM insertion?
‘SND, Symptomatic, Intact AV conduction, no evidence of conduction abnormality’.
Class I indication.
Either DR or SR pacing is recommended at class I in this instance.
Yes / No
Should this device be programmed to minimise RV pacing (list indication class)?
‘SND, Symptomatic, DR pacemaker in-situ and intact AV conduction’.
Yes - Class IIa indication.
Yes / No
Should a device be implanted in this patient (list indication class)?
‘SND, Symptomatic, Frequent Vp is not expected or patient has significant co-morbidities that are likely to determine survival’.
Yes - Class IIa indication.
SR permanent pacing is reasonable for this patient.
Which class applies?
‘Reversible, transient causes of AVB such as lyme carditis should have medical therapy including temporary pacing if required before determination of a permanent pacing system’.
Class I indication.
Which class applies with respect to permanent PPM insertion?
‘Second or third degree AVB, chronically stable doses of necessary anti arrhythmic medication’.
Class IIa indication.
It is reasonable to proceed with a permanent system without observation of washout.
Which class applies with respect to device insertion?
‘Second or third degree AVB associated with cardiac sarcoidosis and survival >1yr’.
Class IIa indication.
Permanent PPM or ICD (if required).
Which class applies with respect to permanent PPM insertion?
‘Second or third degree AVB associated with thyroid abnormalities without myxedema’.
Class IIb indication.
Permanent pacing without further observation for reversibility may be considered.
Which class applies with respect to temporary transvenous pacing?
‘Symptomatic, Second or third degree AVB that is refractory to medical therapy’.
Class IIa indication.
Which class applies?
‘Opt for an externalised active fixation lead over a passive fixation temporary lead’.
For patients who require prolonged temporary pacing.
Class IIa indication.
Which class applies with respect to temporary transcutaneous pacing?
Second or third degree AVB with haemodynamic compromise refractory to antibradycardic medication’.
Class IIb indication.
Temporary transcutaneous pacing may be considered until a temporary transvenous or permanent pacemaker is placed.
Yes / No
Should a permanent pacing system be implanted in this patient (list class)?
‘1st degree AVB or Mobitz I or 2:1 block at the level of the AV node with symptoms that do not always correlated to the block’.
No - Class III indication.
