1) Sinus node disease.
Pacing is indicated when symptoms can clearly be attributed to bradycardia.
2) Sinus node disease.
Pacing may be indicated when symptoms are likely to be due to bradycardia,
even if the evidence is not conclusive.
3) Sinus node disease.
Pacing is not indicated in patients with sinus bradycardia which is
asymptomatic or due to reversible causes.
4) Acquired AV block.
Pacing is indicated in patients with third- or second-degree type 2 AV block
irrespective of symptoms.
5) Acquired AV block.
Pacing should be considered in patients with second-degree type 1 AV block
which causes symptoms or is found to be located at intra- or infra-His levels
at EPS.
6) Acquired AV block.
Pacing is not indicated in patients with AV block which is due to reversible
causes.

Upgraded or de novo CRT in patients with
conventional pacemaker indications and HF
Recommendations
Class
Level
1) Upgrade from conventional PM or ICD is indicated in HF
patients with LVEF <35% and high percentage of ventricular pacing
who remain in NYHA class III and ambulatory IV despite adequate
medical treatment.
I
B
2) “De novo” implantation should be considered in HF patients,
reduced EF and expected high percentage of ventricular pacing in
order to decrease the risk of worsening HF.
IIa
B
Clinical perspectives
•
A strategy of initially conventional antibrady pacing with late upgrade in case of
worsening symptoms seems reasonable
•
In the decision process physicians should take into account the excess
complication rate related to the more complex biventricular system, the shorter
longevity of CRT devices and the excess of costs.

Choice of pacing mode
(and CRT optimization)

Recommendations
1) The goal of should be to achieve biventricular pacing as close to 100% as
possible since the survival benefit and reduction in hospitalization are strongly
associated with an increasing percentage of biventricular pacing.

2) Apical position of the LV lead should be avoided when possible.

3) LV lead placement may be targeted at the latest activated LV segment.

Clinical perspectives
• The usual (standard) modality of CRT pacing consists of simultaneous biventricular pacing
(RV and LV) with a fixed 100-120 ms AV delay with LV lead located in a posterolateral
vein, if possible.

Clinical perspectives
• LV pacing alone… seems to be non-inferior to biventricular pacing for improving soft end-points (quality
of life, exercise capacity and LV reverse remodelling) …. LV pacing alone seems particularly appealing
in children and young adults.

• Program an asynchronous mode in
PM-dependent and an inhibited mode in
non PM-dependent patients.
• In contrast, use an inhibited pacing mode
for patients without PM dependence, to
avoid inappropriate pacing due to tracking
of electromagnetic interference.
• Automatically performed by an external

• Deactivate other pacing functions.
• Deactivate tachyarrhythmia monitoring and
therapies (ATP/shock).
• Reprogram device immediately after the
