Indications for pacing

Indications for cardiac resynchronization therapy (CRT)

Indications for intra-cardiac defibrillator (ICD) therapy

Classifications of Bradyarrhythmias

There are two types of bradyarrhythmias

Sinus node

AV node

Sinus node dysfunction

Sinus Arrest

Sinus Bradycardia

Sinus node dysfunction

Chronotropic Incompetence

Tachybrady syndrome

AV node dysfunction

First Degree AV block

Second Degree AV block

Mobitz Type 1 – Wenckebach

Mobitz Type 2

Third Degree AV block – Complete heart

block

Bifasicular/Trifasicular block

First-Degree AV Block

PR interval > 200 ms

Delayed conduction through the AV Node

Second-Degree AV Block –

Mobitz I (Wenckebach block)

Progressive prolongation of the PR interval until there is failure to conduct and a ventricular beat is dropped

Second-Degree AV Block –

Mobitz II

Regularly dropped ventricular beats 2:1 block (2 P-waves for every 1 QRS complex)

Third-Degree AV Block Complete Heart Block

No impulse conduction from the atria to the ventricles

Fascicular Block

Right bundle branch block and left anterior hemiblock

Right bundle branch block and left posterior hemiblock

Complete left bundle branch block

Classifications of Bradyarrhythmias

There are two types of bradyarrhythmias

Sinus node

AV node

Indications for Pacing in Persistent Bradycardia

Indication for Pacing in Intermittent Documented Bradycardia

BBB and Unexplained Syncope

CSM: carotid sinus massage;

ILR =implantable loop recorder.

Indication for Pacing in BBB

Indication for Pacing in Undocumented Reflex Syncpe

Indication in Unexplained Syncope

Common Pacing Indications

Sinus Node Disease (SND), or Sick Sinus

Syndrome

High degree AV Block (Mobitz II & 3rd AVB)

Chronotropic Incompetence

Class I Recommendations

Level of Evidence: A

With LVEF ≤ 35% due to prior MI who are at least 40 days post-MI and are in NYHA Functional Class II or III

With LV dysfunction due to prior MI who are at least 40 days post-MI, have an LVEF ≤ 30%, and are in NYHA Functional Class I

Who are survivors of cardiac arrest due to VF or hemodynamically unstable sustained VT after evaluation to define the cause of the event and to exclude any completely reversible causes

Class I Recommendations

Level of Evidence: B

With nonischemic DCM who have an LVEF ≤ 35% and who are in NYHA Functional Class II or III

With nonsustained VT due to prior MI, LVEF < 40%, and inducible VF or sustained VT at electrophysiological study

With structural heart disease and spontaneous sustained VT, whether hemodynamically stable or unstable

With syncope of undetermined origin with clinically relevant, hemodynamically significant sustained VT or VF induced at electrophysiological study

Class IIa Recommendations

Level of Evidence: B

To reduce SCD in patients with Long QT Syndrome who are experiencing syncope and/or VT while receiving beta blockers

Class IIa Recommendations Level of Evidence: C

With unexplained syncope, significant LV dysfunction, and nonischemic DCM

With sustained VT and normal or near-normal ventricular function

With catecholaminergic polymorphic VT who have syncope and/or documented sustained VT while receiving beta blockers

For the prevention of SCD in patients with ARVD/C who have one or more risk factors for SCD

With HCM who have one or more major risk factors for SCD

With Brugada syndrome who have had syncope or documented VT that has not resulted in cardiac arrest

With cardiac sarcoidosis, giant cell myocarditis, or Chagas disease

For nonhospitalized patients awaiting transplantation
