Recommendations for permanent pacemaker implantation for bradycardia associated atrioventricular block
| Recommendations for permanent pacemaker implantation for bradycardia associated atrioventricular block |
| (Class IIa, Level of Evidence B): |
|
❑ In patients with Lamin A/C mutation such as limb girdle, emery dreifuss, muscular dystrophies, in the presence of prolonged PR interval>240 ms and LBBB
,permanent pacing with additional defibrillator therapy is recommended while life expectancy>1 year |
| (Class IIa, Level of Evidence C): |
|
❑Permanent pacing is recommended in patients with symptomatic profound First-degree AV block when symptoms clearly related to atrioventricular block |
| (Class IIb, Level of Evidence C): |
|
❑ In patients with neuromuscular disease such as myotonic dystrophy type 1 in the presence of prolonged PR interval>240 ms and QRS duration >120 ms or fascicular block, permanent pacing with additional defibrillator therapy is reasonable if life expectancy>1 year |
Contraindications of permanent pacemaker implantation for bradycardia associated atrioventricular block
| Contraindications of permanent pacemaker implantation for bradycardia associated atrioventricular block |
| (Class III (Harm), Level of Evidence C): |
|
❑ Permanent pacing is not recommended in patients with First-degree atrioventricular block or mobitz type 1 second degree atrioventricular block (wenchebache), or 2:1 atrioventricular block when the level of block is in atrioventricular node or symptoms are not related to atrioventricular block |
- Common factors associated placement of permanent pacemaker include:
- Presence or absence of symptoms
- Level of atrioventricular block
- Unstable scaped ventricular rhythm with rapid progression to complete heart block
- First-degree AV block is typically a benign condition that do not progress suddenly to complete heart block.
- Placement of permanent pacemaker is reserved for the condition that symptomatic First-degree AV block affects quality of life.
