Overview
Pacemaker insertion is a surgical procedure performed under local anesthesia in an electrophysiologic laboratory. Temporary transcutaneous or transvenous pacemaker insertion is the treatment of choice for all AV blocks.
Surgery
- Before insertion of a pacemaker, all reversible causes of an AV block, like medications and electrolyte imbalances should be treated. Other causes of reversible AV block include Lyme disease, vagal reaction, hypothermia and recent cardiac surgery causing injury to the AV node.
- Methods of cardiac pacing include:
- Ventricular pacing
- Dual chamber pacing
- Temporary cardiac pacing
- Permanent cardiac pacing
Complications
Complications of a pacemaker include:
- Pneumothorax
- Hemothorax
- Cardiac tamponade
- Infections, although rare.
Lifestyle Modifications
- Avoid contact sports.
- Restricted weight lifting for the first 4 to 6 weeks.
- Avoid electromagnetic fields from powerful electric lines which may interfere with the functioning of the pacemaker and slow it down.
Follow-up
- Follow-up with a cardiologist is indicated to look for development of complications of pacemaker insertion and also in case of unexplained syncope suggesting progression of the heart block.
2012 ACC/AHA/HRS Guidelines for Device-Based Therapy of Cardiac Rhythm Abnormalities (DO NOT EDIT)[1][2]
Acquired Atrioventricular Block in Adults (DO NOT EDIT)[2]
Class I |
"1. Permanent pacemaker implantation is indicated for third-degree and advanced second-degree AV block at any anatomic level associated with bradycardia with symptoms (including heart failure) or ventricular arrhythmias presumed to be due to AV block. (Level of Evidence: C)[3][4][5][6]" |
”2. Permanent pacemaker implantation is indicated for third-degree and advanced second-degree AV block at any anatomic level associated with arrhythmias and other medical conditions that require drug therapy that results in symptomatic bradycardia. (Level of Evidence: C)[3][4][5][6]" |
"3. Permanent pacemaker implantation is indicated for third-degree and advanced second-degree AV block at any anatomic level in awake, symptom-free patients in sinus rhythm, with documented periods of asystole greater than or equal to 3.0 seconds[7]) or any escape rate less than 40 bpm, or with an escape rhythm that is below the AV node. (Level of Evidence: C)[8][9]" |
"4. Permanent pacemaker implantation is indicated for third-degree and advanced second-degree AV block at any anatomic level in awake, symptom-free patients with atrial fibrillation and bradycardia with 1 or more pauses of at least 5 seconds or longer. (Level of Evidence: C)" |
"5. Permanent pacemaker implantation is indicated for third-degree and advanced second-degree AV block at any anatomic level after catheter ablation of the AV junction. (Level of Evidence: C)[10][11]" |
"6. Permanent pacemaker implantation is indicated for third-degree and advanced second-degree AV block at any anatomic level associated with postoperative AV block that is not expected to resolve after cardiac surgery. (Level of Evidence: C)[6][12][13][14]" |
"7. Permanent pacemaker implantation is indicated for third-degree and advanced second-degree AV block at any anatomic level associated with neuromuscular diseases with AV block, such as myotonic muscular dystrophy, Kearns-Sayre syndrome, Erb dystrophy (limb-girdle muscular dystrophy), and peroneal muscular atrophy, with or without symptoms. (Level of Evidence: B)[15][16][17][18][19][20][21]" |
"8. Permanent pacemaker implantation is indicated for second-degree AV block with associated symptomatic bradycardia regardless of type or site of block. (Level of Evidence: B)[22]" |
"9. Permanent pacemaker implantation is indicated for asymptomatic persistent third-degree AV block at any anatomic site with average awake ventricular rates of 40 bpm or faster if cardiomegaly or left ventricular (LV) dysfunction is present or if the site of block is below the AV node. (Level of Evidence: B)[5][23]" |
"10. Permanent pacemaker implantation is indicated for second- or third-degree AV block during exercise in the absence of myocardial ischemia. (Level of Evidence: C)[24]" |
Class III (No Benefit) |
"1. Permanent pacemaker implantation is not indicated for asymptomatic first-degree AV block. (Level of Evidence: B)[25]" |
”2. Permanent pacemaker implantation is not indicated for asymptomatic type I second-degree AV block at the supra-His (AV node) level or that which is not known to be intra- or infra-Hisian. (Level of Evidence: C)[22]" |
”3. Permanent pacemaker implantation is not indicated for AV block that is expected to resolve and is unlikely to recur[26] (e.g., drug toxicity, Lyme disease, or transient increases in vagal tone, or during hypoxia in sleep apnea syndrome in the absence of symptoms). (Level of Evidence: B)[27][26]" |
Class IIa |
"1. Permanent pacemaker implantation is reasonable for persistent third-degree AV block with an escape rate greater than 40 bpm in asymptomatic adult patients without cardiomegaly. (Level of Evidence: C)[3][4][5][6][28]" |
”2. Permanent pacemaker implantation is reasonable for asymptomatic second-degree AV block at intra- or infra- His levels found at electrophysiological study. (Level of Evidence: B)[5][22][23]" |
”3. Permanent pacemaker implantation is reasonable for first- or second-degree AV block with symptoms similar to those of pacemaker syndrome or hemodynamic compromise. (Level of Evidence: B)[29][30]" |
”4. Permanent pacemaker implantation is reasonable for asymptomatic type II second-degree AV block with a narrow QRS. When type II second-degree AV block occurs with a wide QRS, including isolated right bundle-branch block, pacing becomes a Class I recommendation. (Level of Evidence: B)[5][6][29][31]" |
Class IIb |
"1. Permanent pacemaker implantation may be considered for neuromuscular diseases such as myotonic muscular dystrophy, Erb dystrophy (limb-girdle muscular dystrophy), and peroneal muscular atrophy with any degree of AV block (including first-degree AV block), with or without symptoms, because there may be unpredictable progression of AV conduction disease. (Level of Evidence: B)[15][16][17][18][19][20][21]" |
”2. Permanent pacemaker implantation may be considered for AV block in the setting of drug use and/or drug toxicity when the block is expected to recur even after the drug is withdrawn. (Level of Evidence: B)[32][27]" |
