Indications for Pacemaker (Class I and IIa/b Recommendations) Sinus node dysfunction (SND) with symptomatic bradycardia Symptomatic chronotropic incompetence Required drug therapy causing symptomatic bradycardia SND with HR < 40 bpm; bradycardia and symptom connection unclear Unexplained syncope and EP study (+) for SND Conisder for minimal symptoms but HR < 40 bpm while awake Type II second-degree AV block, or complete third-degree AV block with: Bradycardia + symptoms Arrhythmias + required bradycardic meds Asymptomatic awake with pauses > 3 sec, Asymptomatic awake with v-rate < 40 bpm, Asymptomatic awake with infra-His conduction Asymptomatic awake with AF and > 5 sec pauses After catheter ablation of AV junction Post-operative AVB not expected to resolve Neuromuscular: myotonic dystrophy, Kearns-Sayre, Erb dystrophy, peroneal muscular atrophy Symptomatic bradycardia + second-degree AVB Asymptomatic bradycardia + type II second-degree AVB (narrow or wide QRS) Asymptomatic second-degree AVB at intra or infra His level on EP study Asymptomatic complete third-degree AVB with: V-rate < 40 bpm LV dysfunction Site of block below AV node Reasonable in V-rate > 40 and persistent First or Second Degree AVB with: Pacemaker syndrome Hemodynamic compromise Muscular dystrophy of any AV block, with or without symptoms Recurrence of AVB is expected after offending drug is withdrawn Advanced second-degree AVB or third-degree AVB Type II 2nd degree AVB Alternating Bundle Branch Block Syncope of unknown type after exclusion of other causes including VT HV > 100 msec, even if asymptomatic EP study with infra-Hisian block, even if non-physiological After STEMI with: persistent 2nd/3rd DAVB regardless of symptoms, transient infranodal AVB Carotid sensitivity causing syncope and ventricular asystole > 3 sec Hypersensitive cardioinhibition >...
