Can pace and sense in one, two, or three chambers.
Two types of lead: unipolar or bipolar.
International codes: first letter, chamber paced (V = ventricle, A = atrium, D = dual); second letter, chamber sensed (V = ventricle, A = atrium, D = dual); third letter, how the device responds to the event (I = inhibits, T = triggers, D = dual, O = nothing). A fourth letter can be present to describe added features.
Ventricular lead placed most commonly in RV apex, RVOT, or on septum.
Atrial lead placed in the right atrial appendage.
Indications: (1) symptomatic complete heart block; (2) symptomatic second-degree heart block; (3) bifascicular block with intermittent third-degree block, second-degree block, or BBB; (4) trifascicular block with intermittent third-degree or second-degree block; (5) symptomatic sinus node dysfunction; (6) symptomatic chronotropic incompetence; (7) carotid sinus hypersensitivity; (8) sustained VT caused by pauses; (9) drugs that result in symptomatic...
