PY - 2016 T2 - Anesthesiology Core Review: Part Two Advanced Exam AB - A cardiac pacemaker (PM) is an electronic device that provides electrical stimuli for myocardial contraction when indicated. Current PM devices are used to treat bradyarrhythmias, tachyarrhythmias, and resynchronization, and, in some cases, are combined with implantable defibrillators. The first permanent cardiac PM was implanted in a human in 1958. Technological advances have since revolutionized the function of the PM and expanded therapeutic indications. The device has evolved from simple, single-chamber, fixed-rate PMs to multichamber, rate-responsive units with the capability of pacing, cardioversion, and defibrillation.
