I. Introduction
The focus of these gudelnes s the approprate
use of heart rhythm devces (pacemakers for
bradyarrhythmas and heart falure management,
e.g., cardac resynchronzaton, and mplantable
cardoverter-defbrllators [ICDs]), not the treatment
of cardac arrhythmas. The fact that the use of a
devce for treatment of a partcular condton s
lsted as a Class I ndcaton (benefcal, useful,
and effectve) does not preclude the use of other
therapeutc modaltes that may be equally effec-
tve. As wth all clncal practce gudelnes, the
recommendatons n ths document focus on
treatment of an average patent wth a specfc

dsorder and may be modfed by patent comor-
bdtes, lmtaton of lfe expectancy because of
coexstng dseases, and other stuatons that
only the prmary treatng physcan may evaluate
approprately.
The recommendatons lsted n ths document are,
whenever possble, evdence based. The schema
for classfcaton of recommendatons and level
of evdence s summarzed n Table 1, whch also
llustrates how the gradng system provdes an
estmate of the sze of the treatment effect and an
estmate of the certanty of the treatment effect.
The followng represents a subset of recommenda-
tons for the mplantaton of antarrhythma devces.
We chose to provde only recommendatons n the
pocket gude and recommend readers access the
full-text and executve summary documents for
more explanaton. Table 2 and Figures 1 and 2 are
provded to help practtoners choose whch pacng
devce s approprate for an ndvdual patent.
