Implanted Cardioverter/Defibrillators

A similar code, known as the NASPE/BPEG Defibrillator Code or NBD Code,10 exists for implanted cardioverter/defibrillators (ICDs), as defined in Table 2.

Table 2. Defibrillator Codea

Position I (Shock Chamber)

Position II (Antitachycardia Pacing Chamber)

Position III (Tachycardia Detection)

Position IV (Antibradycardia Pacing Chamber)

O = none

O = none

E = electrocardiogram

O = none

A = atrium

A = atrium

H = hemodynamic

A = atrium

V = ventricle

V = ventricle

V = ventricle

D = dual (A + V)

D = dual (A + V)

D = dual (A + V)

Examples are as follows:

DDH defibrillator

VOEO defibrillator

There is also a Short Form of the NBD Code intended only for use in conversation:

ICD-B: ICD with antibradycardia pacing as well as shock

ICD-T: ICD with antitachycardia pacing as well as shock and antibradycardia pacing

ICD-S: ICD with shock capability only

The foregoing terms can each represent a variety of devices; for instance, ICD-S could indicate VO, VOE, VOEO, DOH, or DOHV. The same devices may also be represented by more than 1 term, eg, ICD-B may also represent VO and VOE, among other devices. Therefore, only the Long Form is used in writing. As in the case of the NBG Code, at first mention of an ICD it is good practice to include a prose description as well as the NBD Code designation.

For maximum conciseness and completeness in ICD labeling and record keeping, the first 3 positions of the NBD Code are given, followed after a hyphen by the first 4 positions of the NBG Code. Thus, “VAE-DDDR” refers to an ICD providing ventricular shock, atrial antitachycardia pacing, EGM sensing for tachycardia detection, and dual-chamber, adaptive-rate antibradycardia pacing.
