Pacemaker
nomenclature
   
In 1987 the North American Society
of Pacing and Electrophysiology (NASPE) and the British Pacing and
Electrophysiology Group (BPEG) set up the NBG (NASPE/BPEG Generic) code to
describe different pacing modes. To incorporate new technologies such as
dual-chamber pacing, this code was updated in 2002.
   
  The first letter of the code
signifies the chamber being paced:

O = none

A = atrium

V = ventricle

D = dual (A + V)

(Manufacturers' designation only: S = single [A or V])
   
  The second letter signifies the
chamber being sensed:

O = none

A = atrium

V = ventricle

D = dual (A + V)

(Manufacturers' designation only: S = single [A or V])
   
  The third letter signifies the
response to sensing:

O = none

I = inhibited

T = triggered

D = dual (T + I)
   
  The fourth letter signifies rate
modulation:

O = none

R = rate modulation
   
  The fifth letter signifies
multisite pacing:

O = none

A = atrium

V = ventricle

D = dual (A + V)
   
For example, 'DDD' indicates
dual-chamber pacing with no rate modulation or multisite pacing. 'AAI'
indicates atrial pacing inhibited by sensed spontaneous atrial
depolarisations; no rate modulation or multisite pacing.
