Facilitation of DDD follow-up using the DDT mode.
To facilitate follow-up, modern dual chamber pacemakers provide a variety of diagnostic features like ECG interpretation channels and intracardiac electrograms. For evaluation of the sensing performance at rest and during exercise, for assessment of the presence of crosstalk, and for measurement of the retrograde conduction time, dual chamber triggered pacing, particularly the DDT mode, can be used alternatively or additionally in pacemakers equipped with this option. In contrast to ECG interpretation channels, ECG documentation is not required for evaluation of the sensing performance, because the triggered pulses serving as markers for sense events can also be seen on the monitor. Selection of the DDT mode not only as temporary but also as permanent program serves to facilitate pacemaker ECG interpretation for exercise tests and Holter recordings as well.
