Key result
A double pulse scheme where a test pulse precedes the regular output pulse allows for re-balancing of the electrode tissue interface, enabling reliable detection of evoked P- or R waves.

Does a double pulse scheme and individual lead optimization improve atrial and ventricular capture detection in cardiac pacing?
A novel double pulse scheme and individual lead optimization can improve the detection of evoked P- and R-waves by mitigating polarization artifacts in cardiac pacing.
Vonk et al. (1998) studied this question. Double pulse scheme for capture detection was evaluated on Evoked P- or R wave detection. A double pulse scheme where a test pulse precedes the regular output pulse allows for re-balancing of the electrode tissue interface, enabling reliable detection of evoked P- or R waves.
