We examined the mitral valve motion, the mitral valve flow pattern, and changing atrioventricular (AV) delay in 34 patients with DDD pacemaker im-plantation, using M-mode echocardiography and pu-lse Doppler echocardiography.

In 28 patients, B-B' step and diastolic mitral regur-gitation (DMR) were induced by extending the AV delay. 8 of 12 patients who showed B-B'step and DMR with the AV delay≦165mS had heart failures. In such patients, P-B-B' step (DMR) interval was 174±31mS shorter than the other patients (216±26 mS, p<0.001), and Q-C interval was 131±26mS lon-ger than the other patients (63±31mS, p<0.001).

The minimal value of the AV delay that induces B-B'step and DMR can be decided under the influ-ence of cardiac functions, and this echocardiographic examination is useful, giving us information about the cardiac function of the patients with DDD-PM. B-B'step is the mitral valve motion that aorresponds with the DMR, so we can check the DMR through the B-B'step easily.
