System providing ventricular pacing and biventricular coordination

(57) A summary heart rhythmic-movement managerial system includes the technology for calculating a directions pacing interval, AV delay, or other timing intervals. In a certain embodiment, at least one copy of variable directions pacing interval is calculated based on basic endogenous cardiac beats. Even if ventricular cardiac beats are irregularity (atrial fibrillation exists), a directions pacing interval is used and time to offer both the 室協調 treatment is adjusted. In the another embodiment, at least one copy of variable filter directions AV interval is calculated based on a basic endogenous AV interval. When atrial cardiac beats are not irregular, a directions AV interval is used and time to offer an atrium flattery 性両室 cooperation treatment is adjusted. You may determine other directions timing intervals similarly. A directions pacing interval, AV delay, or other timing intervals can be used in combination with a sensor directions speed index.
