    • An implantable cardiac device is programmed to promote intrinsic rhythm of a patient's heart to alleviate orthostatic hypotension. In one implementation, the cardiac device is set in a reduced rate mode while the patient is in a less upright position, such as when resting in a supine position. If the patient is in intrinsic rhythm when transitioning to a more upright position, the cardiac device disables administration of any increased pacing rate for a programmed duration. In this manner, the patient will experience a more natural variation in heart rate during transition from the less upright posture to the more upright posture (e.g., from supine to sitting or standing). On the other hand, if the patient is being paced during the transition, the cardiac device administers an increased base rate or triggers an orthostatic response algorithm.
    • 可植入心脏装置被编程以促进患者心脏的内在节律以减轻直立性低血压。 在一个实施方案中,当患者处于较不直立的位置时,例如在仰卧位置休息时,将心脏装置设置为降低速率模式。 如果患者在过渡到更直立的位置时处于内在节律,则心脏设备会禁止在编程持续时间内施加任何增加的起搏速率。 以这种方式,患者将在从较不直立的姿势到更直立的姿势(例如,从仰卧到坐或站立)的过渡期间经历更加自然的心率变化。 另一方面,如果在转换期间患者正在起搏,则心脏装置管理增加的基本速率或触发立体响应算法。
