After implanting a CRT device, consistent and scheduled patient follow-up is mandatory. Besides determining electrode parameters and reviewing arrhythmic episodes, these follow-ups focus on monitoring and optimizing congestive heart failure therapy. Therefore new CRT devices present methods for heart failure surveillance and telemetric transmission of the acquired data, which allows the physician to respond immediately to the varying needs of the respective heart failure patient. In addition to cardiac resynchronization, optimization of atrioventricular (AV) and interventricular (VV) delay provide major hemodynamic benefits. As echocardiographic optimization of AV and VV delay is time consuming it is often not feasible during daily clinical practice. Therefore implemented algorithms that automatically determine and adapt AV and VV delays with respect to the fluctuating needs of the patients are essential. This article presents the current state of monitoring and optimization methods in CRT devices.
植入心脏再同步治疗（CRT）设备后，对患者进行持续且定期的随访是必不可少的。除了确定电极参数和回顾心律失常事件外，这些随访还着重于监测和优化充血性心力衰竭治疗。因此，新型CRT设备具备心力衰竭监测方法以及所采集数据的遥测传输功能，这使得医生能够立即对各个心力衰竭患者的不同需求做出反应。除心脏再同步外，优化房室（AV）和心室间（VV）延迟可带来显著的血流动力学益处。由于通过超声心动图优化AV和VV延迟耗时较长，在日常临床实践中往往不可行。因此，实施能够根据患者不断变化的需求自动确定并调整AV和VV延迟的算法至关重要。本文介绍了CRT设备中监测和优化方法的当前状况。
