The advent of biventricular devices has added new complexity to the evaluation of pacemaker function and follow-up. Consequently one must acknowledge the various circumstances that can disrupt ventricular resynchronization and provoke haemodynamic deterioration. In this paper we report upon haemodynamic deterioration following resynchronization therapy because of an erroneous connection of an epicardial right ventricular (RV) outflow tract lead to the left ventricular (LV) channel of the device. How ECG and echocardiography can guide the diagnosis and help in prematurely detecting abnormal pacing or loss of LV capture is discussed in detail below.
双心室装置的出现给起搏器功能评估和随访增加了新的复杂性。因此,必须认识到各种可能破坏心室再同步并导致血流动力学恶化的情况。在本文中,我们报告了因心外膜右心室(RV)流出道导线错误连接到装置的左心室(LV)通道而导致再同步治疗后血流动力学恶化的情况。下文将详细讨论心电图和超声心动图如何指导诊断并有助于早期发现异常起搏或左心室夺获丧失。
