Left ventricular noncompaction is associated with arrhythmias. The indication for implantation of devices for primary prophylaxis of sudden cardiac death in noncompaction is controversial, especially for patients without severe systolic dysfunction. The use of implantable loop-recorders to detect arrhythmias has not been reported so far.
A retrospective analysis of indications and results of implantation of loop-recorders in patients with left ventricular noncompaction.
Loop-recorders were implanted in 3 patients with noncompaction and moderately or preserved left ventricular systolic function. The recorders revealed pauses N3 s, leading to pacemaker implantation in one patient, and tachycardia leading to radiofrequency ablation in another patient. In the third patient, no arrhythmias have so far been detected.
From our limited experience we consider monitoring by a loop-recorder as a useful tool to detect arrhythmias in noncompaction-patients.
左心室心肌致密化不全与心律失常有关。在非致密化不全患者中植入设备以预防心源性猝死的适应证存在争议，特别是对于无严重收缩功能障碍的患者。目前尚未有报道使用植入式环路记录器来检测心律失常。
对左心室心肌致密化不全患者植入环路记录器的适应证和结果进行回顾性分析。
在 3 例左心室心肌致密化不全伴中度或保留的左心室收缩功能的患者中植入了环路记录器。记录器显示 N3s 暂停，导致 1 例患者植入起搏器，另 1 例患者发生心动过速并进行射频消融。在第 3 例患者中，目前尚未检测到心律失常。
根据我们的有限经验，我们认为环路记录器监测是检测非致密化不全患者心律失常的有用工具。
