Pectus excavatum is the most common chest wall deformity, and some patients also have it combined with cardiac arrhythmias. It is a rare occurrence for there to be a severe conduction block that requires a temporary pacemaker implantation before the surgical correction. Here we reported a case of pectus excavatum with a second-degree atrial-ventricular (AV) block (Mobitz II) who had temporary pacemaker implantation before the Nuss procedure. The young patient had a chest wall deformity for 6 years and it got worse with age. The Haller index was 4.21, and we evaluated that he should receive the Nuss procedure. An AV block was found during the preoperative electrocardiogram examination; furthermore, Holter monitor proved that he had first-degree AV block and a second-degree AV block (Mobitz II). After consultation with the anesthesiologist and cardiologist, we suggested that a temporary pacemaker placement should be performed under local anesthesia before the minimally invasive operation and removed as soon as the patient revived from general anesthesia. A postoperative Holter monitor was implemented, and the conduction defect disappeared shortly after the operation. However, the Holter monitor showed that the conduction defect was still existed during the follow-up period, which indicated that severe conduction defects should be originated from the conduction system itself, rather than the compression to the heart. The temporary pacemaker was essential to ensure the conducting of the operation went smoothly.
