title: [Clinical investigation of arrhythmia appearing after resection for lung cancer].
abstract: BACKGROUND
  Arrhythmia, especially atrial fibrillation (AF) is a common complication during the early postoperative period of thoracic surgery.
  
  
  OBJECTIVE
  To (1) characterize arrhythmia appearing after lung cancer resection, (2) evaluate risk factors for postoperative arrhythmia.
  
  
  RESULTS
  We retrospectively studied 131 patients who underwent primary lung cancer resection in our hospital between January 2005 and December 2006. The average age at diagnosis was 68 +/- 9 yr. Arrythmia occurred in 16 patients (11.3%) (12 AF, 1 PSVT, 2 PAC, 1 sinus bradycardia). Arrhythmia occurred at postoperative day 2.3 +/- 1.7 (mean, range 0 to 6), and improved in all cases within 3 days of onset either by treatment with antiarrhythmic agents or spontaneously.
  
  
  CONCLUSIONS
  AF was the most common arrhythmia (12/16 patients, 75%) among the complications associated with lung cancer resection. It was assumed that postoperative AF would be transient and improved by optimal management. Our data suggest that age (> or = 70-years-old) and operation time (> or = 300 min) were regarded as risk factors for postoperative arrhythmia.
