Sumario: | This case report presents the clinical course of a 70-year-old female with a history of hypertension who developed sinus pauses following abdominal surgery, ultimately requiring the placement of a pacemaker. The patient initially presented with altered mental status preceded by abdominal pain, which progressed to confusion and obtundation. Examination revealed signs of toxicity, tachycardia, tachypnea, and a distended abdomen with absent bowel sounds. A computed tomography (CT) scan of the abdomen indicated closed-loop small bowel obstruction with free air and ascites. The patient underwent exploratory laparotomy, revealing purulent fluid and a necrotic, perforated appendix, leading to appendectomy and peritoneal irrigation. Subsequent surgeries addressed the coagulative necrosis of the omentum and wound closure. During the recovery period, the patient exhibited bradycardia with sinus pauses, including episodes of complete heart block. Cardiology consultation attributed this to increased parasympathetic tone following surgery and recommended the placement of a temporary transvenous pacemaker. As the patient's condition improved, the sinus pacing function progressively returned, leading to the removal of the pacemaker. This case underscores the potential development of sinus pauses after abdominal surgery and highlights the importance of prompt recognition, appropriate management, and collaboration between surgical and cardiology teams to ensure patient recovery. |
