The S1Q3T3 electrocardiographic (ECG) pattern is commonly described in patients with acute pulmonary embolism (PE). However, it is a nonspecific, nonsensitive ECG finding associated with right heart strain that can be found in other acute presentations as well. Most of these acute diseases are of cardiac or pulmonary origin and pathophysiology. Acute abdominal pathologies are not well-known etiologies for this characteristic ECG pattern. We present a case of postoperative colonic dilation and ileus that showed up as acute, new atrial fibrillation (AF) associated with the S1Q3T3 pattern and that resolved after the resolution of the ileus symptoms.
S1Q3T3心电图模式常见于急性肺栓塞（PE）患者。然而，它是一种与右心劳损相关的非特异性、非敏感性心电图表现，也可见于其他急性病症。这些急性疾病大多源于心脏或肺部的病因及病理生理过程。急性腹部病变并非这种特征性心电图模式的常见病因。我们报告一例术后结肠扩张和肠梗阻病例，该病例表现为与S1Q3T3模式相关的急性新发房颤，肠梗阻症状缓解后房颤也随之消失。
