Key result
SIQIIITIII pattern on ECG flags acute cor pulmonale and aids intraoperative PE diagnosis.
Why the study?
Electrocardiogram alone is thought to have limited utility in suspected pulmonary embolism due to low sensitivity and specificity, necessitating further evaluation of its role in intraoperative PE detection.
Case Report (n=1)
Despite generally limited sensitivity and specificity, ECG can play an invaluable role in the early detection of intraoperative pulmonary embolism.
SIQIIITIII may prompt CTA in select unstable perioperative patients; hypothesis-generating for ECG utility in PE diagnosis.
Pulmonary embolism (PE) is an important cause of perioperative morbidity and mortality. In patients with suspected PE, electrocardiogram (ECG) alone is thought to have a limited utility due to its low sensitivity and specificity. This case report describes a patient with intraoperative PE presenting with hypotension and hypoxemia for whom the ECG finding of SIQIIITIII was key in identifying acute cor pulmonale. The ECG was paramount in our decision to acquire computed tomography angiography to confirm the diagnosis, reinforcing its invaluable role in early detection of intraoperative PE.

Pleticha et al. (2017) conducted a case report in Intraoperative Pulmonary Embolism (n=1). Electrocardiogram (ECG) was evaluated on Identification of acute cor pulmonale and early detection of intraoperative PE. The ECG finding of SIQIIITIII was key in identifying acute cor pulmonale and prompting computed tomography angiography to confirm intraoperative pulmonary embolism.
