Why the study?
What are the sequential electrocardiographic and hemodynamic changes during intraoperative coronary angiospasm?
What are the sequential electrocardiographic and hemodynamic changes during intraoperative coronary angiospasm?
Intraoperative coronary angiospasm initially presents with bradycardia and hypotension before ST-segment elevation, highlighting the importance of continuous hemodynamic and multi-lead ECG monitoring.
Bradycardia and hypotension may precede ST changes in intraoperative coronary spasm; this case report leaves open prospective validation of monitoring.
