A 38-year-old woman underwent a laparoscopic combined hysteroscopic tubal lavage under general anesthesia. This is a common gynecologic procedure. During the surgery, her heart rate dropped to 40 beats per minute. Her electrical signals in the heart, measured as the QTc interval, began to stretch. The maximum stretch reached 581 milliseconds before returning to a normal 421 milliseconds one month later.
The patient experienced a cardiac arrest due to a specific type of dangerous heart rhythm called torsade de pointes. This condition is known as acquired long QT syndrome. It means the heart's electrical recovery time got too long, causing the rhythm to become unstable. The surgery setting involved general anesthesia and the specific laparoscopic technique.
Doctors managed the situation with timely resuscitation and correction of the factors causing the issue. The patient survived and her heart signals normalized within a month. This case highlights that even common surgeries can trigger rare heart problems in susceptible individuals. Early recognition of abnormal heart signals is vital for improving outcomes.
