Summary

This study looked at 80 adults aged 45-85 having knee replacement under spinal anesthesia. Researchers checked their ECG before and after surgery to see if the anesthesia changed the heart's electrical axis. The goal was simply to observe and measure any changes, not to treat or cure any condition.
