Electrocoagulation is a procedure that uses an electric current to coagulate blood and destroy tissue, commonly used in medical and industrial applications. Some synonyms for electrocoagulation include electrosurgery, electrocautery, electrothermolysis, and radiofrequency ablation. Electrosurgery uses an electric current to cut through tissue, while electrocautery uses heat to coagulate and destroy tissue. Electrothermolysis is the use of a high-frequency electric current to kill cells. Radiofrequency ablation uses a special needle that delivers a high-frequency electric current to destroy tumors and other abnormal tissues. Regardless of the name, all of these procedures use electricity to modify or destroy tissue.
