Metrazol shock is a medical treatment that was once commonly used to treat mental illnesses. However, due to its potentially dangerous side effects, it is no longer widely used today. There are several synonyms for Metrazol shock, including cardiazol shock, convulsion therapy, and electroshock therapy. These treatments all involve inducing seizures in the patient as a way to treat mental illness. While electroshock therapy is still used in some cases, it has been heavily criticized for its potential harm. As a result, many doctors and mental health professionals have turned to more modern and less invasive treatments to help patients who suffer from mental illness.
