a type of electrosurgery used to produce superficial desiccation of tissue.
fulgurationThe controlled surgical destruction of tissue by fulguration (using high-frequency electric current), in particular at margins of a malignancy.
A procedure where a high-energy laser beam is used to burn the cancerous tissue.

electrofulgurationtissue destruction produced by electrocautery (Table 1)
|ECG feature and duration||Comment|
|P wave =0.12 seconds||Depolarization of the atria|
|QRS complex =0.1 seconds||Depolarization of the ventricles|
|T wave||Ventricular repolarization|
|PR interval 0.12–0.22 seconds||The time, in seconds, from the start of the P wave to the start of the QRS complex, representing the time taken for the electrical activation (of the cardiac conduction system) to pass from the sinus node, through the atrium, the atrioventricular node and the His–Purkinje system to the ventricle|
Male: =0.44 seconds
Female: =0.46 seconds
|The time, in seconds, from the start of the QRS complex to the end of the T wave, representing the time taken for the depolarization and repolarization of the ventricular myocardium|
|ST segment||The period between the end of the QRS complex and the start of the T wave; in the normal heart, all myocardial cells are depolarized by this phase of the ECG|
a method of electrosurgery used to produce superficial desiccation of tissue, which employs a highly or moderately damped alternating electrical current that is radiated through a monoterminal active electrode that is held close to the patient so that sparks spray over the lesion being treated.
