electrofulguration

 [e-lek″tro-ful″gur-ra´shun]
a type of electrosurgery used to produce superficial desiccation of tissue.

fulguration

The controlled surgical destruction of tissue by fulguration (using high-frequency electric current), in particular at margins of a malignancy.

Electrofulguration

A procedure where a high-energy laser beam is used to burn the cancerous tissue.
Mentioned in: Bladder Cancer

electrofulguration

tissue destruction produced by electrocautery (Table 1)
Table 1: Features of the normal electrocardiogram (ECG) waveform
ECG feature and durationComment
P wave ≤0.12 secondsDepolarization of the atria
QRS complex ≤0.1 secondsDepolarization of the ventricles
T waveVentricular repolarization
PR interval 0.12-0.22 secondsThe 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
QT interval
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 segmentThe 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

electrofulguration

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.
