The COVID-19 pandemic has triggered dramatic changes throughout everyday life — and in the medical community as well. Not only are providers across the country postponing elective procedures, but many are also encouraging people to avoid in-office appointments to reduce their risk of exposure to this highly contagious coronavirus.But what...
Radiofrequency ablation (RF Ablation or RFA) is a medical procedure in which part of the electrical conduction system of the heart, tumor or other dysfunctional tissue is ablated using the heat generated from medium frequency alternating current (in the range of 350–500 kHz). RFA is generally conducted in the outpatient setting, using either local anesthetics or conscious sedation anesthesia. When it is delivered via catheter, it is called radiofrequency catheter ablation....
Vagus Nerve Stimulation Vagus nerve stimulation (VNS) is a medical treatment that involves delivering electrical impulses to the vagus nerve. It is used as an add-on treatment for certain types of intractable epilepsy and treatment-resistant depression. Medical use VNS devices are used to treat drug-resistant epilepsy and treatment-resistant major depressive disorder (TR-MDD). Specifically, it is used for treatment-resistant focal...
Electroencephalography (EEG) Electroencephalography is an electrophysiological monitoring method to record electrical activity of the brain. It is typically noninvasive, with the electrodes placed along the scalp, although invasive electrodes are sometimes used, as in electrocorticography. EEG measures voltage fluctuations resulting from ionic current within the neurons of the brain. Clinically, EEG refers to the recording of the brain’s spontaneous electrical activity over a period...
Electromyography-(EMG) Electromyography (EMG) is an electrodiagnostic medicine technique for evaluating and recording the electrical activity produced by skeletal muscles. EMG is performed using an instrument called an electromyograph to produce a record called an electromyogram. An electromyograph detects the electric potential generated by muscle cells when these cells are electrically or neurologically activated. The signals can be analyzed to detect medical abnormalities, activation level,...
