Neurostimulator-induced ECG artefacts: A systematic analysis

Electrodiagnostic artifacts due to neurostimulation devices for drug resistant epilepsy

“…Our study of DRE patients, a patient group that requires frequent electro-diagnostic tests, as well as the intermittent nature of neurostimulation therapies for DRE, stresses out even more the importance of acknowledging these episodic transients as artifacts. Furthermore, the common use of monopolar stimulation for epilepsy rather than bipolar stimulation in DBS for movement disorders increase the chance for eliciting artifacts in the ECG [7] , [8] , [15] , [26] .…”

“…These artifacts are influenced by the polarity of electric impulses and stimulation parameters including pulse amplitude and width, and in the case of ECG, proximity, or orientation of electrical source relative to ECG leads [6] . There are reports of EEG and ECG artifacts originating from patients with movement disorders treated with DBS [7] , [8] , however, there are only a few reports regarding the various neurostimulations artifacts in epilepsy patients [4] , [9] , [10] , [11] , [12] , [13] , [14] , [15] .…”

Radiofrequency atrial flutter and atrial fibrillation ablation in a patient with deep brain stimulation

“…Deep brain stimulation (DBS) is an advanced treatment for PD's motor symptoms and several other neurological conditions 2,3 . It is known to induce significant ECG artifacts 4,5 . There is a concern for brain damage due to local heating in proximity to the DBS electrode while using diathermy although experimental data with monopolar electrosurgery has actually shown minor temperature elevations and no tissue damage 6–8 …”

“…2,3 It is known to induce significant ECG artifacts. 4,5 There is a concern for brain damage due to local heating in proximity to the DBS electrode while using diathermy although experimental data with monopolar electrosurgery has actually shown minor temperature elevations and no tissue damage. [6][7][8] Supraventricular tachycardia ablation has been successfully performed in PD patients with DBS, and atrioventricular nodal reentrant tachycardia ablation has been performed with radiofrequency ablation, cryoablation and 3D impedance-based electroanatomic mapping (EAM) system.…”
