“…Appropriate grounding of machines to prevent charge accumulation should be tested. Various electrical systems should be checked for compatibility before using them together 17. In the near future, we might have sophisticated monitors without the problem of ECG interference; until then, artefacts should also be taken into consideration and ruled out before managing arrhythmias.…”

ECG artefacts are defined as abnormalities in the monitored ECG, which result from measurement of cardiac potentials on the body surface and are not related to the electrical activity of the heart. In the operation theatre, the use of various types of electrical equipment may interfere with ECG interpretation. We describe our experience with artefacts resembling atrial fibrillation when a nerve integrity monitoring device was used on a patient undergoing posterior fossa surgery for epidermoid tumour. These artefacts resemble serious arrhythmias and may result in unwanted interventions. To enable better identification of such artefacts, a 12-lead ECG should be considered as it will display rhythm in all the leads; while artefacts will present in only a few leads, true arrhythmia will be present in all the 12 leads. Our case report aims to increase awareness regarding ECG artefacts and to explain how to distinguish them from actual arrhythmias.

“…Sakiewicz et al reported an abnormal ECG artifact from concomitant use of hemodialysis machine and IABP. [5] Literature evidence speaks about many possible reasons behind an ECG artifact as follows: 1. Equipment-induced motion artifact: They are due to epidermal stretch-induced voltage change, which can mimic atrial flutter/ventricular tachycardia, for example, IABP, high frequency oscillatory ventilation.…”

“…Static and piezoelectric effects: Piezoelectricity is an electrical charge generated by the mechanical deformation of polymeric materials. Common scenarios are patients on cardiopulmonary bypass [8] and in patients receiving dialysis [5] due to the generation of static and piezoelectric currents in pumps rotating between 50 and 600 rpm. 4.…”

Earthing defect: A cause for unstable hemodynamics

Interference of monitored electrocardiogram (ECG) is a common event in intensive care units and operation theaters. Artifacts in the ECG tracing can resemble serious arrhythmia, thus leading to unnecessary usage of antiarrhythmics or electrical defibrillation. In addition, ECG artifacts may lead to serious hemodynamic consequences secondary to intra-aortic balloon pump (IABP) trigger failure. We report a rare event of IABP failure due to ECG artifact, which appeared on placement of the transthoracic echocardiography probe over the chest. Subsequent evaluation revealed potential current leakage from echocardiography machine secondary to earthing defect in the machine.

“…One common undesired effect due to such equipment interactions is the generation of electrocardiograph (ECG) artefacts 1 . ECG artefacts such as pseudo spikes and more commonly pseudo atrial flutter have been reported during continuous veno‐venous infiltration (CVVH) 2,3 …”
