Continuous electrocardiographic monitoring is a basic part of medical care practices in operating rooms and other intensive care environments. Over the previous decades these environments have been equipped with more advanced medical technology for the enhancement of patient care. As a result, there has been a concern about the potential interferences that could occur between different devices. An accurate electrocardiogram (EKG) reading depends on the results being free from distortion. Potential interference due to electrocautery interference is an issue to be addressed. At Danlee Medical Products, Inc., we offer an array of ECG electrodes for use by cardiology care professionals.
Below we address the potential problem of electrocautery interference connected with the positioning of ECG electrodes.
Definition of Electrocautery?
Thermal cautery is another term for electrocautery. This process consists of direct or alternating current that is sent through a resistant metal wire electrode which results in the production of heat. This heated electrode, when contacting living tissue, produces hemostasis or tissue destruction. Various surgical procedures can make use of this process, including those involving the practice areas of dermatology, urology, ophthalmology, otolaryngology, and plastic surgery.
Current does not move through the patient during the electrocautery process. It is conveyed through a heating element via direct heat transfer, burning tissue. Electrocautery units are disposable or reusable units powered by a battery. This procedure is safe for use in patients carrying implanted electrical devices (such as pacemakers) in their bodies.
Electrocautery-Induced Interference on the ECG
An electrocardiogram experiences electrical interference (electrocautery-induced) primarily because of very high frequency currents that heat the range of radiofrequency between 800 and 1000 kHz. Additional factors that can produce electrical interference include low frequency noise between 0.1 and 10 Hz and noise from powerlines between 50 and 60 Hz.
Advancements in technology are needed to negate and potential issues in medical settings due to the influence of radiofrequency, static, and electromagnetic interference.
