It may also be useful for those who are not responsible for interpreting 12-lead ECGs but want to learn more about the capabilities and limitations of this medical device. See Contents for more details.  \nManual Purpose: Ancillary Documentation, Product Labeling  \nGE’s Marquette 12SL ECG Analysis Program is a prescriptive class II medical device, cleared by the Food and Drug Administration (FDA) . The 12SL program does not directly acquire the ECG signal. It is used as a component in devices such as electrocardiographs, which digitize the analog ECG, and in computer systems, which receive digital 12-lead ECGs from other sources so that an initial ECG interpretation can be generated by 12SL for review and correction by a physician.  \nThe International Electrotechnical Commission (IEC) requires manufacturers to disclose the performance of ECG analysis programs used in diagnostic electrocardiographs. “The intent is that this performance information be readily available to customers who want to know the information. The intent isnot to require expansion of OPERATOR documentation to include this performance information. This information may be disclosed in one of the documents that are created and made generally available by the manufacturer of an ELECTROCARDIOGRAPH. Examples of these documents are physician’s guidesand technical notes, in addition to the OPERATOR’s guide.”[1]  \nThis 12SL Physician’s Guide is not an operator manual. It is ancillary to the operator’s manual and is considered product labeling. What the FDA terms“product labeling” extends beyond what is printed on the medical device or in an operator manual. It is brochures or any material regarding the product. If a manufacturer discloses the accuracy of the program in its Physician’s Guide, it needs evidence to support it.  \nIntended Use of Computerized ECG  \nComputerized electrocardiography has been in existence since the late 1950’s. [2 , 3] Despite its widespread use,[4] there is little written that directly addresses the intent of computerized electrocardiography.  \nThe pioneers of this technology had motivations which ranged from the esoteric- like demonstrating that a computer could mimic human intelligenceto the basic need of recording artifact free tracings. [5] Some of the favorable developments which resulted from the evolution of this technology were hardly imagined at","cbCaijw6TlVxMCYX","https://ap.wps.com/l/cbCaijw6TlVxMCYX","pdf",8852836,334,"English","# Publication Information\n# Intended Audience\n# Manual Purpose\n## Intended Use of Computerized ECG\n# Intended Use of 12SL Program as Registered with FDA\n# Bibliography","[{\"question\":\"Who is the intended audience for the Marquette 12SL Physician’s Guide?\",\"answer\":\"Qualified healthcare professionals using the 12SL ECG Analysis Program.
