Intended Use

The GE 12RL program generates a 12-lead ECG report from a subset of the electrodes used to acquire a standard 12 Icad ECG. Four of the precordial channels of the 12-lead ECG (V2, V3, V4, V6) are not acquired from the patient; rather, they are reconstructed from information that is directly recorded in the other channels of the 12-lead ECG. The four signals generated by the GE 12RL program are similar but not identical to the standard 12-lead ECG. All ECG data generated via 12RL are clearly identified as to which channels have been synthesized. The GE 12RL program is intended for use in a monitoring environment. Computerized measurements may be generated from these data; however, a computerized interpretation will not. The product is intended for use in the general adult population ranging from healthy subjects to patients with cardiac and/or non-cardiac abnormalities. The product is to be used in conjunction with the patient's clinical history, symptoms, and other diagnostic tests for final clinical judgment.

Device Story

12RL program reconstructs 4 precordial ECG channels (V2, V3, V4, V6) from remaining recorded channels using linear equations; enables 12-lead ECG presentation from reduced electrode set. Used in clinical monitoring environments; operated by healthcare professionals. Outputs 10-second records or continuous recordings for ST segment trending. Synthesized channels clearly identified in reports. Computerized measurements supported; automated interpretation excluded. Used alongside clinical history and diagnostic tests for final clinical judgment. Benefits include reduced electrode burden while maintaining 12-lead diagnostic utility.

Clinical Evidence

Bench testing only. No clinical data provided. Compliance with voluntary standards and software verification/validation testing confirmed performance equivalent to predicate devices.

Technological Characteristics

Software-based algorithm using linear equations to reconstruct ECG signals. Operates on standard ECG monitoring hardware. Connectivity: Integrated into monitoring systems. Software verification/validation performed.

Indications for Use

Indicated for general adult population, including healthy subjects and patients with cardiac or non-cardiac abnormalities, in a monitoring environment to reconstruct 12-lead ECG reports using a subset of electrodes.

Regulatory Classification

Identification

A cardiac monitor (including cardiotachometer and rate alarm) is a device used to measure the heart rate from an analog signal produced by an electrocardiograph, vectorcardiograph, or blood pressure monitor. This device may sound an alarm when the heart rate falls outside preset upper and lower limits.

The 12RL feature is intended to reconstruct electrocardiograph Device Description: (ECG) signals such that a 12-lead ECG presentation can be made when at least six electrodes are attached to a patient. These 12-lead ECGs may be 10 second records or continuous recordings suitable for ST segment trending.

- Technology: The 12RL technology is based on linear equations as is used by the predicate devices. Therefore there is no change in technology.
- The 12RL complies with the voluntary standards as detailed in Test Summary: Section 9 of this submission. The following quality assurance measures were applied to the development of the 12RL program:
- Risk Analysis .
- Requirements Specification Review .
- Code Inspections .
- Software Verification and Validation Testing .
- The results of these measurements demonstrated that the 12RL Conclusion: program is as safe, as effective, and performs as well as the predicate device.
