No
This device is a software library that performs analysis of ECG signals and detects various cardiac events. It is integrated into other monitoring devices, but does not itself provide therapy.
Yes
Explanation: The device is described as "analysis capabilities" for "monitoring and detecting" various cardiac events (QRS detection, ventricular ectopic beat detection, rhythm call analysis, ST segment level measurement, ventricular fibrillation detection) from ECG leads. This falls within the definition of a diagnostic device as it processes data to identify conditions or characteristics of a disease.
Yes
The device is described as a "Software Library" and a "collection of callable functions" that is integrated into another computerized cardiac monitoring device. It does not include any hardware components.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are devices intended for use in the examination of specimens derived from the human body (such as blood, urine, or tissue) to provide information for diagnostic, monitoring, or compatibility purposes.
- Device Function: The ST/AR Library analyzes ECG signals captured from the human body surface. This is a direct measurement of electrical activity from the body, not an analysis of a specimen derived from the body.
- Intended Use: The intended use is for integration into a computerized cardiac monitoring device that analyzes these direct ECG signals.
- Anatomical Site: The anatomical site is the "body surface," which aligns with direct physiological measurement rather than specimen analysis.
Therefore, the ST/AR Library is a component of a medical device that performs physiological monitoring and analysis, not an in vitro diagnostic test.
N/A
Intended Use / Indications for Use
The intended user is a medical device manufacturer who will integrate the ST/AR Library into a computerized cardiac monitoring device. The ST/AR Library integrator will ultimately identify the indications for use, depending on the nature of their device.
The analysis capabilities of the ST/AR Library are indicated for monitoring and detecting the following from up to 12 body surface ECG leads for adult, pediatric, or neonatal patients:
- QRS detection.
- ventricular ectopic beat detection (non-paced only).
- rhythm call analysis, including asystole, bigeminy, couplets, irregular heart rate, pause or missed beat, VEB/minute, run, trigeminy, triplets, ventricular tachycardia
- ST segment level measurement (adult patients only).
- ventricular fibrillation detection.

Device Description
The Brentwood Real Time ST and Arrhythmia Analysis Software Library is an "object library'. An object library is a collection of callable functions that have been compiled (or assembled) into the native machine code of the computer on which they will execute. An application software program can be written to invoke some or all of the functions in an object library. The compiled (or assembled) application code can be "linked" to the called functions from an object library at the time the executable code image is built. An executable code image created in this manner will contain the application software code and all of the functions it invoked from the object library.
The Brentwood Real Time ST and Arrhythmia Analysis Software Library consists of a collection of ANSI Standard C (ISO/IEC 9899) callable functions. It provides real time ECG signal processing, QRS detection, QRS complex feature extraction, ventricular ectopic beat detection, ST level measurement, rhythm calls, and ventricular fibrillation detection capabilities for up to 12 leads of captured ECG lead data.
Brentwood will compile the Brentwood Real Time ST and Arrhythmia Analysis Software Library using the compiler specified by an ECG analysis device manufacturer. An object library will be created and delivered to the manufacturer, who can then integrate it into application software for their ECG analysis device(s).
