No
The document describes a "Classification software" which provides an indication of positive, negative, or indeterminate results. While classification is a common task for AI/ML, the description does not explicitly mention AI, ML, or any related technologies (like DNNs). The software was cleared in 2001 (K012206), which predates the widespread adoption of AI/ML in medical devices. The description focuses on signal processing and measurement techniques (Analytic Spectral Method) rather than learning algorithms.
No
The device is described as an "Alternans Processing System" used for measurement and diagnosis, specifically to predict risk, not to treat or alleviate a medical condition.
Yes
The device description explicitly states, "The Heartwave™ Alternans Processing System provides T-wave alternans diagnostic capabilities to standard stress labs." Additionally, its intended use is to predict increased risk of a cardiac event, which is a diagnostic purpose.
No
The device description explicitly mentions "seven standard stress test electrodes and seven proprietary multi-segment Micro-V Alternans™ Sensors" and a "belt-worn patient module" which are hardware components.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD devices are used to examine specimens derived from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening. The Heartwave™ Alternans Processing System measures electrical signals from the heart through electrodes and sensors attached to the patient's skin. It does not analyze biological specimens.
- The device description focuses on processing and analyzing ECG signals. It describes the use of electrodes and sensors to capture electrical activity and the software used to process this data.
- The intended use is to measure Microvolt T-Wave Alternans directly from the patient. This is a physiological measurement, not an in vitro test.
Therefore, the Heartwave™ Alternans Processing System falls under the category of a medical device that performs a physiological measurement, rather than an in vitro diagnostic device.
N/A
Intended Use / Indications for Use
The Heartwave™ Alternans Processing System is intended for the measurement of Microvolt T-Wave Alternans* at rest and during ECG stress testing.
The presence of Microvolt T-wave Alternans as measured by the Analytic Spectral Method of the Heartwave™ Alternans Processing System in patients with known, suspected or at risk of ventricular tachyarrhythmia predicts increased risk of a cardiac event (ventricular tachyarrhythmia or sudden death).
The Heartwave™ Alternans Processing System should be used only as an adjunct to clinical history and the results of other non-invasive and/or invasive tests. The interpretive results of the Alternans Processing System should be reviewed by a qualified physician.
The predictive value of T-wave Alternans for cardiac events has not been established in patients with active, untreated ischemia.
