Intended Use

Acute Cardiac Ischemia Time-Insensitive Instrument (ACI-TIPI ) Option is intended to be used in a hospital or clinic environment by competent health professionals . TIPI utilizes recorded ECG data along with patient demographic and chest pain status to produce a numerical score which is the predicted probability of acute cardiac ischemia. Like any computer-assisted ECG interpretation program, the Marquette ACI-TIPI evaluation and probability score is intended to supplement, not substitue for the physician's decision process. It should be used in conjunction with knowledge of the patient's history, the results of a physical examination, the ECG tracing, and other clinical findings. ACI-TIP! is intended for adult patient populations.

Device Story

ACI-TIPI is a software option for Marquette MAC-series electrocardiographs; used in hospital/clinic settings by healthcare professionals. Input data includes patient age, gender, chest pain status, and ECG features. The device processes these inputs to calculate a numerical score representing the predicted probability of acute cardiac ischemia. Output is provided to the physician to supplement clinical decision-making; it does not replace professional judgment. The device assists in the assessment of patients with chest pain, potentially aiding in the identification of unstable angina or myocardial infarction.

Clinical Evidence

Bench testing only. Quality assurance measures included requirements specification review, software testing, and field tests of the ACI-TIPI analysis. No clinical trial data provided.

Technological Characteristics

Software option for Marquette MAC-series electrocardiographs. Operates as a diagnostic, programmable computer algorithm. Utilizes patient demographics, chest pain status, and ECG signal features to compute a probability score.

Indications for Use

Indicated for adult patients presenting with chest pain in hospital or clinic settings to assist clinicians in predicting the probability of acute cardiac ischemia (unstable angina pectoris or acute myocardial infarction).

Regulatory Classification

Identification

A needle electrode is a device which is placed subcutaneously to stimulate or to record electrical signals.
