ACME -Model NID -Non-invasive Ischemia Detector
ACME Non-invasive Ischemia Detector (ACME NID) is a reliable, non-invasive tool for ischemia detection algorithm. It is a patented algorithm that analyzes 10 second 12 lead ECG captured by either our own QED 2000 or a certified off-the-shelf ECG machine, and it aims to assist in detection of myocardial ischemia related to Coronary Artery Disease (CAD).
The ACME NID revolutionizes the field of non-invasive coronary artery disease diagnosis in several ways:
- Reduced door-to-balloon time to speed up treatment. The ACME NID is a quick and highly sensitive ischemia detection tool. It can be used in the ER to screen chest complaint patient. In the past, it would take 90 minutes to get results. Now, in just a minute, the doctor can get an analytical report and make a prompt decision for treatment.
- The ACME NID prevents unnecessary nuclear or invasive procedures in patients. Using the ACME NID, you have the same levels of sensitivity, specificity, and accuracy as those from radioactive procedures.
- Using the ACME NID significantly reduces health care system costs. Accurate diagnosis by the ACME NID saves both time and cost of other test tools.
- No additional workload. The ACME NID testing operation is the same as the conventional 12 lead resting ECG test. However, conventional methods cannot test for the probability of ischemia. Our QED 2000 with NID can do this and therefore, produces two results.
The ACME NID is a high-resolution ECG acquisition hardware, employing a sampling rate of 1000Hz. It uses frequency domain processing to predict ischemia. This process can be broken down into two steps. The first step is Time-frequency operation, which extracts 12 lead ECG signals from J point to T peak and takes the ST segment. The second step uses a logistic regression method to determine the risk of ischemia in the area.
