AI Article Synopsis
- The Cardiovise 2.5 algorithm is designed to detect prior myocardial infarction (MI) using a combination of QRS and T wave criteria, as part of a cardiac diagnostic system from Inovise Medical.
- In a study with 105 patients who had prior MI and 98 who did not, the algorithm achieved a sensitivity of 79% and specificity of 97%.
- Its performance outpaced that of six human readers and two other ECG diagnostic algorithms, showing significant advantages in detecting prior MI.
Article Abstract
The investigators report the diagnostic performance of the latest version (Version 2.5) of the recently developed Cardiovise algorithm for detecting prior myocardial infarction (MI). The Cardiovise 2.5 prior MI algorithm, a component of Cardiovise Cardiac Diagnostic System (Inovise Medical, Inc, Newberg, OR), uses scalar QRS, scalar T wave, and vectorcardiographic QRS criteria for detecting, sizing, and localizing prior MI. In this study only the detection part of the algorithm's performance was evaluated, using 105 patients with and 98 patients without prior MI as indicated by the results of cardiac imaging with Sestamibi. The specificity, and sensitivity of Cardiovise 2.5 for detecting prior MI in this population of patients are 97% and 79%, respectively. The sensitivity and overall diagnostic performance of Cardiovise 2.5 was significantly better than those of a total of 6 human readers (3 cardiologists and 3 primary care physicians) and to 2 commercially available ECG diagnostic algorithms.
