15lead wearable Holter recorder for more comprehensive, accurate and convenient monitoring of ECG signals —

In 2014, the American College of Cardiology (ACC) and the American Heart Association (AHA) published the Guidelines for the Management of Patients with Non-ST-Elevation Acute Coronary Syndrome (NSTE-ACS), which clearly states: Patients with intermediate/high-risk ACS (acute coronary syndrome) without initial diagnostic ECG results should be supplemented with V7, V8, and V9 leads.

and published in Am Hear 1999 Nov as early as November 1999; 138 (5 Pt 10;934-40.) In the article "15-lead ECG improves the diagnosis of posterior wall myocardial ischemia", the researchers found that the sensitivity of 12-lead ECG for diagnosing posterior myocardial injury can be increased from 32% to 57% as long as 3 posterior wall leads are added. Compared with the lower lateral wall lead, the specificity of V7-V9 leads for the diagnosis of circumflex occlusion is very high, reaching 99%.
