Figure 3

The figure shows a standard ECG (A) and a compared “12-lead equivalent ECG” (B) from the same patient using 2 electrodes connected to a smartphone associated sensor as shown (C) that obtains multiple sequential single-lead ECG measurements that was used in the St. Leuis trial. A next-generation concept for improved detection from AliveCor (Mountainview, CA, USA) is shown in (D) for smart phone-based cordless detection of STEMI with direct lead equivalents annotated.
