We developed one such version that extracted EEG alpha level as well as EKG R-wave spikes in real-time and provided feedback on alpha level and heart rate via haptics and audio. The same ARM9 microprocessor that was used in the lab setup was also used in the mobile version, and the ...
Figure 1. T-peak to T-end interval according to ajmaline challenge test result. The QT interval, the corrected QT interval, and the S-wave duration in suspected BrS patients were also not significantly associated with a positive response to the test (QT: Neg 412.2 ± 35.0 ms vs. Pos 40...
