Poor R Wave Progression Revisited

Fully Screen-Printed and Gentle-to-Skin Wet ECG Electrodes with Compact Wireless Readout for Cardiac Diagnosis and Remote Monitoring

“…For example, volunteers 3 and 11 with sinus arrhythmia (Figures S15 and S23), volunteers 5, 8, and 10 with early repolarization (Figures S17, S20, and S22), and volunteer 11 with short PR (Figure S23) were found in all single-lead and 12-lead ECGs confirming that the ECG readout and ECG electrodes are giving the similar information when compared to the commercial single-lead ECG system and electrodes. In the case of volunteer 17, 12-lead ECGs obtained using commercial and screen-printed electrodes detected poor R wave progression (Figures c and S29), often interpreted as indicative but not as a diagnostic and cannot rule out, possible, or probable anterior myocardial infarction (AMI). , Poor R wave progression is usually diagnosed by looking at the lack of progressive increase in amplitude of the R wave from leads V1 to V6. , With poor progression, in lead V4 we can see that the R wave amplitude is smaller than the S wave amplitude, which is evidence of poor R wave progression (Figure c). Poor R-wave progression is a common abnormal ECG finding; however, this cannot be seen using both of the single-lead ECG systems (Figure d) and can only be seen using the 12-lead ECG system.…”
