Key result
New P-lead increases P-wave RMS by ~29% vs Lead II without reducing QRS and STT.
Why the study?
A method to detect the optimal bipolar electrode placement for improved recording of the P-wave was needed to enhance atrial activity detection.
Does a newly developed P-lead improve P-wave signal strength compared to standard ECG leads in healthy subjects?

Absolute Event Rate: 93% vs 72%
p-value: p=<0.001
A novel bipolar ECG lead configuration significantly improves P-wave signal strength, which may enhance the detection and monitoring of atrial arrhythmias.

May enhance atrial arrhythmia detection in monitoring; leaves open validation in patients and effects on clinical outcomes.
Finlay et al. (2015) conducted a cross-sectional in Healthy subjects (n=229). P-lead (optimal bipolar electrode placement) vs. Lead II was evaluated on Median P-wave root mean square (RMS) (p=<0.001). The newly developed P-lead significantly improved median P-wave RMS compared to Lead II (93 vs 72 μV, p < 0.001) without reducing QRS and STT RMS.
