Key result
BCG-based pulse transit time was significantly better correlated with diastolic blood pressure than ECG-based pulse arrival time across all distal timing references (p=0.01).
Why the study?
Does BCG-based PTT measurement improve correlation with blood pressure compared to ECG-based PAT in healthy volunteers?
Cross-Sectional (n=15)
Does BCG-based PTT measurement improve correlation with blood pressure compared to ECG-based PAT in healthy volunteers?
p-value: p=0.01
BCG-based PTT provides an adequate proximal timing reference that may be superior to ECG-based PAT for estimating diastolic blood pressure, offering potential for cuffless BP monitoring.

BCG-PTT may improve diastolic BP correlation in healthy volunteers; hypothesis-generating for cuffless monitoring.
Kim et al. (2015) conducted a cross-sectional in Healthy volunteers (n=15). Ballistocardiogram (BCG)-based pulse transit time (PTT) vs. Electrocardiogram (ECG)-based pulse arrival time (PAT) was evaluated on Correlation with diastolic blood pressure (p=0.01). BCG-based pulse transit time was significantly better correlated with diastolic blood pressure than ECG-based pulse arrival time across all distal timing references (p=0.01).
