ABSTRACT
<p><b>OBJECTIVE</b>To compare the heart rate variability (HRV) measurements between ballistocardiogram (BCG) and electrocardiography (ECG).</p><p><b>METHODS</b>The signals of BCG and ECG of 21 patients were collected synchronously. JJ intervals of BCG and RR intervals of ECG were used to calculate the cardiac periods. The parameters of HRV analysis were calculated in time domain analysis, frequency domain analysis and nonlinear analysis. The results derived from BCG and ECG were compared.</p><p><b>RESULTS</b>The parameters of HRV analysis calculated from BCG and ECG had high similarity. The correlation coefficients of SDNN, TP, LF, HF and SD2 between the BCG and ECG methods were high (r = 1). The correlation coefficients of rMSSD and SD2 were 0.99 and of PNN50 and LF/HF were 0.98 between the two methods. HRV analysis results derived from the two methods were similar (P > 0.05).</p><p><b>CONCLUSION</b>HRV could also be measured reliably by calculating the JJ interval from BCG.</p>
