A longitudinal and cross-section investigation on peritoneal dialysis patients: Does the cardiovascular conditions affect on ECG biometrics?

Electrocardiogram is previously verified as a new biometric for human identification. However, it is uncertain if changes of cardiovascular conditions may cause any difference. The research investigates if cardiovascular conditions may impact ECG biometrics. A longitudinal and cross-section investigation is applied on peritoneal dialysis patients. Our results show that ECG is still able to identify individuals, even the average correlation coefficients decreased after years. However, we still suggest that ECG biometric may calibrate after years on peritoneal dialysis patients.
