A method of estimating blood pressure of a user, the method including the steps of: injecting current into the user's body via a pair of current injection electrodes affixed to the user's upper body, receiving an electrocardiogram (ECG) signal from an ECG electrode affixed to the user's upper body, receiving at least one pulse signal related to pulse wave velocity (PWV) of a pressure pulse generated by a cardiac contraction, determining, from the ECG signal, instances of electrical stimulation of the user's heart; determining, from the least one pulse signal, corresponding instances of arrival at the user's carotid artery of a pulse wave; computing the pulse arrival time (PAT) from the instances of electrical stimulation and one or more corresponding instances of pulse wave arrival from the least one pulse signal; and estimating the blood pressure from the computed PAT. |
