1. A computer program product, tangibly embodied on computer-readable media, the computer program product being operable to cause a data processing apparatus to:
receive bioimpedance information of a subject;
determine a rate of change of blood flow based on the bioimpedance information;
determine if the rate of change of blood flow includes at least two peaks during the systole of the subject;
if the rate of change of blood flow includes at least two peaks, determine a time based on at least one of the two peaks; and
compare the determined time to a threshold time.
