Abstract

Problems of measuring pulse wave velocity and its utilization in diagnostics have been examined for many years. Pulse wave velocity is a quantity that can be measured non-invasively, and it may bring much information about the state of circulatory system. The R-wave of electrocardiogram (ECG) is most frequently used as the reference point for measuring the pulse wave velocity but it can also be measured as the phase shift of two pulse waves on one artery. When the pulse wave velocity is brought into correlation with blood pressure, then the method used for long term blood pressure monitoring plays an important role. In many cases, the problem of the artery branching is neglected, although this phenomenon may cause additional mistakes in final results.
