Description

Subject Subject is female, 27 years old, nonsmoker, BMI= 23.1 (kg/m2), there is a genetic susceptibility in the family to the occurrence of varicose veins. The measurements were made after confirming the varicose in the right leg in the early stages, and the second measurement was made after a five-minute local massage of the leg. Equipment The equipment used is the multi-channel electrical impedance research system REO-32. This system has the following characteristics: 30 precordial electrical impedance channels, one transthoracic bioimpedance channel, one ECG channel, channel sampling rate is 500 HZ, bioimpedance measurement method is tetropolar, probe current amplitude is 1 mA, probing frequency is 100 kHz, pulse impedance measurement range is (−2∼+2) Ohm , and bandwidth of the bioimpedance channel is (0.01∼117) Hz. Channels: Transthoracic ; Right thigh (RLU); Right leg (RL); Lower part of the right leg (RLD); Left thigh (LLU); Left leg (LL); Lower part of the left leg (LLD); ECG. Institutional Review Board Statement: The study that collected the data was conducted according to the guidelines of the Declaration of Helsinki, and approved by the Ethics Committee of Scientific and educational medical-technological center of Bauman Moscow State Technical University (Institutional Review Board Statement No 1 on 28 January 2021). Informed Consent Statement: Informed consent was obtained form subject involved in the study.
