    • A early diagnosis device (100) of cardiopathies in a patient (50) such as a cardiac decompensation and/or cardiovascular diseases comprises a wearable support (1) and a diagnostic unit (5) mounted to the wearable support (1). The diagnostic unit (5) comprises a means for delivering (10) an electric current stimulus (Ii), at a predetermined frequency (fi) to the patient's body (50) and a means for measuring (20) a thoracic electrical bioimpedance (Zi), which is adapted to provide a bioelectric impedance signal (Zi) on the basis of the electric stimulus (Ii) at the predetermined frequency (fi). The device (100) further comprises an adjustment means (30) for adjusting the frequency (fi) of the electric stimulus (Ii) in way suitable for transmitting a plurality of electric stimuli (I1, I2,... In) at respective different frequencies (f1, f2, f3... fn) and such that the means for measuring (20) detects a corresponding complex bioimpedance signal (Z1, Z2, Z3, Zn). In addition, the device comprises a memory (35) that is configured to store the complex bioimpedance signals at a first time (ti), at a second time (t2) and at an nth time (tn) and a means for extracting the real part (R1, R2, R3... Rn) of the complex signals for instants (t1, t2, tn), to obtain a respective time chart (C1, C2, Cn) of the real part for each frequency. Furthermore, it comprises a means for analysing (40) the time chart (C1, C2, Cn) and a means to provide an alarm (46) of cardiac decompensation if a decrease value DR/Dt is higher than a predetermined value DRo/Dt.
    • 患者(50)中的心脏病的早期诊断装置(100),例如心脏代偿失调和/或心血管疾病,包括安装在可穿戴支架(1)上的可穿戴支架(1)和诊断单元(5)。 诊断单元(5)包括用于以预定频率(fi)向患者身体(50)输送(10)电流刺激(Ii)的装置和用于测量(20)胸部电生物阻抗(Zi)的装置 ),其适于基于在预定频率(fi)的电刺激(Ii)提供生物电阻抗信号(Zi)。 装置(100)还包括调整装置(30),用于以适合于在各自不同的方式发射多个电刺激(I1,I2,... In)的方式调节电刺激(Ii)的频率(fi) 频率(f1,f2,f3 ... fn),并且使得用于测量的装置(20)检测相应的复数生物阻抗信号(Z1,Z2,Z3,Zn)。 另外,该装置包括存储器(35),其被配置为在第一时间(ti),第二时间(t2)和第n时间(tn)存储复杂的生物阻抗信号,以及用于提取真实的装置 (t1,t2,tn)的复信号的部分(R1,R2,R3 ... Rn),以获得每个频率的实部的各自的时间图(C1,C2,Cn)。 此外,如果减少值DR / Dt高于预定值DRo / Dt,则其包括用于分析(40)时间图(C1,C2,Cn)的装置和用于提供心脏代偿失真的警报(46)的装置 。
