FIELD: medicine.
SUBSTANCE: invention relates to medicine, namely to cardiology. Method includes measurement of electric impedance of chest by bipolar method. Measurements are carried out at frequency of probing alternating electric current, not lower than 100 kHz. For this purpose electrodes are applied on both halves of chest on parasternal lines at the level of III-IV intercostals spaces. Average values of module impedance |Z| and phase angle |φ| are registered for 1-5 minutes. After that, coefficient |Z||φ| is calculated. If coefficient increases more than 5 times, chronic heart failure is diagnosed.
EFFECT: method ensures increase of early diagnostics accuracy.
