In a device and a method for providing correlated measures for predicting potential occurrence of atrial fibrillation, an impedance of the patient is measured to obtain impedance information cardiogenic data is determined from the information respiratory data is determined from the information at least one hemodynamic measure is calculated from the cardiogenic data and at least one apnea measure is calculated from the respiratory data the hemodynamic and apnea measures are correlated such that the correlated measures can be utilized for predicting potential occurrence of atrial fibrillation.
