A method for detecting the myocardial state of a heart with a measuring apparatus which includes inserting a bipolar cardiological measuring electrode (4) into a heart division (8) at an acute attachment angle (9) on the myocardium (6) of less than 90°, measuring a cardiological stimulation signal such as an IEGM in sequential cardiac cycles, and in addition, determining the positive and negative maximum amplitudes Vp and Vn of the IEGM, ascertaining an asymmetry factor η of the stimulation signal (IEGM) of sequential cardiac cycles according to the equation η=(Vp−|Vn|)/(Vp+|Vn|) and storing the asymmetry factor η of sequential cardiac cycles for analysis.
