The 24 h ECG is used for the continuous recording of the cardiac rhythm over 24-80 hours. For this purpose a small device is placed in the ordination, which is worn for 24 to 80 hours. The ECG is then analyzed.

Thus, cardiac arrhythmias can be detected, even if they have not occurred at the time of the doctor’s visit. The LZ-ECG analysis can also provide information on blood flow problems at the heart muscle.
