We also recorded ECG signals under 12 conditions (standard, two conditions shifting precordial electrodes, five conditions moving limb electrodes to the torso, three conditions contaminating noise, and reproducibility over 15\u2009min) in 30 participants to evaluate changes from the standard. The results of the AF risk estimation are expressed at four levels.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The rate of participants within one level of error was 95% for reproducibility within 4\u2009min and 87% for reproducibility over 15\u2009min. Shifting the precordial electrodes upward or downward and replacing the left leg electrode with the torso electrode frequently caused a two\u2010 or three\u2010level change. In clinical information, increased brain natriuretic peptide tended to increase the variability.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The AF risk estimated by the AI\u2010based program exhibited temporal variability.
