      Electrocardiogram (ECG) has been regarded as a source of respiratory information with the main focus in the estimation of the respiratory rate. Although little research concerning the estimation of\u00a0tidal volume<\/strong>\u00a0(TV) has\u00a0been conducted, there are several ECG-derived features that have\u00a0been related with TV in the literature, such as ECG-derived\u00a0respiration,\u00a0heart rate variability<\/strong>\u00a0or respiratory rate.<\/p>\n

      In this\u00a0work<\/strong>, we exploited these features for estimating TV using a\u00a0linear model. 25 young (33.4 \u00b1 5.2 years)\u00a0healthy male\u00a0volunteers<\/strong>\u00a0were recruited for performing a maximal (MaxT) and\u00a0a submaximal (SubT) treadmill stress test, which were conducted\u00a0in different days. Both tests were automatically segmented in\u00a0stages attending to the heart rate. Afterwards, a subject-specific\u00a0TV model was calibrated for each stage, employing features from\u00a0MaxT, and the model was later used for estimating the TV in\u00a0SubT.<\/p>\n

      During exercise, the\u00a0different proposed approaches<\/strong>\u00a0led to relative fitting errors lower than 14% in most of the cases\u00a0and than 6% in some of them. Low achieved fitting\u00a0errors suggest that TV can be estimated from ECG during a\u00a0treadmill stress test<\/strong>. The results suggest that it\u00a0is\u00a0possible to estimate TV\u00a0<\/strong>during exercise using only ECG-derived\u00a0features.<\/p>\n
