If there is any fresh change or serious arrhythmia, the test is postponed. Some changes from the conventional ECG is expected as the limb electrodes are placed on the torso rather than on the extremities. There will be a mild rightward shift of the axis and hence Q waves in the inferior leads may diminish or disappear. Basal heart rate and blood pressure are printed on the pretest ECG.<br \/>\nIn standard Bruce protocol for treadmill exercise test, the speed and gradient increases every three minutes. Hence the ECG is recorded at the end of two minutes in each stage to achieve a steady state at that particular level of exercise.<br \/>\n<a href=\"https:\/\/johnsonfrancis.org\/professional\/wp-content\/uploads\/2008\/12\/summary.jpg\"><img loading=\"lazy\" decoding=\"async\" width=\"500\" height=\"161\" class=\"size-medium wp-image-19490 aligncenter\" src=\"https:\/\/johnsonfrancis.org\/professional\/wp-content\/uploads\/2008\/12\/summary.jpg\" alt=\"\" srcset=\"https:\/\/johnsonfrancis.org\/professional\/wp-content\/uploads\/2008\/12\/summary.jpg 500w, https:\/\/johnsonfrancis.org\/professional\/wp-content\/uploads\/2008\/12\/summary-300x97.jpg 300w\" sizes=\"auto, (max-width: 500px) 100vw, 500px\" \/><\/a><br \/>\nThe summary page shows all the stages including recovery, the speed and gradient in each stage, heart rate and the METS achieved. 1 MET is the basal metabolic equivalent and corresponds to 3.5 ml\/kg\/min of oxygen utilization.
