end part of the ECG ventricular complex Explanation: Changes in the end part of the ECG ventricular complex under the effects of physical loading https://pubmed.ncbi.nlm.nih.gov/5437168/ -------------------------------------------------- Note added at 13 мин (2020-09-28 20:00:40 GMT) -------------------------------------------------- The QRS complex is the combination of three of the graphical deflections seen on a typical electrocardiogram (ECG or EKG). It is usually the central and most visually obvious part of the tracing; in other words, it's the main spike seen on an ECG line. It corresponds to the depolarization of the right and left ventricles of the human heart and contraction of the large ventricular muscles. In adults, the QRS complex normally lasts 60 to 100 ms; in children and during physical activity, it may be shorter. The Q, R, and S waves occur in rapid succession, do not all appear in all leads, and reflect a single event and thus are usually considered together. A Q wave is any downward deflection immediately following the P wave. An R wave follows as an upward deflection, and the S wave is any downward deflection after the R wave. The T wave follows the S wave, and in some cases, an additional U wave follows the T wave. To measure the QRS interval start at the end of the PR interval (or beginning of the Q wave) to the end of the S wave. Normally this interval is 0.08 to 0.10 seconds. When the duration longer is it considered a wide QRS complex. https://en.wikipedia.org/wiki/QRS_complex -------------------------------------------------- Note added at 14 мин (2020-09-28 20:02:31 GMT) -------------------------------------------------- The QRS complex is the combination of three of the graphical deflections seen on a typical electrocardiogram (ECG or EKG).
