Day-to-Day Variation of the Normal Orthogonal Electrocardiogram and Vectorcardiogram

Day-to-day variation of the normal orthogonal electrocardiogram and vectorcardiogram.

Day-to-day variation of the corrected orthogonial electrocardiogram was investigated in 20 normal subjects. Ten recordings were made in each individual witlh chest electrode positions left unmarked first, after which 10 subjects underwent another series of 10 consecutive daily recordings with marked electrode locations. Mean and maximal day-to-day variations of durations and amplitudes of diffe...

stability and attraction domains of traffic equilibria in day-to-day dynamical system formulation

در این پژوهش مسئله واگذاری ترافیک را از دید سیستم های دینامیکی فرمول بندی می کنیم.فرض کرده ایم که همه فاکتورهای وابسته در طول زمان ثابت باشند و تعادل کاربر را از طریق فرایند منظم روزبه روز پیگیری کنیم.دینامیک ترافیک توسط یک نگاشت بازگشتی نشان داده می شود که تکامل سیستم در طول زمان را نشان می دهد.پایداری تعادل و دامنه جذب را توسط مطالعه ویژگی های توپولوژیکی تکامل سیستم تجزیه و تحلیل می کنیم.پاید...

Day to day variation in 3 orthogonal lead electrocardiogram parameters after acute myocardial infarction.

Serial 3 orthogonal lead electrocardiograms were recorded on 67 patients with acute myocardial infarction. For each series of electrocardiograms, the day to day changes and the changes with respect to the initial computer measurements of selected ST-T segment amplitudes and vector orientations were investigated. The results indicated that the degree of rotation of ST-T vectors, which correspond...
