The term ST-T segment changes (or simply ST-T changes) is used to refer to such ECG changes. It must also be noted that the J point is occasionally suboptimal for measuring ST segment deviation. This is explained by the fact that the J point is not always isoelectric; this occurs if ...
normal ECGpositive hemisphereprecordial planeSummary The neutral plane divides the space around the heart into two halves. The half along the positive side of the lead axis is the positive hemisphere. Any resultant heart vector in that hemisphere has a positive projection upon the lead axis and ...
While based on Italian experience, ESC recommends a resting ECG as part of PPS before competitive sports, AHA still doesn't recommend ECG because of several concerns including feasibility, cost efficiency, high false positive results, and the lack of specially physicians qualified to interpret ECGs ...

On ECG, right axis deviation with normal sinus rhythm was seen. Ebstein Anomaly with Pregnancy: A Rare Case After an asystole episode lasting approximately 10-12 seconds, it was observed that the rhythm spontaneously turned back to normal sinus rhythm but as bradycardic. Atrioventricular Block in...

b The distribution of sleep sessions for the optimal number of clusters, organized by sleep duration (y-axis) and deviation from normal bedtime (x-axis). Full size image Among these two clusters, cluster 1 had a mean sleep duration of 7.03 h and mean bedtime difference of 1.04 h, ...
Since this approach was inconsistent with post-processing recommended by SCMR [9] and other manuscripts on the topic, both studies were excluded from the current analysis. Data at 1.5 and 3 T is now available for normal subjects using bSSFP short axis imaging. Since it has been shown that ...
-180 and 820, T-wave axis 0 to 720 vs. -8 to 730, Sokolow-Lyon index 2.13 to 6.21 mV vs. 1.60 to 4.87 mV, Cornell index 0.17 to 6.24 mV vs. 0.14 mV to 4.35 mV. Conclusions The values described for the electrocardiographic measurements above can act as a ...
