Conclusions: ST-T abnormalities without apparent heart diseas may be considered to be nonspecific but this cross-sectional study showed that they are related to CVRs and may be used as an early marker of preclinical cardiac damage by CVRs....

there are actually “silent” electrical areas of the heart. For example, parts of the muscle may become ischemic, and the 12-lead ECG may be entirely normal or show only nonspecific changes even while the patient is experiencingangina pectoris(chest discomfort due to an episode of myocardial ...
QRS Complex: May be regular or wide if there is an underlying abnormality. There is a P-wave for every QRS complex. Rhythm: Regular sinus. PR Interval: Usually <0.20 seconds.Clinical ManifestationsNonspecific for tachycardia. Symptoms may be present due to the cause of the tachycardia (fever,...
