EKG P-WAVE CHANGES: AN EARLY INDICATOR OF END ORGAN DAMAGE.Chockalingam, AFodor, J.G
These changes in the locus of stimulation within the atria affect the morphology of the P waves. Remember, you must observe at least three different shaped P waves. Due to the presence of irregular R to R intervals coupled with the changing P wave morphology, so...

And here is a teaser to whet your interest; when you see an abnormal P wave, consider, strongly, the presence of atrial changes such as myocardial enlargement (Davey, 2018). P-R Interval. "P-R" Interval represents the time from the start of atrial depolarization, P wave, to the ...
A myriad of EKG changes have described as associated with heat stroke [25], [26] including sinus tachycardia, ST elevations, T wave inversions and QT prolongation. However, these changes are non-specific, seen with a number of other conditions and have been often attributed to accompanying elec...
The typical amplitude of the R wave component of the EKG signal is approximately 1 mV [3]. This peak is located within a group of peaks known as the QRS complex and represents the electrical pulse flowing through the ventricles. As this pulse travels through the blood stream, it can be ...
