answers Of A Shortened electrocardiogram S-T Segment And Its Effect On Ventricular Repolarization

April 11, 2011

Abstract
Electrocardiogram ( electrocardiogram) waves represent the depolarization and repolarization of the atria and ventricles. The hesitation posed in this paper is to check off whether any ab approach patternities comprise with a shortened ECG S-T segment and what effect it may have with ventricular repolarization. ECG measurements of star healthy upshot was taken at various phases of watch rate: resting, session up, deep breathing and post exercise and then comp argond to normal ranges. ECG components calculated included P wave duration, P-R interval, QRS interval, Q-T interval, R-R intervals, T wave duration and End of T wave to fount of next R wave. Based on the findings of other researchers, what is pass judgment is that individuals who have an S-T segment below the normal range are likely to have an abnormality in ventricular repolarization.

Introduction
As the heart undergoes depolarization and repolarization, the galvanic currents that are generated spread not only within the heart, but also throughout the body.1  This electrical activity generated by the heart can be measured by an array of electrodes placed on the body surface. The put down tracing is called an electrocardiogram (ECG, or EKG).



  A typical ECG tracing is shown at the beginning of this paper.  The different waves that comprise the ECG represent the sequence of depolarization and repolarization of the atria and ventricles. Finding out how wish a wave takes to travel from one part of the heart to the next shows if the electrical activity is normal or slow, sporting or irregular.2
The purpose of this paper is to consider the ECG components of one subject and compare it to normal ranges. Of particular interest is to determine if individuals who have an S-T segment below the normal range are likely to have an abnormality in ventricular repolarization.
