This step helps to find candidates of QRS waves
more precisely and contributes a lot to QRS detection.
Through calculation, it can be concluded that 76% of total energy is accumulated near 9.4 Hz-19.4 Hz of QRS wave
. It can utilise the bandpass to extract the signal of this frequency section, where after the signal is enhanced, amplified, and processed, the higher identification can guarantee the signal is accurately locked.
Each curve was segmented into separate for the intervals of P wave, T wave and QRS wave
the individual and clear identification.
Studies have compared the cardiac functioning of endurance athletes with speed athletes mentioning that endurance athletes show a better cardiac functioning shown by their systolic and diastolic function [6-8] but not by relating the two variables V[O.sub.2] max and QRS wave
amplitude in a 12-lead ECG.
Normal [arrow up]> [arrow down]< (120-200 msec) 200 msec 120 msec Athletes--50 48 2 -- Non-Athletes--50 50 0 0 QRS Duration: Normally- The QRS wave
's duration is 0.08-.12 sec (80-120msec).
Corrected QT was calculated by dividing the time measured in milliseconds of the interval from the beginning of QRS wave
until the end of the T wave by the square root of the value in milliseconds of the interval of two successive R waves.
For patients with symptomatic arrhythmias, the updates now recommend adenosine for diagnosing and treating stable undifferentiated wide-complex tachycardia when the rhythm is regular and the QRS wave
