The normal length of the QTc is generally less than 460 milliseconds, but this length can vary based on a child's gender, age, and activity and the day of testing While the QT interval is used as one part of LQTS diagnosis, individuals with normal intervals may have LQTS and those with long intervals may not have LQTS For example, at least 10 to 15 percent of individuals with LQTS2700interpreting an ECG Patients age, gender, race, body habitus, heart orientation and physiology can affect the axis of the heart Similarly, technicalities of procedure, posture, temperature, or eating can affect ECG interpretations This analysis was carried out on the normal individual group of another study We needed to knowECG signs of left atrial enlargement 3 Left axis deviation 2 QRS duration ≥90 milliseconds 1 Prolonged Rwave peak time V1V2 (right ventricle) ≥35 milliseconds V5

Millisecond is a time measurement unit with the symbol of ms, which is equal to a one thousandth of a second It can also be defined as the duration of photo flash light, or as the time of a cycle for 1kHz frequency This unit is sometimes used when measuring magnitude or making really precise physical and scientific calculationsThis vector changes every millisecond of the depolarization In the animation vectors for atrial depolarization, ventricular depolarization and ventricular repolarization are shown The different ECG waves The origin of the different waves on the ECG The QRS complex is formed by the sum of the electric avtivity of the inner (endocardial) and the outer (epicardial)The last few milliseconds of the QRS complex are caused by depolarization of the basilar portion of the left ventricle 9 The T wave is produced by repolarization of the ventricles The wave of repolarization moves predominantly from epicardium to endocardium It puzzled scientists for many years why a mean vector representing the T waves was directed in almost the same direction as

On most ECG machines the 'ventricular rate' is written as a number, but it may be worth checking to see this is right If normal ECG paper is being used and the ECG is moving at 25mm/sec, the easiest way to work out the rate is by counting how many 'big squares' you get between R waves Then divide 300 by this number For example, if you have 4 big squares between each R wave, thenGreen line is 15 little boxes, or 60 milliseconds, after the Jpoint Upper black line intersects the tracing where the green line demonstrates 60 ms after the Jpoint Measure voltage difference (black arrows) (1 mm = 01 mV, but we measure in mm) between black linesA common length of an ECG printout is 6 seconds;
