Important Normal Values for ECG

Transcript of the video: Normal values for ECG will depend on the age, body size, gender, as well as the population being assessed. So there is a wide variation. Still, in a normal adult population, some normal values are useful, while assessing an ECG. These are the normal waves which you expect on the ECG and normal heart rate in an adult is 60 to 100 per minute. P wave, the atrial activation, PR segment, QRS complex – ventricular activation, ST segment, and T wave, ventricular repolarization. Atrial repolarization wave is usually not seen in a standard surface ECG. It will somewhere in the ST segment (error: PR segment) and part of the QRS, of low amplitude. Usually, the Ta wave, that is the atrial repolarization wave, is not seen in a surface ECG. This is P wave, this is QRS complex and T wave. A segment does not include a wave. PR segment, ST segment. But an interval includes one or more waves and a segment. PR interval will include P wave and PR segment. QT interval will include QRS complex and ST segment as well as the T wave. So interval includes one or more waves and one segment, while segment is without a wave. And there is another one which is not represented here. Part of it is seen here, that is the TP segment. Previous T to the current P. That is the true isolectrical interval, isoelectric interval in the ECG. True isoelectric interval in the ECG is TP segment. While PR and ST are not, even though it is shown as isoelectric in this diagram, they are not tr...
