EKG Interpretation Nurses Learning Network

AV Junctional Rhythms with retrograde atrial activation (inverted P waves in II, III, aVF): Retrograde P waves may occur before the QRS complex (usually with a short PR interval), in the QRS complex (i.e., hidden from view), or after the QRS complex (i.e., in the ST segment).

EKG Manual Fall 2007 University of Connecticut

The QRS complex is a name for the combination of three of the graphical deflections seen on a typical electrocardiogram (EKG or ECG). It is usually the central and most visually obvious part of the tracing; in other words, it's the main spike seen on an ECG line.

CHAPTER 3 ECG Statistics Noise Artifacts and Missing Data

The QRS-complex represents depolarisation of the ventricles. It is seen as 3 closely related waves on the ECG (waves Q, R & S). Because the ventricles have a large muscle mass compared to the atria, so the QRS complex usually has a much larger amplitude than the P-wave. The point at which the QRS complex finishes and the ST segment begins is known as the J-point.

The QRS Complex Sinus Rhythm - Normal Function of the

The table below shows an easy way to calculate the heart rate by counting the number of squares between successive ventricular electrical complexes, measured from the gap between R waves - the first upward deflection of the ventricular QRS complex. This is known as the R-R interval.

QRS Complex on a 12-lead ECG Tracing LearntheHeart.com

rhythm can be explained as follows: If the ectopic junctional focus is in the center of the node, the depolarization impulse has to travel an equal distance up and down the node to depolarize the atria and the ventricles. Hence activation of atria and ventricles is simultaneous (conduction down the His bundle and bundle branch is very fast) and the P wave is buried within the QRS complex. If

The S Wave Sinus Rhythm - Normal Function of the Heart

examples of each rhythm will be broken down using the same approach and the basis of the ECG appearances will be explained. The tutorial will also introduce a treatment strategy for arrhythmias. 1) An approach to the diagnosis of an arrhythmia from the ECG . Any rhythm can be determined by asking five simple questions: 1. What is the RATE? 2. Are the QRS complexes REGULAR? 3. Are the QRS

Human ECG Laboratory Experiment By Brittany Baierlein

A narrow QRS complex occurs when the impulse is conducted down the bundle of His and the Purkinje fibre to the ventricles. This results in well organised synchronised ventricular depolarisation. This results in well organised synchronised ventricular depolarisation.

signal is divided into three main portions: the P wave, the QRS complex wave and the T wave. The P wave occurs during a normal atrial depolarization, followed by the rapid depo- larization of the right and left ventricles producing the QRS complex wave and lastly the repolarization of the ventricles which creates the T wave. The different stucture of the heart between individuals affect the

The initial part of the QRS complex is often spared as purkinje fibers are less sensitive to hyperkalemia. These changes can also occur in acidosis (via the same mechanism) and during Class IC anti-arrhythmic intoxication.

In 2010 Joseph Brugada et al. published a new criterion to differentiate VT from SVT in wide complex tachycardias: the R wave peak time in Lead II . They suggest measuring the duration of onset of the QRS to the first change in polarity (either nadir Q or peak R) in lead II.
