QRS complex ECG (EKG) interpretation and measurement explained. In this ECG interpretation review, you'll learn about the QRS complex and its measurement as a part of a review for nursing students, nurses, ACLS, NCLEX, and more. The QRS complex represents ventricular depolarization (leading to contraction of the ventricles). Atrial repolarization also occurs here, but it is not visible.

You may have seen more of PR interval in text books, because it is used for ECG interpretation. But you should be able to find PQ segment too. These are 2 different things. The PR interval measures from the start of P wave. So PR interval = P wave + PQ segment. To understand ECG, we intentionally use PQ segment as it represents one single event, easier to understand. The PR interval is used, however, to interpret ECG. You can see how to use PR interval to interpret ECG here (this is another one of our videos): 🤍 ©Alila Medical Media. All rights reserved. Support us on Patreon and get FREE downloads and other great rewards: patreon.com/AlilaMedicalMedia The cardiac conduction system consists of the following components: - The sinoatrial node, or SA node, located in the right atrium near the entrance of the superior vena cava. This is the natural pacemaker of the heart. It initiates all heartbeat and determines heart rate. Electrical impulses from the SA node spread throughout both atria and stimulate them to contract. - The atrioventricular node, or AV node, located on the other side of the right atrium, near the AV valve. The AV node serves as electrical gateway to the ventricles. It delays the passage of electrical impulses to the ventricles. This delay is to ensure that the atria have ejected all the blood into the ventricles before the ventricles contract. - The AV node receives signals from the SA node and passes them onto the atrioventricular bundle - AV bundle or bundle of His. - This bundle is then divided into right and left bundle branches which conduct the impulses toward the apex of the heart. The signals are then passed onto Purkinje (pur-KIN-jee) fibers, turning upward and spreading throughout the ventricular myocardium. Electrical activities of the heart can be recorded in the form of electrocardiogram, ECG or EKG. An ECG is a composite recording of all the action potentials produced by the nodes and the cells of the myocardium. Each wave or segment of the ECG corresponds to a certain event of the cardiac electrical cycle. When the atria are full of blood, the SA node fires, electrical signals spread throughout the atria and cause them to depolarize. This is represented by the P wave on the ECG. Atrial contraction , or atrial systole (SIS-toe-lee) starts about 100 mili-seconds after the P wave begins. The P-Q segment represents the time the signals travel from the SA node to the AV node. The QRS complex marks the firing of the AV node and represents ventricular depolarization: - Q wave corresponds to depolarization of the interventricular septum. - R wave is produced by depolarization of the main mass of the ventricles. - S wave represents the last phase of ventricular depolarization at the base of the heart. - Atrial repolarization also occurs during this time but the signal is obscured by the large QRS complex. The S-T segment reflects the plateau in the myocardial action potential. This is when the ventricles contract and pump blood. The T wave represents ventricular repolarization immediately before ventricular relaxation, or ventricular diastole (dy-ASS-toe-lee). The cycle repeats itself with every heartbeat.

EKG / ECG interpretation basics nursing NCLEX review made easy. What is the meaning of EKG or ECG? This stands for electrocardiogram, which assesses the electrical conduction system of the heart. EKG interpretation quiz: 🤍 NOTES: 🤍 As a nurse, you'll want to be familiar with basic ekg/ecg interpretations, how to identify heart rhythms, P waves, T waves, PR intervasl, QRS complexes, PR segments, ST segments, J point, QT intervals, and so forth. In this video, Nurse Sarah breaks down EKG basics and gives examples of how to measure different parts of a 6-second EKG strip. EKG/ECG strips contain small boxes that are found within larger boxes. These boxes represent units of time in seconds. Smaller boxes represent 0.04 seconds, whereas larger boxes represent 0.20 seconds.

Voltage (height) of the complexes. Spot diagnoses: Specific morphology patterns that are important to recognise. QRS Width Normal QRS width is 70-100 ms (a duration of 110 ms is sometimes observed in healthy subjects). The QRS width is useful in determining the origin of each QRS complex (e.g. sinus, atrial, junctional or ventricular). Narrow complexes (QRS less than 100 ms) are supraventricular in origin. Broad complexes (QRS greater than 100 ms) may be either ventricular in origin, or due to aberrant conduction of supraventricular complexes (e.g. due to bundle branch block, hyperkalaemia or sodium-channel blockade). Narrow QRS Complex Morphology - Narrow (supraventricular) complexes arise from three main places: Sino-atrial node (= normal P wave) Atria (= abnormal P wave / flutter wave / fibrillatory wave) AV node / junction (= either no P wave or an abnormal P wave with a PR interval less than 120 ms) Broad QRS Complex Morphology - Broad/Wide QRS Complexes A QRS duration greater than 100 ms is abnormal A QRS duration greater than 120 ms is required for the diagnosis of bundle branch block or ventricular rhythm Broad complexes may be ventricular in origin or due to aberrant conduction secondary to: Bundle branch block (RBBB or LBBB) Hyperkalaemia Poisoning with sodium-channel blocking agents (e.g. tricyclic antidepressants) Pre-excitation (i.e. Wolff-Parkinson-White syndrome) Ventricular pacing Hypothermia Intermittent aberrancy (e.g. rate-related aberrancy) #qrscomplex #qrswave #qrsecg #ecgyoutube #ecgbasics #ecgcourse #ecgmadeeasy #ecgphysiology #ecgonline #completeecgcourse #ecginterpretation #narrowqrs #wideqrs #qrs #abnormalqrs #qrsduration

Always seek the advice of a qualified healthcare provider with any questions you may have regarding a medical condition. Cardiac axis is the net direction of electrical activity during depolarization. In a healthy heart, the net movement is downward and slightly left. This axis is altered, or deviated, in certain conditions. For example, in left ventricular hypertrophy the axis is skewed further left; while right ventricular hypertrophy results in a deviation to the right. Cardiac axis can be determined by examining the 6 limb leads, which look at the heart from different angles in a vertical plane. The QRS axis is the most important, and also the easiest to be determined, as it represents ventricular depolarization. The QRS axis is considered normal when it is between -30 and +90 degrees. Left axis deviation is between -30 and -90 degrees. Right axis deviation goes between +90 and +180 degrees. The rest is known as northwest axis or extreme axis deviation. Remember that depolarization TOWARD a lead produces a POSITIVE deflection; depolarization AWAY from a lead gives a NEGATIVE deflection. Impulses moving at a 90 degree angle relative to a lead produce an isoelectric, or equiphasic result with positive and negative deflections of similar amplitude. There are several methods to estimate the QRS axis; we here discuss 2 of them. The quadrant method. This method looks at the QRS complex in lead 1 and lead aVF. If the QRS complex is mostly positive in both leads, the axis is somewhere in between the 2 leads, which is in the normal range. If it’s negative in lead I and positive in aVF, the axis is running away from lead I but toward aVF and is thus in the lower right quadrant. The diagnosis is right axis deviation. A positive value in lead I and negative in lead aVF, place the axis in the upper left quadrant, which interprets as possible left axis deviation. A more accurate method will be needed to further determine if it is borderline normal or left deviation. Negative values of the QRS complex in both leads are indicative of extreme axis deviation. The isoelectric lead method: this method consists of finding the isoelectric or equiphasic lead – the one with equal, or closest to equal, negative and positive deflections. In other words, the one with zero, or nearest to zero, net amplitude. The axis line is perpendicular to the direction of the isoelectric lead. Next, look at the lead that runs nearest to this line. If the QRS complex is positive in that lead, the axis points to roughly the same direction as the lead. If it is negative, the axis points to the opposite direction.

The “QRS complex” is the combination of the Q wave, R wave and S wave and represents ventricular depolarization. This term can be confusing since not all ECG leads contain all three of these waves, yet a “QRS complex” is said to be present regardless. For example, the normal QRS complex in lead V1 does not contain a Q wave, but only a R wave and S wave, yet the combination of the R wave and S wave is still referred to as the QRS complex for this lead. - Watch ECG The P Wave HD.......🤍 Watch ECG P-R Interval HD.......🤍 Watch ECG QRS complex HD......🤍 Watch ECG The T Wave HD........🤍 Watch ECG The U wave HD ......🤍 - SUBSCRIBE and LIKE ...... 🤍 Best Medical Books Link Below - 🤍 Best Medical Instrument Link Below - 🤍 Find us on Facebook : 🤍 🤍 🤍 Join Our Forum: 🤍

This lesson covers the Wide QRS complex, the second of two divisions for pediatric tachyarrhythmias. Wide QRS complex involves only two tachycardias, ventricular and unusual SVT. Each is explained along with identifying signs and characteristics. "Wide QRS complex tachycardias include ventricular tachycardia and unusual SVT. Ventricular tachycardia (or VT) is uncommon in children but can be rapidly fatal. Unless the individual has a documented wide complex tachyarrhythmia, an ECG with a QRS complex greater than 0.09 seconds is VT until proven otherwise. Polymorphic VT, Torsades de pointes, and unusual SVT (SVT with wide complexes due to aberrant conduction) may be reversible, for example, magnesium for Torsades, but do not delay treatment for VT. Any of these rhythms can devolve into ventricular fibrillation (VF). VT may not be particularly rapid (simply greater than 120 bpm) but is regular. Generally, P waves are lost during VT or become dissociated from the QRS complex. Fusion beats are a sign of VT and are produced when both a supraventricular and ventricular impulse combine to produce a hybrid appearing QRS (or fusion beat)."

This lesson covers the Narrow QRS Complex, one of two divisions for pediatric tachyarrhythmias. The tachycardias which are classified as Narrow QRS are introduced. Their relevance to PALS providers and the likeliness of encountering each is also explained. "Narrow QRS complex tachycardias include atrial flutter, sinus tachycardia, and supraventricular tachycardia (or SVT). Atrial flutter is an uncommon rhythm distinguished on an ECG as a sawtooth pattern. It is caused by an abnormal reentrant pathway that causes the atria to beat very quickly and ineffectively. Atrial contractions may exceed 300 bpm but not all of these will reach the AV node and cause a ventricular contraction. Most often, as a PALS provider, you will have to distinguish between two similar narrow QRS complex tachyarrhythmias: sinus tachycardia and supraventricular tachycardia (SVT). SVT is more commonly caused by accessory pathway reentry, AV node reentry, and ectopic atrial focus. For details and differences between sinus tachycardia and SVT, please refer to Table 17 in your corresponding PALS manual."

Clinical Cousins discuss QRS Complex and Chest Lead Progression
In lecture will apply the knowledge of cardiac vector and vectorial analysis to understand the formation and recording of normal ECG and QRS complex.
What is the QRS complex? What makes it normal? What makes it wide?
If we see a widened QRS complex, it could mean either thing: it could mean a supraventricular tachycardia (an impulse originating above the ventricles) WITH a defective conduction system... Or it could mean an impulse originating from the ventricles - a ventricular tachycardia. However, if we see a narrow QRS complex, then we know the impulse is originating above the ventricles AND the heart conduction system is intact! So, if we see a narrow QRS complex, we know we are looking at a supraventricular tachycardia! Check out the full 8-min video: 🤍
