The rSr’ pattern can be considered a normal variant due to delay in the activation of the basal part of the right ventricle (RV). It has been reported that an rSr’ pattern is a common finding in the general population.
What causes RSR pattern in RBBB?
Differential Diagnosis of RBBB An RSR’ pattern in V1-3 may also be caused by Brugada syndrome — an ECG pattern associated with malignant ventricular arrhythmias.
What is RBBB morphology?
The QRS morphology criteria to diagnose VT with a RBBB include the following: A monophasic R or biphasic qR complex in V1. An RSR’ or “bunny ear” pattern present in V1 or V2, with the R peak higher in amplitude than the R’ peak (see image below) A rS complex in lead V6 (favors VT)
How do you tell VT from sbert with Aberrancy?
Monomorphic VT Although there is a broad complex tachycardia (HR > 100, QRS > 120), the appearance in V1 is more suggestive of SVT with aberrancy, given that the the complexes are not that broad (< 160 ms) and the right rabbit ear is taller than the left.
What does rSr pattern in V1 mean?
Incomplete right bundle branch block (RBBB) and complete RBBB are common normal ECG variants in the young. The ECG under consideration demonstrates an incomplete right bundle branch block (RBBB) that is an rSr ‘pattern’ in lead V1 with a normal qrs duration (less than 0.12s, less than 3 small squares).
What is an rSr complex?
The abnormal RSR’ complex arises from a terminal conduction delay (dissimilar to either RBBB or LBBB using the vectorcardiogram) of left ventricular (LV) depolarization within impaired tissue surrounding the infarct scar.
What causes rSR?
We often face this finding in asymptomatic and otherwise healthy individuals and the causes may vary from benign nonpathological variants to severe or life-threatening heart diseases, such as Brugada syndrome or arrhythmogenic right ventricular dysplasia.
What is Aberrancy in ECG?
Aberrant ventricular conduction is a common electrocardiographic (EKG) manifestation that occurs when the supraventricular electrical impulse is conducted abnormally through the ventricular conducting system. This results in a wide QRS complex that may be confused with a ventricular ectopic beat.
What is AFIB with Aberrancy?
Atrial tachycardia with aberrant conduction When atrial fibrillation occurs with aberrant conduction and a rapid ventricular response, a totally irregular broad complex tachycardia is produced.
What is supraventricular tachycardia with Aberrancy?
Any tachycardic rhythm with a left or right bundle branch block that is NOT ventricular tachycardia is considered “supraventricular tachycardia with aberrancy”.
What does RSR mean?
RSR

| RSR | Retail Sales Representative |
| RSR | Rail Safety Regulator (various locations) |
| RSR | Regular Supervisory Report (finance) |
| RSR | Really Simple Reporting (Akvo) |
How to calculate RR L rotation in AVL tree?
R L rotation = LL rotation + RR rotation, i.e., first LL rotation is performed on subtree and then RR rotation is performed on full tree, by full tree we mean the first node from the path of inserted node whose balance factor is other than -1, 0, or 1. Q: Construct an AVL tree having the following elements H, I, J, B, A, E, C, F, D, G, K, L 1.
How do you insert an AVL tree in aavl?
AVL Tree | Set 1 (Insertion) 1 Perform the normal BST insertion. 2 The current node must be one of the ancestors of the newly inserted node. Update the height of the current node. 3 Get the balance factor (left subtree height – right subtree height) of the current node.
What is the balance factor of AVL tree?
AVL tree permits difference (balance factor) to be only 1. If the difference in the height of left and right sub-trees is more than 1, the tree is balanced using some rotation techniques. To balance itself, an AVL tree may perform the following four kinds of rotations −
What is avavl tree?
AVL tree is a self-balancing Binary Search Tree (BST) where the difference between heights of left and right subtrees cannot be more than one for all nodes.
