ECG Features of Left Ventricular Hypertrophy
an increase in the depth of the S wave in leads V1 and V2 and,
an increase in the height of the R wave in leads V5 and V6.
The genesis of ECG
Right Bundle Branch Block (RBBB)
Right Bundle Branch Block or RBBB is a delay or block of conduction within the right bundle branch. In complete RBBB, the duration of QRS is >120ms and in incomplete RBBB it is between 100 and 120ms.
ECG in Right Ventricular Hypertrophy
Electrocardiographic Features of Right Ventricular Hypertrophy (RVH) Right Ventricular Hypertrophy results in the generation of increased QRS forces that are basically directed anteriorly and to the right. Features of ECG in Right Ventricular Hypertrophy will be covered in this article. ECG in Right Ventricular Hypertrophy may indicate involvement one or more of three major regions- …
Basic Principles of ECG
Basic Principles of ECG- P Wave Basic principles of ECG are very important to learn in order to begin reading ECG. No matter how complicated or tough an ECG is, most difficult ECGs can be cracked if one understands the basic principles of ECG. P Wave Overview The P wave is the first positive deflection …
Left Bundle Branch Block (LBBB)
LBBB ECG :- Left Bundle Branch Block or LBBB is the result of a delay or interruption of conduction within the left bundle branch. In complete LBBB, the duration of QRS is >120ms and in incomplete LBBB it is between 100 and 120 ms. Complete LBBB ECG features :- Prolonged QRS duration >120ms and may …
Right Bundle Branch Block (RBBB)
Right Bundle Branch Block is a delay or block of conduction within the right bundle branch. In complete RBBB, the duration of QRS is >120ms and in incomplete RBBB it is between 100 and 120ms. Complete RBBB: The ECG Criteria is as follows:- QRS duration >120ms rsR pattern in lead V1 with R’ >r Slurred …
ECG Axis Interpretation
ECG Axis Interpretation Axis interpretation using the schematic illustration demonstrates the relationship between QRS axis and the frontal leads of the ECG. Normal Axis = QRS axis between -30° and +90°.Left Axis Deviation = QRS axis less than -30°.Right Axis Deviation = QRS axis greater than +90°.Extreme Axis Deviation = QRS axis between -90° and …
