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.

Basic Principles of ECG

This is an article about the basic principles of ECG which include normal and abnormal P wave, QRS complex, T wave and U waves. I hope you’ll enjoy reading this article. It is printed on grid paper called the ECG strip or ECG tracing. The process of producing an electrocardiogram is termed electrocardiography. It is a non-invasive medical procedure performed by recording the cardiac impulses on the surface of our body using specialized electrodes over specific regions of our body. Basic Principles of ECG- P Wave P wave Overview: The P wave is the first positive deflection on the ECG and … Read more

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 :- Significance of complete LBBB- Incomplete Left Bundle branch Block- In the case of incomplete LBBB, conduction through the left bundle branch and its ramifications is still possible but will be delayed. This is in cintrast to complete LBBB where conduction through the left sided specialised conduction system is no longer … Read more
