1. Some people with bundle branch blocks are born with this condition. 2. This is known as appropriate T wave discordance with bundle branch block . 3. This condition is known as a bundle branch block . 4. They produce QRS complexes of relatively short durations with a right bundle branch block pattern. 5. In most cases right bundle branch block has a pathological cause though it is also seen in healthy individuals. 6. The most commonly seen signs in the ECG are sinus tachycardia, right axis deviation, and right bundle branch block . 7. Evidence of this phenomenon may rarely include ECG patterns characteristic of certain types of heart block such as Left bundle branch block . 8. During a right bundle branch block , the right ventricle is not directly activated by impulses travelling through the right bundle branch. 9. 1 ) A new electrocardiographic classification of incomplete branch block with the discovery of 2 new types of bundle branch block in 1948 10. It is seen in conditions that delay left ventricular emptying ( e . g ., aortic stenosis, left bundle branch block ).
