Even though it usually does not progress to higher forms of heart block, it may require outpatient follow-up and monitoring of the ECG, especially if there is a comorbid bundle branch block.
22.
If the ECG confirms changes suggestive of myocardial infarction ( ST elevations in specific leads, a new left bundle branch block or a true posterior MI pattern ), thrombolytics may be administered or coronary arteries.
23.
Some authors consider left bundle branch block ( LBBB ) to be a technical bifascicular block, since the block occurs above the bifurcation of the left anterior and left posterior fascicles of the left bundle branch.
24.
Pharmacologic agents such as Adenosine, Lexiscan ( Regadenoson ), or dipyridamole is generally used when a patient cannot achieve adequate work level with treadmill exercise, or has poorly controlled hypertension or left bundle branch block.
25.
This is especially problematic in people with left bundle branch block ( blockage of one of the two primary conducting fiber bundles that originate at the base of the heart and carries depolarizing impulses to the left ventricle ).
26.
Right ventricular outflow tract ( RVOT ) tachycardia is the most common VT seen in individuals with ARVD . In this case, the EKG shows a left bundle branch block ( LBBB ) morphology with an inferior axis.
27.
"' Left anterior fascicular block "'( LAFB ) is an abnormal condition of the left ventricle of the heart, related to, but distinguished from, left bundle branch block ( LBBB ).
28.
Most commonly, it refers to a combination of right bundle branch block ( RBBB ) and either left anterior fascicular block ( LAFB ) or left posterior fascicular block ( LPFB ), with the former being more common.
29.
An electrocardiogram ( ECG / EKG ) may be used to identify arrhythmias, ischemic heart disease, right and left ventricular hypertrophy, and presence of conduction delay or abnormalities ( e . g . left bundle branch block ).
30.
In the Brugada syndrome, changes may be found in the resting ECG with evidence of right bundle branch block ( RBBB ) and ST elevation in the chest leads V1-V3, with an underlying propensity to sudden cardiac death.
