Descriptions:
Inbound Relationships | Type | Active | Source | Characteristic | Refinability | Group |
Electrocardiogram: left posterior fascicular block | Is a | False | ECG: left bundle branch block | Inferred relationship | Some | |
Electrocardiogram: left anterior fascicular block | Is a | False | ECG: left bundle branch block | Inferred relationship | Some | |
Electrocardiographic complete left bundle branch block (finding) | Is a | True | ECG: left bundle branch block | Inferred relationship | Some | |
Left anterior fascicular block is characterized by all of the following: Left-axis deviation with frontal QRS axis between 45° and 90°; Q wave in lead aVL; rS in inferior leads; QRS duration is 120 ms. | Is a | True | ECG: left bundle branch block | Inferred relationship | Some | |
Right-axis deviation with frontal QRS axis between 90° and 180° rS in leads I and aVL and qR in inferior leads (Q waves 40 ms); QRS duration 120 ms; Exclude other causes of right-axis deviation. | Is a | True | ECG: left bundle branch block | Inferred relationship | Some |
