Trifascicular Block Beat - (BBTI)
Definition
Section titled “Definition”A block of all three fascicles (both bundle branches and one fascicle of the left bundle). Not used here for coding.
Criteria (not used)
Section titled “Criteria (not used)”-
QRS >120 ms.
-
Different P-Q intervals (R-R identical, P-P identical).
-
Often diagnosed if there are nearby beats with bifascicular block.
Priority
Section titled “Priority”The priority of the annotation is determined by the severity of the event.
| Priority | Highest | High | Medium | Low | Lowest |
|---|---|---|---|---|---|
| Continuous | - | - | 1 | - | - |
| Per Minute | - | - | - | - | - |
| Per Hour | - | - | - | - | - |
| Per 24 Hours | - | - | 500 | - | - |
Compatibility
