Because the Tawara conduction system has one right and two left branches, it is referred to as a trifascicular system, that is to say a system with three lanes of conduction. If these three lanes are all blocked, this is considered a trifascicular block (extremely dangerous). In addition, two other scenarios are considered trifascicular blocks: a first degree AV block in combination with a right bundle branch block (RBBB) and a left anterior hemiblock and first degree AV block in combination with a RBBB and a left posterior hemiblock.
