In brief: Abnormal conduction

The signal to beat is distributed to through the heart by a specialized electrical system. The right bundle is one of the branches of this system. If conduction through the right bundle is slowed or blocked the parts of the heart it serves will contract late, seen as widening of the electrocardiographic qrs-wave.
Unless the remainder of the conduction system fails, it usually isn't a problem.
