Tracing of the Week (Tracing #240)

	A.....LBBB
	B.....RBBB
	C.....LAFB
	D.....LVH(Tall R-wave in Lead aVL)
	E.....Tall R-wave in Lead aVL is probably secondary to LAFB (hence this is probably a pseudo-LVH )

	F.....This is a classic bifascicular block(RBBB + LAFB) and the patient will most likely develop complete heart block. You should notify the cardiologist and prepare for external pacing.This decision would be based on ECG interpretation alone.
	G.....Electrical axis = exactly -30 degrees
	H.....B,C,and E only. The finding of a bifascicular block is common(and is most often benign) and per se does not require cardiology intervention.You should simply recommend clinical correlation and comparison with the old tracing.
	I.......B,C, D and G only.
	See Dr. Stanley's HEART rule for the classic criteria of LAFB, LBBB, RBBB, LVH
