In brief: Sometimes
A left bundle branch block is a finding on an EKG ( the electrical tracing of your heart.
) it shows that something has altered the way your heart conducts electrical impulses. Chemotherapy can do it, but so can heart disease. Your doctor should rule out other causes for a left bundle branch block before assuming chemotherapy is the cause.

In brief: Chemo
Many chemotherapies can cause heart problems (ie, adriamycin (doxorubicin) - heart muscle problems; Paclitaxel - very fast heart rate or arrhythmia).
Lbbb is not a common side effect but it is possible.
