Risk of Lidocaine With Incomplete Right Bundle Branch Block?

I was planning to have liposuction surgery, its under local and without sedation it is 90 minutes with is less, it is a revision to a prior one which left me with a deformity, when i did my ecg the machine diagnosed me with incomplete right bundle branch block, then the doctor checked and said i was fine, i also met a cardiologist who said after echo and stress its minor i read that lidocaine is a contraindication to a block online, is that true and should i go ahead? is it high risk?
