Is it serious?

‘You are more likely to have symptoms if you have other problems in addition to your left bundle branch block.’ – https://www.cedars-sinai.org/health-library/diseases-and-conditions/l/left-bundle-branch-block.html

Because of the risk of this, if this is new we are likely to advise you to attend hospital. We may advise you to attend a specialist cardiac hospital, depending on your symptoms and other signs of illness that you might have called us for. If you already know you have the condition, it is worth noting it down and keeping a copy of your ECG trace for any future queries.

If you are a healthcare professional and you are reading this, please let us know what you think by commenting or getting in touch. Would you use this to explain the condition to your patients?
