I'm 28 and recently got a job at a refinery. During my medical checkup, they found something called Left Anterior Hemi Block in my ECG. I'm a bit concerned since my health history has always been good. Everything else like my BP, sugar levels, eyes, ears, and chest X-rays came out normal. Should I be worried about this, or is it not that serious?

Left Anterior Hemiblock (LAH) is a conductive abnormality in the heart's electrical system, which often does not cause symptoms and is not necessarily dangerous. It can be more significant in the presence of other heart conditions, but in many cases, it's a mild and isolated finding. It's essential to consult a cardiologist for further evaluation and to ensure that no underlying heart disease is contributing to the condition.
