Hello -- The findings of your father's cardiological workup, if they were not triggered by frank heart disease or possible heart disease symptoms, are unremarkable. The echocardiogram findings are not very informative of anything significant at all.
The EKG shows some non-specific signs which may be seen in the setting of acute of occult heart disease, but also often show up in totally healthy people as well. When there is a left anterior fasicular block there will be a corresponding left deviation of the axis of the QRS complex in the EKG, but again, if no underlying heart disease is found this has no meaning nor significance. The same is true for low voltage, which can occur for a number of reasons, including excess body fat, electrolyte imbalance, and other even less important causes.
Given there is no history of prior heart disease in your father, it is very likely there is nothing else to be concerned about. If appropriate study of these findings and others show no evident disease then they are just findings that are not textbook-normal and so must be noted for the record, as many of us have slightly abnormal EKGs and this needs to be known when future EKGs are done in order to quickly compare and rule out any problem.
Hope this is helpful. Good luck to you. Please follow up with us here as needed.
