Hello and thank you for using HCM.I carefully read your question and I understand your concern. I will try to explain you something and give you my opinion. You should know that the electrocardiogram apparat gives an automatic interpretation based on the amplitudes and impulse.But we never judge on a cardiac hystori based on paper interpretation but on the cardiologyst interpretation, meaning that the electrocardiogram should be interpreted by the doctor, not the machine. So, left axis deviation is not something to worry about.It is a normal ecg pattern in people suffering from hypertension. About infarct diagnosis, it is not made only by tje electrocardiogram.To make tje diagnose of infarction we rely on different characteristics like chest pain, electrocardiogram, cardiac enzymes and echo cardiograhy. If your doctor saod that you had this changes, it might mean that this is not an infarction but just a electrocardiogram pattern. So, to definitely make the diagnosis I wold recomend a cardiac echo to evaluate heart walls if it is a problem or not, carfiac enzymes and to talk this whith your cardiologyst. Hope I was helpfull. Best regards, Dr.Ervina.
