If you're looking for information on how to use an older model of an ECG device, here are some general steps that might be helpful: Clinical correlation required
An electrocardiogram (ECG) is a primary tool for identifying a past heart attack, often referred to as an "old MI" (Myocardial Infarction). When heart tissue dies due to lack of oxygen, it is eventually replaced by non-conductive scar tissue. This "electrically silent" scar permanently alters the heart’s electrical pathways, leaving distinct "markers" on an ECG tracing. Primary Findings of an Old MI Primary Findings of an Old MI It is
It is usually > 1 mm deep or more than 25% of the height of the succeeding R wave.
