👉 Myronic is a term that describes a condition where an individual's heart muscle cells are not able to contract effectively, causing the heart to beat more slowly than usual. This can lead to a variety of symptoms, including shortness of breath, fatigue, and discomfort in the chest or arms. Myocardial infarction, which occurs when blood clots form in the coronary arteries that supply the heart muscle cells, is often associated with myronic conditions.
