This CCS is responsible for muscle contractions, ensuring consistent rhythmic beating of the atria and ventricles to facilitate blood circulation.[7, 8] While CA can arise due to multiple causes like electrolyte imbalances, medications, etc., the two major causes are disruption in the CCS by myocardial infarction (MI) and/or dysregulation of ion channel subunits. This evidence concerns the gene CCS and myocardial infarction.
