Final answer:
An electrocardiogram (ECG) is created from the electrical impulses generated by the heart as it pumps. The heart's internal pacemaker regulates the electrical signals and mechanical actions in the heart. A graphic pattern is produced by the depolarization and repolarization of the heart's muscle cells.
Step-by-step explanation:
The process by which a graphic pattern is created from the electrical impulses generated in the heart as it pumps is known as an electrocardiogram (ECG). An ECG is a recording of the electrical impulses of the cardiac muscle. The electrical signals and mechanical actions in the heart are regulated by the heart's internal pacemaker, which starts at the sinoatrial (SA) node and spreads through the atria, atrioventricular (AV) node, bundle of His, bundle branches, and Purkinje fibers before causing the ventricles to contract.
