CONDUCTION SYSTEM ANATOMY. The functions of the electrical system of the heart (Fig. II-1) are not only initiation and rate of the heartbeat, but its coordinated transmission to the entire heart resulting in maximum mechanical efficiency.
Chapter 1 The Electrical Activity of the Heart. Basic concepts. The heart is a pump that sends blood to every organ in the human body. This is carried out through an electrical stimulus that originates in the sinus node and is transmit-ted through the specific conduction system (SCS) to contractile cells.
24 Σεπ 2024 · Your heart rhythm is the way your heart beats. Conduction is how electrical impulses travel through your heart, which causes it to beat. Some conduction disorders can cause arrhythmias, or irregular heartbeats. Three common conduction disorders are: Bundle branch block; Heart block; Long QT Syndrome; Bundle branch block
7 Απρ 2017 · As electrical integrity is essential for a well-functioning heart, innovative strategies have been bioengineered to improve heart conduction and/or promote myocardial repair, based on: (1)...
17 Αυγ 2023 · The cardiac conduction system is a network of specialized cardiac muscle cells that initiate and transmit the electrical impulses responsible for the coordinated contractions of each cardiac cycle.
12 Μαρ 2023 · The electrical system of the heart is critical to how it functions. It controls the electrical impulses that cause your heart to beat and their conduction, which organizes the beating of your heart. The movement of electrical signals across the heart is what is traced on an electrocardiogram (EKG). The EKG is also what allows irregularities in ...
HEART ELECTRICAL ACTIVTY. Emma Jakoi, Ph.D. LEARNING OBJECTIVES. Describe the conduction system of the heart. Explain spontaneous electrical activity (pacemaker) in cardiac muscle. Explain action potentials of ventricular cardiac muscle. Explain the cardiac conduction system, pacemakers, and regulation of heart rate by the autonomic nervous system.
