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

13 Οκτ 2023 · The heart's electrical signals start in a group of cells at the top of the heart called the sinus node. They pass through a pathway between the upper and lower heart chambers called the atrioventricular (AV) node. The movement of the signals causes the heart to squeeze and pump blood.
19 Απρ 2023 · The initial electrical impulse that begins the process of a heartbeat is generated by a group of cells located in the upper chamber of the heart, the atrium. These cells act as an automatic pacemaker, starting the electric signal that spreads along the "wiring" within the heart muscle, allowing a coordinated squeeze so that the pump can function.
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 rhythm problems happen when there's a fault with the electrical system that makes your heart beat. This can be the result of a heart rhythm condition, such as atrial fibrillation or supraventricular tachycardia (SVT).
2 Φεβ 2022 · An arrhythmia is a disturbance in the rhythm of the heartbeat, whether it’s beating too hard, too fast—or skipping beats. This condition can be caused by problems with the heart’s electrical system.
The electrical current that begins each heartbeat originates in the heart’s pacemaker (called the sinus node or sinoatrial node), located in the top of the upper right heart chamber (right atrium). The rate at which the pacemaker discharges the electrical current determines the heart rate.
