cardiac conduction
Heart's electrical pathway
Cardiac conduction is the electrical system that coordinates the heartbeat, transmitting impulses from the sinoatrial node through specialized tissue to trigger rhythmic contractions.
When doctors discuss cardiac conduction, they're examining how well these electrical signals propagate through the heart chambers.
Abnormalities in cardiac conduction—such as blocks or arrhythmias—can cause the heart to beat too fast, too slow, or irregularly.
The ECG revealed a cardiac conduction defect.
