conduction system and how it works

  • electrical impulses travel through the heart pathway known as the conduction system

  • you need an electrical stimulus for a mechanical contraction

  • electric comes first

  • ECG is evidence of electrical activity, not contraction

ECG tracing conduction system

  • it is a rapid highway system designed to spread the impulse quickly

  • think h”highway system with no traffic”

what is a 12 lead ECG/EKG

  • Helps to identify cardiac issues

  • comeplete view of the hearts electrical activity

  • heps to identity angina and MI

  • Helps to identity pericarditis, electrolytes imbalances

  • Meds

  • The waveforms on the ECG/EKG represent elecgrical activity produced by the movement of ions across the membrane

  • representing depolarization and repolarization
