**ECG** Flashcards
What does the “P Wave” represent?
Atrial Depolarization
what does the “PRI” represents?
- conduction thru atria.
- Beginning of P wave to start QRS
what do “ T Waves” represents?
Ventricle Re-polarization
what does “QRS” represent?
Ventricular depolarization
What is “ Hyperkalemia” ?
High Potassium
