Flashcards in Cvd Deck (11):
What is the pq segment?
Impulse arrives at AV node and is transmitted through bundle of His and left and right bundle branches to pukinje fibres.
AV vas hat is QRS complex
AV valve close
Purkinje fibres transmit impulse to ventricular myocardium which causes ventricular contraction, pumping blood through semilunar valves which open
What is the t wave?
Ventricles repolarise and prepare for the next contraction.
AV valves open
What does the straight line on an ECG mean?
No electrical activity
Atria fill from vena cava and blood begins to flow through AV valves into ventricles
What are you at risk of if your have CvD?
How to manage high blood pressure?
