Quiz - Giddy up

Dive into the essentials of cardiac physiology with this interactive quiz focusing on intrinsic rates of heart nodes such as the SA node and AV node, as well as the ventricles. Explore different cardiac rhythms based on P-waves, R-to-R intervals, and conduction system pathways. Learn the order of the heart's conduction system, the process of depolarization in cardiac cells, and the effects of various chronotropic and dromotropic agents. Test your knowledge of Frank-Starling's Law and engage with visual aids like Einthoven's Triangle.

Presentation Transcript

  1. Quiz - Giddy up What – I did not know about this

  2. What is the intrinsic rate of the following: • SA node • AV node • Ventricles

  3. If you have a rhythm that has an irregular R to R; P wave that is upright, uniform and one-for –one; PRI <0.20sec, and QRS <0.12sec.What rhythm is it?

  4. A rhythm with no P wave and a regular R-to-R originates from what pacemaker site?

  5. List the order of the conductive system of the heart.

  6. Describe the steps of the depolarization of the cardiac cells – i.e. what do the electrolytes do, and in what order, to cause the heart to contract.

  7. Cardiac output equals what times what.

  8. Chronotropic agonist will do what?An Inotropic antagonist will do what?A Dromotropic agonist will do what?

  9. What is Frank Strarling’s Law (or effect) on the heart

  10. Draw Einthoven’s Triangle and please label all the leads and polarity.
