    Isovolumetric* .... LOL I really cannot spell. Also to be perfectly clear, EF = [(SV/EDV)*100]

    A visual trick: The 'C' in increased Contractility reminds you the P/V loop shifts left. The 'A' in increased Afterload reminds you the P/V loop narrows and points up (pressure increases). The 'P' in increased Preload reminds you the P/V loop shifts right.

    I can honestly say these videos are the highlight of my Step 1 studying!! Since isovolumetrics require all valves to be closed --> mitral/aortic regurgitation completely lose isovolumetric shape (also increased EDV b/c extra blood, incr SV) - regurgitation is a BLOB of blood so shape is a BLOB Aortic stenosis --> increased aortic pressure --> increased afterload shape Mitral stenosis --> impacts diastolic filling --> decreased EDV bc impaired filling, decr SV, decr ESV (mitraL - L shift)

    I literally had stopped reading heart physiology 2 months back when I read PV Loops lol (thanks to the graphs) and started reading another subject for step 1 and decided that I’ll tackle that topic later on. Little did I know that you’ll make such a fantastic video on this topic. Today, I’m delighted to announce that I shall resume reading cardiology, all thanks to this video. 😁 Thank you for all the additional free points I’ll score on the exam with your help.

    hi, long time fan, one time patreon here)) why only stroke volume change ie NO change EDV or EF w/ increase preload? in contractility explaination u said ESV go down and sooo EF go up.. but on preload graph it show only SV change(increase) ?? EDV point was shift right to higher volume,, and should be also change EF?? cheers dude! :))
