Really well presented. Good summary points. Well done
Amazing approach. Easy to remember now.
Great presentation. One additional point that I've found helpful over time: in the few patients that I've seen who turned out to have idiopathic pericarditis, most noted that the characteristic chest pain that you described was decreased by leaning forward (into the position where it is easiest to auscultate for the friction rub).
..which I heard you mention in the last part of your presentation (~21.00)....:-)
What you do matters.
