Car Talk
The most astute diagnosticians I encounter on a regular (weekly) basis are "Click and Clack, the Tappitt brothers", on NPR. They are immediately assessing every variable for any possible cause the moment they begin talking to a person with a car problem. They are insightful and compassionate about the foibles of people. They know their shit about cars. And they are funny. Every time someone tells me that they just can't stand Car Talk, I start wondering what their issue is with Italians, or with automobiles, or WHAT?
HEMIBLOCKS ON EKG
may look like axis shift
normal: leads 1, 2, 3, AVF all above baseline
left deviation: neg in AVF, 2, 3
right deviation: QRS neg in lead 1, pos in AVR
HYPERTROPHY ON EKG
right atrial: P waves in 2, 3, AVF larger than 2.5mm
left atrial: notched P wave in any lead, 2 peaks >0.04mm apart, P wave neg in V1 over 1mm
left ventricle: notched P wave??????? better look that up
right ventricle: tallest R wave at V1 (instead of V5 normal)
