Right ventricular infarction (RVI) lead changes correct answersII, III, AVF R ventricular infarction s/s correct answersclear breath sounds, hypotension, JVD. R ventricular dilation and dec contractility dec preload and CO Reperfusion therapy standard correct answersWithin 60 min of ED arrival Common causes of PEA correct answersHypoxia, tension pneumo, cardiac tamponade BNP as a marker correct answersof L ventricular dysfunction bc ventricles make BNP and an inc of over 100 pg/ml indicates symptomatic HF Transcutaneous pacing (TCP) correct answersA beat after every pacer spike is electrical capture. Beats are wide complex bc ventricle is paced. Palpate central pulse, pt may still be hypotensive w/ diminished or absent peripheral pulses. Preferred tx with symptomatic brady esp in pts with acute MI Wolff Parkinson-White (WPW) syndrome correct answersshortened PR interval and widened QRS complex with a delta wave. When there is an extra electrical conduction path to heart causing electrical signal to arrive too soon at ventricle (pt presents in tachy) Brugada syndrome correct answersR bundle branch block with ST segment elevation in leads V1-V3 and inc risk of sudden cardiac death (SUDS), common in young men Wellen syndrome correct answersT wave changes plus history of anginal chest pain w/o serum marker abnormalities, EKG lacks Q waves and significant ST segment elevation. Assoc with critical proximal L anterior descending (LAD) artery stenosis
