Adenosine : Class: Antidysrhythmic Indications= Cardiac dysthymia 1. SVT- narrow complex: HR over 150 bpm adult, over 180 bpm child, over 220 bpm for infants; unresponsive valsalva & 2. Reg/monomorphic wide complex tachycardia w/ adequate perfusion or alert patient with poor perfusion MOA= slows conduction through AV node, interrupts AV reentry pathways as well as conduction through SA nodes Adult= 6 or 12 mg rapid IVP, waiting (1-3 seconds), followed by 10ml of NS IF no conver...

2nd degree block type II - Correct Answer-ECG strip that shows regular atrial rhythm, an atrial rate greater than ventricular rate (some QRS complexes are dropped) and a constant PR interval when the atrial and ventricular complexes appear together would most likely be identified as what rhythm? The ventricles are being stimulated during the relative refractory period - Correct Answer-Why is the R-on-T premature ventricular complex (PVC) of major concern? B. Multifocal premature ventricula...

1st degree AV Nodal Block - the AV node is having difficulty getting the action potentials on through to the rest of the conduction system. See prolonged PR intervals 2nd degree AV Nodal Block - there is even more difficulty than in first degree. 3rd degree AV Nodal Block - even more serious than second degree. See many Ps without QRS complexes, AP not getting through at all A bands - contain mainly thick filaments Abstract memory - Type of Explicit memory, Fact memory ( learning facts, li...

What is a positive stress test Correct Answer-Flat or Down sloping St-segment depression >1 mm occurring 80 msec after j point When to stop a stress test Correct Answer-St segment depression > 2 mm, ventricular tachycardia, drop in SBP > 15, chest pain, dyspnea, lightheadedness Stress test of choice with a LBBB or ventricular pacing? Correct Answer-Myocardial perfusion imaging with adenosine,NOT exercising! Know the algorithm for stress testing Correct Answer-See page 5-3,figur...

PAEA Emergency Medicine EOR Exam Study Guide. what is the most common cause of heart failure? specifically left sided? right sided? - - MC is CAD (coronary artery disease) -L sided: *CAD* & HTN -R sided: *L sided HF* & pulmonary dz decreased ejection fraction, thin ventricular walls, dilated LV chamber, and an S3 gallop (filling of dilated ventricle) is associated with systolic or diastolic heart failure? - systolic (MC form of CHF) *(the sound is actually heard in the diastole though) ...
