SPC APII Lab Cardio

What is the Endocardium & its function? Innermost lining of the heart; decrease friction.
What is the Myocardium & its function? cardiac muscle; contracts & pumps blood
What is the Epicardium & its function? inner visceral layer of serous pericardium; allows heart to move at contraction
What is the direction of blood flow through the heart? From SVC & IVC & CS < RA < RV < PA < Lungs < PV < LA < LV < Aorta < Systemic Circ.
What are the O2 & CO2 levels at various stages of blood flow? From SVC/IVC/CS until blood rec'd @ lungs O2 is low & CO2 is high; From lungs to syst. circ. O2 is high & CO2 is low.
What is the route of the Conduction System? SA Node < AV Node < AV Bundle of HIS < R&L Bundle Branches < Purkingje Fibers
What are the electrical events? Depolarization & Repolarization
What is ECG? A record of the electrical conduction through the cardiac muscle
Normal Sinus Rhythm Every normal P wave follwed by a normal ventricular response (QRST)
Primary function of Intercalated Disc? Allowing for rapid depolarization of cardiac muscle (fiber /tissue /cell).
What are Striations? Thick(myosin) & thin(actin) contractile filaments that produce movement
Sinus Bradycardia PQRST appears normal, T-P distance LENGTHENED
Sinus Tachycardia PQRST appears normal; T-P distance SHORTENED
Atrial Flutter "Saw-toothed" P Waves, PQRST appears normal
Atrial Fibrillation Erratic P Waves, PQRST appears normal, no atrial pumping
Ventricular Tachycardia BIG, Tall Dominant QRS, Ps & Ts can't be seen
Ventricular Fibrillation NO Obvious pattern to erratic QRS, Ps & Ts can't be seen, quiver/no ventricular pumping = death
Atrioventricular Block Appears to be missing some QRS, variable lenght gap between P & QRS
