BIOC34H3 Chapter Notes -Stroke Volume, Cholinergic, Heart Valve
Document Summary
Bioc33/cc4 cardiovascular system (lectures 1-4) study guide (2011) Lecture 2: cardiac action potential and the electrocardiogram. Correlation of the ect components with the electrical conduction through the heart. 3: atrial flutter, atrial fibrillation, ventricular fibrillation, wandering atrial pacemaker, second degree heart block. Lecture 3: ecgs, electrical axis of the heart and the cardiac cycle. Pressure and volume changes during the cardiac cycle. Sample questions: what are the characteristics of ventricular fibrillation, describe the changes in atrial pressure, ventricular pressure, aortic pressure and ventricular volume that occur during the various stages of the cardiac cycle. Magnitude of the qrs complex in lead i = 2. Magnitude of the qrs complex in lead ii = 5. Magnitude of the qrs complex in lead iii = 3: approximately 33 , approximately 43 , approximately 67 , approximately 90 , approximately 115 . Lecture 4: cardiac cycle continued and regulation of cardiac output. Effects of adrenergic and cholinergic input on the pacemaker potential.
