Document Summary
Cannot see depolarization of atria because it its buried in the qrs complex. Is don"t have this means issue with sa node. Q wave depolarization of the ventricular of septum 1 mv = 1mm. Starts with sa node/pacemaker (depolarization message to atria = atrial contraction, and stimulates) which starts in the right atria connects to the. Av node at the bottom corner of the atria, right near the inter ventricular septum. If av node is broken, will not set off right away, so the pr interval is really long. Nodes are still cardiac muscle if have heart attack that tissue can die and it will no longer function. Cicr, to increase stroke volume: moodle assingment, estimate, rough guess, of sv > for pulse pressure sbp - dbp . thinking narrow pulse pressure = bad, estimated cardiac output > !2: diaphragm, inverted u shaped muscle, fused to sack that surrounds the lung called the pleura.
