Location of Base of heart Location of the Heart location of apex of heart Location of point of maximal impulse Systole Isovolumetric ventricular contraction Ventricular Ejection Diastole Isovolumetric ventricular relaxation Ventricular Filling SA Node AV Node It's the widest part Runs across 2nd intercostal space Approx. 2/3 to the left of the mid-sternal line Tip of term-7the heart at the 5th intercostal space, medial to left mid-clavicular line Apex of Heart Isovolumetric ventricular contraction Ventricular ejection Atria relaxed All Valves are closed Atria relaxed Ventricles contract AV valves: Closed Aortic/Pulmonary Valves: Open Isovolumetric ventricular relaxation Ventricular filling Atria relaxed Ventricles relaxed All Valves: Closed Atria relaxed then contracts Ventricles relaxed AV valves: Open Aortic/pulmonary vales: Closed pacemaker of the heart Rate: 60-100 bpm Stimulates atria contraction Heavily innervated by both SNS and PNS Back-up Pacemaker to SA node Junctional rhythms rate: 40-60 bpm Slows impulses coming from SA to the ventricle Screens rapid atrial impulses to protect
