Question Answer
the cardiac cycle is an ____, then ventricular systole ___ and diastole ___Atrial, contraction, and relaxation
Electrocardiography is the measurement of the electrical activity of the hear
P wave representrepresents the depolarization of the atrial walls, which precedes atrial systole
QRS complexresults from the concurrent ventricular depolarization (preceding ventricular systole) and atrial repolarization (signaling the onset of atrial diastole)
T wave represent ventricular repolarization, which precedes ventricular diastole
function of the Sinoatrial (SA) nodenatural pacemaker of the hear
function of the Atrioventricular (AV) nodetakes the signal from the Sinoatrial (SA) Node, slows the signal down and regulates it, and then sends the electrical impulses from the atria to the ventricles (bundle of His).
function of the AV bundle (of His)it transmits impulses from the atrioventricular node to the ventricles of the heart
function of the Purkinje fibersPurkinje fibers allow the heart's conduction system to create synchronized contractions of its ventricles, and are, therefore, essential for maintaining a consistent heart rhythm.
identify arteries used to determine pulse.Carotid, brachial, radial, femoral, popliteal, posterior tibial, doralis pedis, temporal and apical
Know what the heart sounds (“lub-dup) indicate."lub" results from closure of the tricuspid and mitral valves. dub” or S2, is caused by the closure of aortic and pulmonic valves
blood pressure is measured by asphygmomanometer
