ATRIAL CONTRACTION- COMPRESSES AND MOVE BLOOD TO VENTRICLES
VENTRICLE CONTRACTION- BEGINS AT APEX AND MOVES UPWARD COMPRESSES SUPERIORLY AND MOVES BLOOD OUT OF THE HEART |

SINOATRIAL NODE(SA NODE)- PACEMAKER OF HEART IN POSTERIOR WALL OA ATRIUM
ATIOVENTRICULAR NODE(AV NODE)- ALSO CALLED AV BUNDLE, IN FLOOR OF RT ATRIUM NEXT TO OPENING OF CORONARY SINUS
ATIOVENTRICULAR BUNDLR(BUNDLE OF HIS)- EXTENDS FROM AV NODES THRU AV SEPTUM AND THE SPLITS INTO RT/LF AV BUNDLES
