Med Surg II Exam 1 Questions and Answers Latest Updated Version. FOCUS POINTS EXAM 1 CARDIAC (MED SURG II EXAM 1) Dysrhythmias Abnormal heart rate or rhythm Caused by a disturbance in electrical conduction of the heart, not by abnormal heart structure May be benign or have lethal consequences Cardiac output = stroke volume x HR Patho ● 5 unique properties of cardiac cells ○ Automaticity → spontaneously initiate an electrical impulse ■ Changes in automaticity cause tachydysrhyth...

cardiac electrophysiology correct answer: study of the electrical properties of the cardiac muscle -electricity flows through the heart in a regular, measured pattern and results in contraction of the cardiac muscle -electrical activity precedes mechanical activity (contraction of the heart) -EKG looks at the electrical activity properties of cardiac cells correct answer: specialized cardiac cells have unique characteristics that allow them to regulate heart rate and rhythm characteri...
