No atrial contraction - Study guides, Class notes & Summaries

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...
