Third Degree Heart Block correct answer: Occurs when atrial impulses are completely blocked at the AV node and fail to reach the ventricle; atria and ventricles are controlled by different and independent pacemakers Third Degree Heart Block Causes correct answer: inferior or anteroseptal MI ...

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) -EK...

Dysrhythmia correct answer: Any disorder of the heart beat or heart rhythm. Cardiac output is impaired. Cellular oxygenation is then also impaired Electrical problem will definitely effect the mechanical but a mechanical problem may not effect the electrical. Explaining dysrhythmias correct...
