Answer: reentry of impulse
◉ Normal calcium levels. Answer: 9-10.5 mg/dL
◉ Normal magnesium levels. Answer: 1.7-2.2 mg/dL
◉ How would kidney dz increase the risk for dysrhythmias?.
Answer: inability to excrete K+
◉ Two major concepts related to dysrhythmias. Answer: 1.
perfusion: decreased CO
2. oxygenation: decreased O2
, ◉ Normal conduction ensures that the circulation of blood occurs in
an _____ manner. With abnormal conduction, blood circulates in an
_______ manner, causing decreased ______ to the body and increased
risk for ______.. Answer: even, uneven, perfusion, emboli
◉ True or false: every cardiac cell has the potential to produce an
impulse.. Answer: TRUE
◉ Explain the movement of a NORMAL impulse through the heart.
