Cardiac Dysrhythmias (Adapt- Exam 2)Cardiac dysrhythmias affect perfusion by reducing the efficiency of the heart's pumping
cycle. Which factors contribute to the reduction in efficiency? Select all that apply. -
answer-Irregular contractions that interfere with normal filling
-Preventing adequate filling during diastole with rapid heart rate
-Heart rate fluctuation between 60-100
-Conduction from the sinoatrial to the atrioventricular node
-Very slow heart rate reducing output to tissue
Atrial Fibrillation (A-Fib) - answerThe conduction system is disrupted, and electrical
signals move erratically around the atria.
Atrial Flutter - answerIt is caused when electrical impulses begin in a different spot
inside the atria instead of the SA node and the impulse begins to travel through the atria
in a circuit (a closed loop).
ventricular fibrillation - answerThe conduction system is disrupted, and electrical signals
move erratically around the ventricles.
ventricular tachycardia - answerThe conduction system is disrupted and causes the
ventricles to beat quickly and not in harmony with the atria (upper chambers).
What is the natural Pacemaker of the heart? - answerSA node
What are Cardiac Dysrhythmias? - answerthey are irregular or abnormal electrical
signals that may cause the heart to contract too quickly, too slowly, or in an abnormal
direction.
Dysrhythmias can be caused by - answerfluid and electrolyte imbalances (especially
potassium), fever, medication toxicity, stress, infection, or hypoxia (not enough oxygen
in the blood).
- Calcium imbalances
- Injury to heart itself
-
Some dysrhythmias require what to stop them? - answer- electricity
- others may require a pacemaker to ensure regularity
- medications
