When assessing a patient with mitral valve stenosis, which of the following cardiac rhythms would the nurse anticipate the patient would demonstrate?
1. third-degree heart block
2. atrial fibrillation
3. ventricular tachycardia
4. junctional pacing
2
Rationale: With mitral valve stenosis the left atrial pressure raises and leads to changes in the left atrial electrical refractory period, which may precipitate atrial fibrillation. The other three arrhythmias are not associated with mitral valve stenosis.
