Which symptoms are associated with chemotherapy-related arrhythmias?

• A. Shortness of breath at rest
• B. Palpitations only during exercise
• C. Dizziness on standing
• D. Palpitations, dizziness, fainting episodes

Answer: (D)

Chemotherapy-related arrhythmias often present with a combination of symptoms that reflect an irregular or interrupted heart rhythm. Palpitations are a common clue, as the patient feels like the heart is racing, skipping, or fluttering. Dizziness occurs when the irregular rhythm reduces blood flow to the brain, and fainting episodes (syncope) can happen if the rhythm becomes markedly abnormal or pauses for too long. Together, these signs point to rhythm disturbances rather than issues like fluid overload or blood pressure changes alone. The other options are less specific to arrhythmias. Shortness of breath at rest can arise from heart failure or lung problems rather than an arrhythmia itself. Palpitations occurring only during exercise miss potential activity-independent rhythm problems. Dizziness on standing suggests orthostatic intolerance rather than an arrhythmic cause. Therefore, the combination of palpitations, dizziness, and fainting best fits chemotherapy-related arrhythmias.
