I'm sorry you're experiencing heart irregularities and tachycardia (rapid heartbeat) during your R-CHOP treatment. This is an important concern that deserves immediate attention from your care team.
Why This Matters
Heart problems during lymphoma treatment are a recognized concern because R-CHOP includes doxorubicin (Adriamycin), which can affect heart function. The "A" in R-CHOP stands for this drug, and it's known to potentially cause:
- Irregular heartbeats (arrhythmias) like what you're experiencing
- Tachycardia (elevated heart rate)
- Changes in heart muscle strength over time
Since this is your second occurrence, this is definitely something your oncology team needs to know about right away if they don't already.
What You Should Do Immediately
Please contact your oncologist or go to urgent care/ER if you're experiencing:
- Chest pain or pressure
- Severe shortness of breath
- Fainting or dizziness
- Persistent rapid heartbeat
Questions to Ask Your Oncology Team
-
"Should I have cardiac monitoring (EKG or echocardiogram) before my next R-CHOP dose?" - Your team may want to check your heart function before continuing treatment.
-
"Is my heart function being monitored during treatment?" - Many centers do baseline and periodic heart assessments during R-CHOP.
-
"Could we adjust my treatment plan given these cardiac symptoms?" - There may be options like dose modifications or alternative approaches.
-
"Should I see a cardiologist?" - A heart specialist can evaluate whether your symptoms are treatment-related and recommend management.
-
"Are there medications that could help manage the tachycardia while I continue treatment?"
Important Context
While some patients do experience cardiac side effects during R-CHOP, not everyone does, and the severity varies widely. According to NCCN Guidelines for lymphoma treatment, cardiac monitoring is an important part of managing patients on this regimen. Your symptoms warrant a conversation with your team about whether continuing at the current dose is safe, or if adjustments are needed.
This is not something to wait on. Heart rhythm changes need prompt evaluation to ensure your safety and determine the best path forward for your lymphoma treatment.
