Patient's Query

Hi doctor,

In 2017, a mediastinal mass was found in my body and I was diagnosed with lymphoma. One year after the treatment, I started having a lot of fatigue and tachycardia like 160 bpm at rest, and my blood pressure was mostly low (70/40 mmHg).

Now, I am taking the tablet Ivabradine 7.5 mg and the tablet Bisoprolol 5 mg twice a day. I still do not feel good and after a couple of weeks, my heart rate has increased again (above 100 bpm). All the blood investigations for the heart are fine.

I got a CT done after taking the treatment for the lymphoma and growth of 10x11 mm was seen in it. However, now I have got another CT done and it says that the growth is 19x11 mm and there is some 'radiotherapy collateral damage'.

I want your opinion on this.

Welcome to icliniq.com.

There is a possibility that the chemotherapeutic drug might have had some side effect on your heart. For that, I will need to know all the medications you had taken and all the CT (computed tomography) and blood reports of the heart, then only I can comment upon your illness.

Secondly, there might also be a possibility that this is all a part of anxiety and stress.

However, in any of the scenarios, it is completely manageable. Do not worry.

You will be fine. Just share all the reports.

Hope this helps you.

Kindly revert back in case of further queries.

Thank you.
