What is a hyperdynamic chronotropic response in a Holter test?

Question

Hello doctor,

I have a few concerns regarding my Holter reports. Can you please guide me on:

What is a hyperdynamic chronotropic response?
Is this treatable?

These are the findings of my Holter, and I have been experiencing a high heart rate when I do physical activities, even walking. I just want to know if this is manageable or treatable?

None, it started when I drank coffee and experienced palpitations, then it did not go away after many days, and now, a year later, I still have it. Currently, I am taking 10 mg of Propranolol.

Kindly suggest.

Thank you.

Hello,

Welcome to icliniq.com.

I understand your concern.

Thank you for sharing your reports (the attachments were removed to protect the patient's identity), with us. I understand that symptoms related to heart rate can feel worrying, and it is completely natural to feel concerned when you see unfamiliar terms in a report.

Your Holter report shows that you have a hyperdynamic chronotropic response. It does not mean that you have any serious disease; it simply means that you had a fast heart rate at some point during the monitoring. According to the report, this was sinus in origin (normal).

The report does not show any record of any persistent ventricular rhythm, which would be considered dangerous.

Furthermore, your ECG (electrocardiogram) and echocardiogram were normal, which is very reassuring. Overall, the findings suggest that your heart structure and rhythm are within normal limits.

An irregular fast heart rate can often be managed through physical activity, exercise, and training. If it remains uncontrolled, medications such as beta-blockers can be used. Also, secondary causes of a fast heart rate, such as fever, thyroid issues, and anxiety, need to be taken care of.

Since you are already taking Propranolol 10 mg, the dose can be increased if clinically necessary, or you could be switched to a more suitable medication.

I hope this helps clarify your reports and eases your concerns and fears.

Please feel free to reach out if you have any further questions. I would be happy to help.

Thank you.
