Dear Patient,
Thank you for reaching out with your concerns regarding your medication and heart rhythm issues. It’s understandable to feel anxious when experiencing symptoms like irregular heartbeats, especially when they coincide with changes in your medication regimen. Let’s break down your situation and address your concerns.

First, it’s important to understand that beta-blockers, such as the one you mentioned (康肯, or Carvedilol), are commonly prescribed for various cardiovascular conditions, including hypertension and heart rhythm disorders. They work by blocking the effects of adrenaline on the heart, which can help to lower heart rate and blood pressure. However, like any medication, they can have side effects, and in some cases, they may lead to or exacerbate existing heart rhythm issues.

You mentioned that after reducing your dosage to half, you still experience feelings of irregular heartbeats. This sensation, often described as palpitations, can be concerning. While beta-blockers are generally used to manage arrhythmias, they can sometimes lead to a phenomenon known as "rebound tachycardia" or other rhythm disturbances, particularly if the body is adjusting to the medication change. It’s also worth noting that anxiety and stress can contribute to the perception of palpitations, which can complicate the situation.

Given that you have noticed these irregularities since changing your dosage, it is advisable to consult your healthcare provider. They can perform a thorough evaluation, which may include an electrocardiogram (ECG) or a Holter monitor to assess your heart rhythm over a period of time. This will help determine if the irregularities you are experiencing are significant and if they are related to the medication.

In terms of management, it’s crucial not to make any changes to your medication without consulting your doctor. If your doctor suspects that the beta-blocker is contributing to your symptoms, they may consider adjusting your dosage further or switching you to a different class of medication that may be better tolerated.
Additionally, if you experience any alarming symptoms such as chest pain, severe shortness of breath, or fainting, seek immediate medical attention. These could be signs of a more serious condition that requires urgent evaluation.

In summary, while beta-blockers can sometimes lead to irregular heart rhythms, it’s essential to discuss your symptoms with your healthcare provider. They can provide personalized advice based on your medical history and current condition. Regular follow-up is key in managing heart rhythm issues and ensuring that your treatment plan is effective and safe.

Take care, and I hope you find relief soon.

Best regards.
