Post-COVID Heart Rate Increase: When to See a Cardiologist? - Cardiology

More Info

Post-COVID heart rate increase is a concern that many individuals are experiencing as a result of their COVID-19 infection. It is not uncommon for patients to notice changes in their heart rate following recovery from COVID-19, and this can manifest as tachycardia (an elevated heart rate) or palpitations. The symptoms you describe, including a heart rate fluctuating between 51 and 144 beats per minute, can indeed be related to your recent COVID-19 infection.

COVID-19 can affect the cardiovascular system in various ways. The virus can lead to inflammation, which may impact the heart muscle and the autonomic nervous system, potentially causing symptoms such as increased heart rate, palpitations, and even chest discomfort. This phenomenon is sometimes referred to as "post-acute sequelae of SARS-CoV-2 infection" (PASC), or more commonly, "long COVID."
In your case, the fact that you have recently tested positive for COVID-19 and are experiencing an increased heart rate suggests that there may be a connection. It is important to monitor your symptoms closely. While some degree of heart rate increase can be a normal response to illness, especially when accompanied by fever and other symptoms, persistent tachycardia or significant fluctuations in heart rate warrant further evaluation.

Here are some considerations regarding when to see a cardiologist:
1. Persistent Symptoms: If your elevated heart rate continues for an extended period, or if you experience additional symptoms such as chest pain, shortness of breath, dizziness, or fainting, it is advisable to seek medical attention.

2. Severity of Symptoms: If you find that your heart rate is consistently above 100 beats per minute while at rest or if you feel that your heart is racing uncontrollably, this is a sign that you should consult a healthcare professional.

3. Underlying Conditions: If you have pre-existing heart conditions or risk factors (such as hypertension, diabetes, or a family history of heart disease), it is prudent to have a cardiologist evaluate your heart health.

4. Follow-Up Care: Since you have already seen a doctor and received treatment for your COVID-19 symptoms, it may be beneficial to follow up with a cardiologist for a more specialized assessment, especially if your heart rate does not return to baseline or if you have concerns about your heart health.

5. Monitoring: Continue to monitor your heart rate using your Apple Watch or any other device. Keep a record of your heart rate patterns, especially during different activities (resting, standing, exercising), and share this information with your healthcare provider.

In conclusion, while an increased heart rate can be a common response to COVID-19, it is essential to remain vigilant and proactive about your health. If your symptoms persist or worsen, or if you have any concerns about your heart rate or overall cardiovascular health, do not hesitate to reach out to a cardiologist for a thorough evaluation. They may recommend further testing, such as an electrocardiogram (ECG), echocardiogram, or Holter monitor, to assess your heart's function and rule out any underlying issues. Taking these steps can help ensure that you receive appropriate care and support as you recover from COVID-19.
