Should You Seek Hospital Evaluation for Persistent Heart Rate of 90-110? - Cardiology

When considering whether to seek hospital evaluation for a persistent heart rate of 90-110 beats per minute (BPM), especially in the context of your history of premature ventricular contractions (PVCs) and recent symptoms, it is essential to understand several factors.

Firstly, a resting heart rate between 90-110 BPM is generally considered elevated, particularly if it is sustained over time. While a heart rate in this range can be normal during physical activity or emotional stress, a persistent elevation at rest may indicate an underlying issue that warrants further investigation. In your case, the fact that you have a history of PVCs adds another layer of complexity, as these can sometimes lead to symptoms such as palpitations, dizziness, or even syncope (fainting) during exertion.

The symptoms you describe—feeling lightheaded when lifting heavy objects or bending over—are concerning and could be indicative of inadequate blood flow or cardiac output during these activities. This is particularly relevant given your history of PVCs, which can sometimes disrupt the normal rhythm of the heart and lead to decreased efficiency in pumping blood.
Moreover, the results of your exercise electrocardiogram (ECG) are crucial. If the test indicated any abnormalities, such as changes in the ST segment or other signs of ischemia, this would necessitate immediate follow-up. Even if the exercise ECG appeared normal, your persistent elevated heart rate and symptoms suggest that further evaluation may be warranted.

In general, if you are experiencing new or worsening symptoms, such as lightheadedness, especially in conjunction with a sustained elevated heart rate, it is advisable to consult with a healthcare provider. They may recommend additional testing, such as a Holter monitor (24-hour ECG), echocardiogram, or even a stress test, to assess your heart's function more thoroughly.
Additionally, it is essential to consider other potential causes of an elevated heart rate, including anxiety, dehydration, anemia, hyperthyroidism, or other metabolic conditions. A comprehensive evaluation can help rule out these possibilities and ensure that any necessary treatment is initiated promptly.

In summary, given your history of PVCs, the recent symptoms of lightheadedness, and the persistent heart rate of 90-110 BPM, it would be prudent to seek further evaluation from a healthcare provider. They can help determine the underlying cause of your symptoms and develop an appropriate management plan. Your health and safety are paramount, and addressing these concerns early can help prevent potential complications in the future.
