Is It Just Sinus Tachycardia? Your Heart Symptoms

Is it only sinus tachycardia?

I previously went to Taichung Veterans General Hospital for a 24-hour electrocardiogram, and the doctor diagnosed me with sinus tachycardia.
They prescribed me a 7-day supply of "Xin Kang Le," but after taking it, I feel it has had no effect on my palpitations.
I always experience episodes during morning meetings, and at the graduation ceremony the day before yesterday, I even felt numb all over.
Our school nurse mentioned that this could be due to hypoxia.
Additionally, I have been experiencing episodes in my sleep, usually around 4 AM.
Should I be concerned that this is just simple sinus tachycardia? Do I need to return to Taichung Veterans General Hospital for further examination, or would it be better to switch to another hospital?

Based on the above symptoms, the likelihood of hyperventilation syndrome is quite high.
If thyroid function is normal, symptoms should improve with lifestyle changes that reduce stress and tension, which should help!

More Info

Sinus tachycardia, or an elevated heart rate originating from the sinus node, can often be a benign condition, especially in younger individuals without significant underlying health issues. However, your symptoms, including episodes of palpitations, feelings of lightheadedness, and episodes occurring during sleep, warrant further evaluation.
The fact that you experienced full-body numbness during a stressful event, such as a graduation ceremony, raises some concerns. While it is possible that this could be related to anxiety or hyperventilation, it is essential to rule out any underlying cardiac issues. The sensation of numbness can sometimes be associated with decreased blood flow or oxygenation, which could be exacerbated by rapid heart rates or panic attacks.
Your report of symptoms occurring primarily in the early morning hours, particularly around 4 AM, could suggest a few possibilities. One consideration is that you may be experiencing nocturnal panic attacks or anxiety episodes, which can lead to increased heart rates and feelings of palpitations upon waking. Sleep disturbances can also contribute to heightened anxiety and exacerbate symptoms of tachycardia.
In terms of your treatment with "心康樂" (likely a beta-blocker or similar medication), it is not uncommon for individuals to experience varying degrees of effectiveness with such medications. If you find that your symptoms persist despite medication, it may be beneficial to discuss this with your healthcare provider. They might consider adjusting your treatment plan or exploring other therapeutic options.
Given your ongoing symptoms, it would be prudent to follow up with a cardiologist or return to your healthcare provider for further evaluation. A 24-hour Holter monitor may provide additional insights into your heart's rhythm during daily activities and sleep. Additionally, an echocardiogram or stress test could help assess your heart's function and response to exertion.
It is also essential to consider lifestyle factors that may be contributing to your symptoms. Stress management techniques, regular physical activity, and a balanced diet can significantly impact heart health and overall well-being. Reducing caffeine intake and ensuring adequate sleep can also help mitigate symptoms of anxiety and tachycardia.

In summary, while sinus tachycardia can be a benign condition, your symptoms suggest that further evaluation is warranted. It may be beneficial to return to your current healthcare provider or seek a second opinion from another cardiology specialist. They can help determine if there are any underlying conditions that need to be addressed and guide you toward appropriate management strategies to alleviate your symptoms.
