Anxiety or heart problems?


Hello, Doctor.
I apologize for bothering you, but I would like to ask about some symptoms I've been experiencing lately.
Sometimes, I feel like my heartbeat is irregular, and I can feel it more easily when I'm trying to sleep.
When I notice my heartbeat, it becomes bothersome.
Could this be due to anxiety? I previously had an echocardiogram that showed normal results, with only mild mitral and tricuspid regurgitation.
Is this a common issue?
In the past, I was prescribed Inderal for occasional premature ventricular contractions (VPC), which helped, but when I stopped taking it, I noticed my heart rate increased.
My doctor has recently prescribed Inderal for me to take twice a day, but I'm hesitant to take it long-term and prefer to use it only when necessary.
Lately, my doctor has prescribed it again because I tend to feel anxious.
Sometimes my heart rate ranges from 90 to 120 beats per minute, and during panic attacks, it can spike to 160-170.

Doctor, I've been feeling that my heart is acting strangely, and sometimes my body shakes.
Are these symptoms related to anxiety? Should I just ignore them? Is there any danger involved? Additionally, if I take one dose of Inderal in the morning and one at night, is that sufficient for its effect, or will it cause fluctuations in my heart rate? Is the mechanism of action of Concor (Bisoprolol) more extensive than that of Inderal? Does that mean Inderal has fewer side effects compared to Concor?
Am I often feeling discomfort in my heart when there is actually nothing wrong with it? Can anxiety truly cause someone to feel like their heart is acting strangely? I apologize for all these questions, and thank you, Doctor.
Take care.

Hello, the trembling of your body is a symptom of anxiety.
Anxiety can make you feel like your heart is acting strangely, but there is no issue with your heart.
Mild mitral and tricuspid regurgitation is quite common and almost everyone has it, so your echocardiogram results are normal.
Concerning Inderal, it is very similar; the main difference is between long-acting and short-acting formulations.
If you are hesitant to take it long-term, it's worth noting that the side effects of Inderal are generally minimal.
Not taking medication out of fear can lead to increased anxiety, which would be counterproductive.
It’s more important to focus on living well in the present.
Don't worry about side effects; just take your medication as prescribed.
Your well-being is important, and Changhua Hospital cares about you.

It's understandable to feel anxious when experiencing unusual heart sensations, especially if you have a history of heart issues and anxiety. Based on your description, it seems likely that your symptoms may be related to anxiety rather than a serious heart condition, especially since you have previously undergone tests like echocardiograms that showed only mild mitral and tricuspid regurgitation, which are generally not considered serious.

Anxiety can manifest in various physical symptoms, including palpitations, a racing heart, and even feelings of trembling or shaking. These symptoms can be exacerbated by stress or anxiety, leading to a cycle where the more you focus on your heart rate, the more anxious you become, which in turn can increase your heart rate further. This is often referred to as a "vicious cycle" of anxiety and physical symptoms.

Regarding your heart rate, a resting heart rate between 90-120 beats per minute can be considered elevated, especially if you are at rest. However, during periods of anxiety or panic attacks, it is not uncommon for heart rates to spike even higher, sometimes reaching 160-170 beats per minute. This is typically a physiological response to stress or anxiety, known as the "fight or flight" response, where your body prepares to react to perceived threats.

Inderal (propranolol) is a beta-blocker that can help manage physical symptoms of anxiety, such as palpitations and tremors. It works by blocking the effects of adrenaline on your heart, which can help to lower your heart rate and reduce feelings of anxiety. Taking Inderal as prescribed, especially during times of increased anxiety, can be beneficial. However, it is important to follow your doctor's guidance regarding long-term use, as beta-blockers are generally intended for short-term management of symptoms rather than long-term treatment of anxiety.

As for your question about whether to ignore your symptoms, it's essential to listen to your body. While anxiety can certainly cause sensations that feel concerning, if you ever experience severe symptoms such as chest pain, shortness of breath, or fainting, you should seek medical attention immediately. It's always better to err on the side of caution when it comes to heart health.

In terms of medication, if you feel that the Inderal is not providing consistent relief, it may be worth discussing with your doctor whether adjustments to your dosage or a different medication might be more effective. There are various options available for managing anxiety, including other medications and therapeutic approaches such as cognitive-behavioral therapy (CBT), which can help address the underlying anxiety rather than just the physical symptoms.

Lastly, it's important to remember that anxiety can indeed cause real physical sensations that can mimic heart problems. This is a common experience among those with anxiety disorders. Engaging in relaxation techniques, mindfulness, and regular physical activity can also help manage anxiety symptoms and improve your overall well-being.

In summary, while your symptoms may be anxiety-related, it's crucial to maintain open communication with your healthcare provider about your experiences and treatment options. They can help you navigate your symptoms and find the most effective strategies for managing both your anxiety and any physical sensations you may be experiencing.
