Managing Anxiety and Panic Attacks with Heart Rhythm Disorders: A Guide - Psychiatry

Medication consultation, drug side effects, panic, autonomic nervous system dysregulation?


I would like to ask the doctor, I have a history of arrhythmia and have undergone echocardiography, a 24-hour Holter monitor, and an exercise stress test, which detected premature ventricular and atrial contractions.
I was prescribed antiarrhythmic medication that I took for over six months, after which my doctor advised that I could keep the medication on hand to take as needed.
Later, after being diagnosed with an autoimmune disease, I began to experience various discomforts throughout my body (I am taking Prednisone and Plaquenil).
One day, I started feeling a sensation of a foreign body in my right throat, and sometimes food feels like it gets stuck when I swallow.
I constantly feel like my right throat is being constricted, and my nose feels stuffy (though I don’t have nasal congestion), leading to a sensation of difficulty breathing.
I underwent an upper endoscopy, laryngoscopy, and sinus X-rays, all of which showed no abnormalities.
My pulmonary function tests were also within normal limits, although they indicated possible tracheal narrowing, which my doctor said was not concerning.
However, I have been experiencing sudden episodes of rapid heartbeat without warning, accompanied by numbness throughout my body, trembling limbs, and a feeling of impending suffocation.
I have visited the emergency room multiple times.
It has now become that whenever I go to the basement or a more enclosed space, or in crowded areas, or when I exert myself while walking, I experience increased difficulty breathing.
This has led to a growing aversion to such situations, as I feel like I might suffocate at any moment.
I start to panic in places where I feel the air is thin or where there are no hospitals nearby.
I later consulted a psychiatrist, who prescribed me Clonazepam, Buspirone, and Hydroxyzine to take at bedtime (adjusted to a dose that wouldn’t make me feel excessively sleepy in the morning).
I was also given Hydroxyzine to keep on hand (which I haven’t taken yet).
After taking these medications for a while, the sensation of pressure is still present, but I don’t focus on it as much as before.
I would like to know if this sensation of pressure will improve? It has been with me for two years, but the cause remains elusive.
Additionally, since I am about to travel abroad, I am worried about having an episode on the plane, especially since I haven’t flown in several years.
My flight is early in the morning, and if I take those three medications around 9 or 10 PM before bed, I should be fine when I wake up at 3 AM for a 6 AM flight, right? If I do have an episode, is it urgent to take Hydroxyzine at that moment? Will it cause drowsiness? After all, it’s only a little over an hour flight.
Is there a better way to manage this? Recently, due to my arrhythmia, I have started taking an antiarrhythmic medication both morning and night.
Thank you for your response.

Hello.
Your condition is likely related to anxiety (autonomic nervous system dysregulation).
It is advisable to continue visiting a psychosomatic medicine specialist for improvement.
You may use Yuli Shu as a backup medication.
If you are concerned about potential side effects such as drowsiness, you can try it out during regular times to determine if it is suitable for you.
Thank you.

Managing anxiety and panic attacks, especially when coupled with heart rhythm disorders, can be a complex and challenging endeavor. Your situation, characterized by a history of heart rhythm irregularities, anxiety, and recent physical discomforts, requires a multifaceted approach that addresses both the psychological and physiological aspects of your health.


Understanding Your Condition
From your description, it appears that you have undergone extensive cardiac evaluations, including echocardiograms and Holter monitoring, which have shown that your heart structure and function are generally normal, with some instances of premature ventricular contractions (PVCs) and premature atrial contractions (PACs). These findings are not uncommon and, in many cases, are benign, especially in the absence of significant symptoms or underlying heart disease.

However, the presence of anxiety and panic attacks can exacerbate the perception of these heart rhythm irregularities. Anxiety can lead to heightened awareness of bodily sensations, which may cause you to misinterpret normal physiological responses (like increased heart rate or palpitations) as dangerous. This cycle can create a feedback loop where anxiety leads to physical symptoms, which in turn increases anxiety.


Managing Anxiety and Panic Attacks
1. Medication Management: You mentioned taking medications such as Klonopin (Clonazepam) and other anxiolytics. These can be effective in managing acute anxiety and panic attacks. However, it's crucial to work closely with your psychiatrist or primary care physician to ensure that your medication regimen is appropriate for your specific needs. If you experience excessive sedation or other side effects, discussing alternative medications or dosages may be beneficial.

2. Cognitive Behavioral Therapy (CBT): Engaging in CBT can help you identify and challenge irrational thoughts related to your health and anxiety. This therapeutic approach is particularly effective for anxiety disorders and can provide you with coping strategies to manage panic attacks when they occur.

3. Relaxation Techniques: Incorporating relaxation techniques such as deep breathing exercises, progressive muscle relaxation, or mindfulness meditation can help reduce anxiety levels. These practices can also be beneficial in moments of acute anxiety or panic, helping to calm your physiological response.

4. Gradual Exposure: Since you mentioned a fear of flying and being in enclosed spaces, gradual exposure to these situations can help desensitize your anxiety response. Start with smaller, controlled environments and gradually work your way up to more challenging situations, such as being in a crowded area or taking a short flight.

5. Lifestyle Modifications: Regular physical activity, a balanced diet, and adequate sleep can significantly impact your overall mental health. Engaging in regular exercise can help reduce anxiety and improve your mood. Additionally, avoiding stimulants such as caffeine and nicotine can help minimize anxiety symptoms.


Preparing for Your Flight
Regarding your upcoming flight, it’s understandable to feel anxious, especially given your history. Here are some tips to help you prepare:
- Medication Timing: Taking your prescribed medications as directed, including your anxiolytics, can help manage anxiety during your flight. If you take them before bed, ensure you allow enough time for the medication to take effect before your early morning flight.

- Emergency Plan: If you feel a panic attack coming on during the flight, having your emergency medication (like the one you mentioned) readily available can provide peace of mind. Discuss with your doctor whether taking it preemptively or at the onset of symptoms is advisable.

- Stay Hydrated and Nourished: Dehydration and hunger can exacerbate feelings of anxiety. Make sure to drink water and have a light snack before and during your flight.

- Breathing Exercises: Practice deep breathing techniques before and during the flight. This can help calm your nervous system and reduce the likelihood of a panic attack.


Conclusion
While your concerns are valid, it’s essential to remember that many individuals with similar conditions successfully manage their symptoms and lead fulfilling lives. By combining medication, therapy, lifestyle changes, and preparation strategies, you can effectively manage your anxiety and heart rhythm issues. Always consult with your healthcare provider before making any changes to your treatment plan, especially as you prepare for your flight. Safe travels!
