Palpitations are more pronounced when lying down or at rest?
Six months ago, I suddenly became very aware of my heartbeat while sleeping (60-70 beats per minute, regular and stable, with normal blood pressure).
It felt like my whole body was shaking.
It was not like typical palpitations that are particularly strong or fast.
I consulted a cardiologist, and after undergoing an echocardiogram, an electrocardiogram, and a 24-hour Holter monitor, they found only mild prolapse of the mitral and tricuspid valves, concluding that there were no significant abnormalities.
Because the noticeable heartbeat made it difficult for me to fall asleep, leading to insomnia, I sought help from a psychiatrist.
After taking Sertraline without significant effect, my doctor and I decided to switch to Venlafaxine.
I have been taking it regularly for six months now, but I still feel my heartbeat particularly strongly when lying flat or sitting still (with my back against the chair).
My daily routine is normal, with no smoking, alcohol, or stimulating foods, and I have been doing regular aerobic exercise in the morning and evening for six months, but the issue of noticeable heartbeat has not improved.
I can only rely on sleeping pills to fall asleep, which is very distressing.
My main complaint is that the noticeable heartbeat has not improved, leading to insomnia.
I would like to ask the doctor what further directions I can explore for examination.

Hello: If you have already undergone cardiac-related examinations and confirmed that there are no abnormalities, it is recommended to continue monitoring and follow-up.

More Info
Experiencing a persistent sensation of your heartbeat, especially when lying down, can be quite distressing and may significantly affect your quality of life, including your sleep. Based on your description, it seems that you have undergone a thorough evaluation by a cardiologist, including echocardiograms and Holter monitoring, which have indicated mild mitral valve prolapse but no significant abnormalities. This is reassuring, as it suggests that there are no major structural heart issues contributing to your symptoms.
Mitral valve prolapse (MVP) is a common condition, particularly among women, and it can sometimes lead to symptoms such as palpitations, anxiety, and even panic attacks. The sensation of your heartbeat being more pronounced when lying down could be related to several factors, including changes in body position, increased awareness of bodily sensations in a quiet environment, or even anxiety and stress, which can amplify the perception of heartbeats.
Here are some potential avenues to explore further:
1. Anxiety and Stress Management: Since you have already consulted a psychiatrist and are on medication, it may be beneficial to also explore non-pharmacological approaches to manage anxiety. Cognitive-behavioral therapy (CBT) has been shown to be effective for anxiety and may help you develop coping strategies for your symptoms. Mindfulness and relaxation techniques, such as deep breathing exercises, yoga, or meditation, can also be beneficial in reducing anxiety and improving your overall sense of well-being.
2. Sleep Hygiene: Since your symptoms are affecting your sleep, it's essential to practice good sleep hygiene. This includes maintaining a regular sleep schedule, creating a comfortable sleep environment, and avoiding stimulants (like caffeine) close to bedtime. Engaging in a calming pre-sleep routine can also help signal to your body that it’s time to wind down.
3. Physical Activity: While you mentioned that you engage in regular aerobic exercise, consider incorporating relaxation-focused activities such as tai chi or gentle yoga, which can help reduce stress and improve your body’s response to anxiety.
4. Further Cardiac Evaluation: If your symptoms persist despite these interventions, it may be worth discussing with your cardiologist the possibility of further evaluations. This could include an exercise stress test or an event monitor to capture any intermittent symptoms that may not have been recorded during the initial assessments.
5. Dietary Considerations: Although you mentioned that you maintain a healthy diet, it may be worth reviewing your intake of certain substances that can affect heart rhythm and perception, such as caffeine, alcohol, and high-sugar foods. Staying well-hydrated and ensuring adequate electrolyte balance (potassium, magnesium) can also be beneficial.
6. Medication Review: Since you have been on medication for anxiety and sleep, it might be helpful to have a thorough review with your prescribing physician. Sometimes, medications can have side effects that may exacerbate feelings of palpitations or anxiety.
7. Support Groups: Connecting with others who experience similar symptoms can provide emotional support and practical advice. Consider seeking out support groups for individuals with anxiety or heart-related conditions.
In conclusion, while your cardiac evaluations have not indicated any serious underlying issues, the persistent sensation of your heartbeat can be multifactorial, often intertwined with anxiety and stress. A holistic approach that includes both medical and psychological strategies may provide the best relief. It’s essential to maintain open communication with your healthcare providers about your symptoms and any changes you experience as you explore these options.
