Hello! Thank you for your detailed inquiry regarding the sensation of heartbeat during sleep and its associated symptoms. Let's break down your concerns and provide some insights based on medical knowledge.

1. Understanding Heartbeat Sensation: The sensation of feeling your heartbeat, especially when lying down, can be quite common and may not necessarily indicate a pathological condition. This sensation is often referred to as "palpitations." Palpitations can occur regardless of whether the heart rate is fast or normal. They can be triggered by various factors, including anxiety, stress, caffeine intake, or even certain medications. In your case, since you mentioned that your heart rate is usually around 100 beats per minute, this could be a contributing factor, especially if you are experiencing anxiety or stress.

2. Is This Considered Palpitations?: While you are not experiencing a rapid heartbeat (tachycardia) or irregular heart rhythms (arrhythmias), the sensation of your heart beating strongly or noticeably can still be classified as palpitations. It's important to note that palpitations can be benign, especially if they are not associated with other concerning symptoms such as chest pain, shortness of breath, or fainting.

3. Need for Further Investigation: You mentioned that you have undergone a 24-hour Holter monitor test, which did not reveal any issues. This is a good first step in evaluating your heart's rhythm. If your symptoms persist or worsen, it may be worthwhile to consult with a cardiologist for further evaluation. Additional tests, such as an echocardiogram or stress test, may be recommended based on your clinical history and symptoms. However, if your palpitations are infrequent and not associated with any alarming symptoms, further testing may not be necessary.

4. Effectiveness of Sedative Medications: The medications you mentioned, such as the mild sedative (Estazolam) and the anxiolytic (Rifampicin), can indeed help reduce the sensation of your heartbeat. These medications work by calming the central nervous system, which can alleviate anxiety and promote relaxation. This, in turn, may reduce the awareness of your heartbeat and help you sleep better. However, it's essential to use these medications under the guidance of a healthcare professional, as they can have side effects and may lead to dependency if used long-term.

5. Lifestyle Modifications: In addition to medication, consider implementing lifestyle changes that may help reduce anxiety and improve sleep quality. These can include:
- Reducing Caffeine Intake: Limit your consumption of caffeinated beverages, especially in the afternoon and evening.

- Establishing a Sleep Routine: Try to go to bed and wake up at the same time every day to regulate your sleep cycle.

- Relaxation Techniques: Engage in relaxation exercises such as deep breathing, meditation, or yoga before bedtime to help calm your mind.

- Physical Activity: Regular exercise can help reduce anxiety and improve sleep quality, but try to avoid vigorous workouts close to bedtime.

In summary, while the sensation of your heartbeat during sleep can be concerning, it is often benign, especially if not accompanied by other symptoms. Monitoring your lifestyle, managing stress, and consulting with a healthcare provider for personalized advice can help you address these concerns effectively. If symptoms persist or worsen, further evaluation may be warranted. Thank you for your question, and I hope this information helps you find relief and peace of mind!
