What could cause a very rapid vibrating sensation from the
I'm quite sure this is not a cardiac symptom. I can sense my heartbeat when lying on my side in bed, and it seems entirely normal. I have no associated breathlessness or dizziness such as might be caused by arrhythmia, and the sensation I'm asking about is much too rapid to be an arrhythmia, I believe.
Hello dear, welcome to Ask a doctor service.
I read your query and here is my advice.
Most probably this is a symptom of laryngeal inflammation possibly viral. The thing that it us more evident at night when you lay down it has to do with the secretions from trachea or bronches move up causing the vibration sensation and inflammation which is also causing hoarseness.
Taking antihistamines such desloratadine can help you with cough, hoarseness and vibration sensation.
This has nothing to do with heart disease or arythmia.
Another possibility is of it being anxiety symptoms.
Hope I have answered the question.
Let me know if I can assist you further.
