I felt my heartbeat in shoulder blade. Why?

Hi,

Welcome to icliniq.com.

The pounding or racing heart rate you are experiencing is known as palpitations, that is, awareness of one's own heartbeat. They usually are not serious and go away on their own. They may occur during physical or emotional exertion, anxiety, stimulants like caffeine, nicotine, alcohol. Unlike that if you have chest pain, shortness of breath, or dizziness or syncope, you need medical attention and evaluation. Some of the causes are listed here under anxiety, physical exertion, heavy meals, alcohol, coffee, smoking, medication like for cough or asthma, fever, dehydration, hypoglycemia, hyperthyroidism, cardiac arrhythmias, cardiac failure, etc. So, now detail your history whether it is spontaneous or during exertion, or following any activity, fast regular or irregular, how many times a day, any associated with chest pain breathlessness or dizziness.
