I had this happen last night, and again today..  A pulsing starts in my chest, and intense throbbing headache comes on, then I start to sweat profusely.  I also get a little nausea, and begin to burp.  After lying down, the symptoms stop, accept for the headache, that remains as a dull ache.  Never had this before, but twice in two days now...
Palpitations with chest pain and headache usually point towards hypertension.please get your BP checked and also go for ECG chest x-ray also
