Over the last 6 months I have started to have occasional palpitations which tend to last an hour or so. Often, if the palpitations are less than 160bpm I perform the valsalva manouver, my heart rate goes slightly faster and then drops back to normal. I have had these palpatations spike up to 196bpm on occasions. The palpitations usually take around 2-3 seconds to reach their maximum speed, remain for a few minutes and then return to normal within 2-3 seconds.
I have noticed that these palpitations usually occur when I am at rest and suspect that there is a problem with the way my heart responds to changes in blood pressure. The doctor was very dismissive and said they are just panic attacks but the palpitations are not accompanied by anxiety or panic, I am a very laid back person. To make an attempt at monitoring this problem I bought a pulsemeter and managed to catch one of these attacks.
My weight is 101kg and I am 172cm high, I am 32 years old. Two weeks ago I had my blood pressure measured at 123/80 but a couple of days ago it was measured at 160/100. I would like to lose my excess weight but these palpatations make me very nervous about exercising. I have not drank alcohol, tea, coffee or smoked tobacco for around 10 years. I am also vegetarian but do eat seafood.
My doctor does not seem to think that the 'flatline' pulse has any relevance but it does not seem very common and I suspect it does have some significance.
Is there any conclusion that can be drawn from these results?
