I consider myself to be an anxious individual. I have had episodes of sudden, spontaneous elevation in heart rate even whilst not doing anything strenuous like exercise. I guess you could say its like having a palpitation cos I can sometimes feel the elevation and thumping of my heart when it happens. They feel regular in rate. I normally do deep breathing exercises and they go away though the fright from the experience doesnt. I have had ecgs and seen my general practitioner. My bloods, including thyroid, cholesterol, haemaglobin, white cell count, calcium, potassium, sodium are all normal. Blood glucose ok. Im having a cardiac 24 hrs at the end of the month. My dr says he thinks its stress/anxiety. Sometimes i get symptoms 3 times a week. I have a stressful job but my home life is good. Since my blood tests and ecgs are normal, as a 32 year old who doesnt smoke, drinks sometimes, and exercises regularly should I be worried.
Hello, It's a very common problem and you underwent evaluation, so likelihood of any serious illness is less. So I think you should not worry about it. However, whenever you get such palpitations, just count your pulse rate or heart rate and note it down. We will get additional idea about the cause from pulse rate.  So likely it's all due to anxiety.  Continue breathing exercises and yoga. Hope this helps you and get back if you have any doubts.
