I suffer with palpitations everyday.   I have seen a doctor and after testing and two visits I was told it was not a concern.   Recently I read that palpitations can cause blood to pool thus creating blood clots and a possible stroke.  Is this correct and should I be concerned or see a cardiologist?
Hello! Thank you for asking on Chat Doctor! Regarding your concern, I would explain that only some types of cardiac arrhythmia could cause blood clots in the heart, leading to cardiac embolism and possible stroke. But you should know that many cardiac arrhythmias which are associated with palpitations are not harmful. I would recommend consulting with your GP for a careful physical examination, a chest x-ray, a resting ECG and some blood lab tests (complete blood count, blood electrolytes, fasting glucose, thyroid hormone levels, kidney and liver function tests, etc.). An ambulatory 24-48 hours ECG monitoring and a cardiac ultrasound would be necessary to examine your heart structure and function and exclude possible cardiac arrhythmia. Hope to have been helpful!
