Can stress cause rapid heart rate and dizziness?
Patient: I have rapid heart rate and am dizzy lately.  My heart rate goes up to 132 when I am walking around.  I am dizzy when I sit.  I went to Meijer and it happened there my blood pressure was 146/93.  108 heart rate.  I have never had high blood pressure.  I have had the same thing before and went to the E..R. where they said I was fine.  I am under a ton of stress right now, could that be the reason Doctor: hi..thanks for the query. May I know what is your age & whether you are on any long term medications or received a short course of medications recently? Assuming you have neither of these, first thing we need is to conclusively rule out a condition named arrhythmia which occurs due to dysregulated firing of hearts rhythm generator or pace maker resulting in symptoms of sudden onset pounding heart, lightheadedness or dizziness. This can be ruled out by a ecg. Once arrhythmia is ruled out; what we are seeing is essentially anxiety either situational or occurring suddenly. This can be easily taken care of by giving sos clonazepam/etizolam (benzodizepines) and depending upon cause of your anxiety SSRI group drug like sertraline, escitalram which will take care of your anxiety symptoms altogether. Hence dont worry, consult your primary care doctor & I am sure you will be fine in no time!! good luck
