What Causes Heart Palpitations While Sitting Or Standing?

I don't understand why recently, my heart will start pounding fast and hard while I'm sitting up or standing. It happens randomly. I'll be fine one moment and then the next it feels like I'm having a panic attack.
I'm not doing anything physically exhausting or mentally exhausting.

Psychiatrist,  's  Response
Hello thanks for asking from HCM for your health related queries

I can understand your concern. Sudden onset episodes of palpitations while standing or sitting could possible be occurring due to some anxiety attacks. Some medical conditions like Hyperthyroidism, Iron deficiency anaemia, cardiac arrhythmia, B12 deficiency should be ruled out before making the diagnosis of anxiety. Visit a doctor to rule out these conditions. In anxiety symptoms medicines like Propranolol, Atenolol etc has been found to be useful. Some times low dose benzodiazepines as Clonazepam, Alprazolam etc are used for symptomatic relief. Apart from this SSRIs or SNRIs are drugs of choice in anxiety. Visit a psychiatrist for evaluation and for prescription of these drugs.

Thanks, I hope this helps you.

Take care
