Why heart rate becomes irregular? - #12402
I am really worried about something I've been experiencing lately. My heart rate has been super irregular. Like, sometimes it's racing, and other times it just feels all over the place? I thought it might just be stress because I've been juggling work and family stuff, but then I started feeling kinda dizzy and out of breath too. I went to my doc, and they did an EKG, which showed that my heart rate can really jump from fast to slow. It's freaky! I keep asking myself, why heart rate becomes irregular? Is it really just stress, or could there be something deeper? I've tried changing my diet and even started exercising more, but the irregularity is still there. It's especially noticeable during the night when I'm trying to relax, and my heart feels like it’s racing! I can't help but wonder if this is serious. Why heart rate becomes irregular for some and not others? Would love to hear from anyone who's gone through something similar. Do you think I should ask for more tests, or is it normal for these things to happen sometimes? Thanks for reading!

Doctors’ responses
Irregular heart rates, or arrhythmias, can be caused by a variety of underlying factors, and it’s understandable to be concerned, especially given the symptoms you describe. While stress can indeed be a trigger, it’s not the sole reason for irregular heartbeats. An irregular heart rate can stem from issues like electrolyte imbalances, hormonal changes, issues with the heart’s electrical system, and other systemic illnesses like thyroid problems. It’s also possible that certain medications, alcohol, caffeine, or drug use could be contributing factors. The dizziness and breathlessness you mention are signals that something more than occasional stress might be at play. These symptoms make it very important to continue pursuing a clear diagnosis. Given that your EKG showed notable irregularity, it would be wise to follow up with a cardiologist for further evaluation. They might recommend tests like a Holter monitor, which records your heart’s activity over a longer period, or an echocardiogram to assess the structure of your heart. If these symptoms are accompanied by fainting, severe shortness of breath, or chest pain, seek immediate medical attention as these could be signs of a serious condition. While stress reduction, diet, and exercise are great lifestyle changes, they may not directly address the root of an arrhythmia. Until you have a clearer understanding of what’s causing your symptoms, continue to monitor your symptoms and share any new changes with your healthcare provider. Also, attempt to avoid known triggers like caffeine or heavy exercise until further advice. Always prioritize getting any sudden, severe, or worsening symptoms checked out immediately.
