So my left atrium size is 5.6 cm, and my doctor says my heart is alright, but I'm not sure how that is possible. On top of it, I'm having trouble with dyspnea when I exert myself. Could someone help explain what's going on?

It is possible for your doctor to determine that your heart is functioning normally despite the enlarged left atrium (LA) size. However, experiencing dyspnea on exertion is a concerning symptom that should be further evaluated. In this case, you may benefit from medication such as a beta-blocker like Metoprolol (25-50 mg daily) to help with your symptoms. Additionally, a diuretic like Furosemide (20-40 mg daily) may be prescribed to reduce fluid buildup and alleviate the dyspnea. It is important to follow up with your doctor for further evaluation and management.

I'm a software engineer and I'm generally in good health. My BMI is normal and my blood pressure is fine too. But I've noticed that my resting heart rate is always over 90 and it's kind of unsettling. I've recently started working out to stay fit and while I don't feel any discomfort, that number still worries me. Should I be concerned about it? What could be causing this and is there a way to bring it down to a normal range?

I've been feeling really off lately. Sometimes I feel like I can't breathe properly, and I start sweating. I checked my blood pressure and pulse, and they seem normalBP was 12070, and pulse rate was 73. But for the past few nights especially, my heart feels like it's racing. I go to the gym regularly, I don't smoke, but my job at an MNC is pretty stressful. Could stress be causing this, or should I be worried about something else?
