Hi doctor! I am carrying on level 1 heart failure. Recently, I often have symptoms of headache, shortness of breath, irregular heartbeat, fatigue.

I often have difficulty breathing when the weather is too hot, often have symptoms of heart palpitations, heart rate up at an unstable rate. The doctor asked me if I had trouble breathing, my heart beat faster when the weather was hot, is it okay? I went to the doctor and everything was normal. Thank you.
