[|Human|] Hello, im 25 years old and a male. I was just outside shoveling snow when i noticed my legs felt a little bit weak and shaky. I was almost finished so i got done and came inside to take a shower. While in the shower i noticed my heart rate seemed a little bit fast, and my head seems a wee bit foggy. Im overweight, 6 foot 1 and 250 pounds but i am scared that this is something very serious and i should consult an ER because i do not want anything crazy to happen. Please let me know what you think.
[|AI|]  Hi, Actually I don't think you have to be worried unless it happens constantly, or repeatedly it may happen due to stress, effort, cardiac, respiratory causes it even happens with large amounts of caffeine in tea, coffee and chocolates. If so, you have to ask your physician for ECG and don't hesitate. Please consider positive feedback if the information is helpful. Hope I have answered your query. Any further clarifications feel free to ask.
