<human>: Hi my husband has been experiencing fatigue, fast heart rate at times when sitting, pain or numbness in left arm, slight chest pains (left side) slight dizziness at times this has been going on for about a month , he also drinks everday but hardly smokes
<bot>: Hello, I understand your concern and would explain that his symptoms could be related to anxiety.  Anyway, before coming to this conclusion, I would recommend performing some tests in order to exclude other possible causes: -a resting ECG and cardiac ultrasound- a chest X-ray study-complete blood count for anemia-fasting glucose-blood electrolytes.  An exercise cardiac stress test may be needed.  You should discuss with your doctor on the above tests.  Hope I have answered your query. Let me know if I can assist you further.
