My husband is 48 years old. He began feeling dizzy/lightheaded and was just about to black out.  We have a blood pressure monitor at home, so it read 108/52, pulse 73. Should he be concerned? He takes high blood pressure medicine every morning. He has not been like this before. He also had a pain in his  left ARM that lasted 25 to 20 minutes. I intend to take his blood pressure again in  30 minutes.
Hello, If symptoms persist, it is better to consult a physician and get evaluated.  Detailed evaluation is required. Hope I have answered your query. Let me know if I can assist you further.
