Can a heart problem cause severe weakness and dizziness? i have had chest pain and fluttering that lasts 2 to 3 mins then the weakness starts..

Absolutely: This can be a problem with the rhythm of the heart's beating. If your heart isn't working properly, your body & brain won't get the oxygen and nutrients needed to function properly. You should report to your primary care provider or cardiologist for an examination and/or testing.

Yes: Yes. See MD or go to ER for exam. Can result in fatal arrhythmia.
