Palpitation: You might need a test called holter monitor. This text your heart ekg for 24 hours.

Dizziness : Need to wear a heart monitor to see what is occurring electrically with your heart and make sure there are no arrhythmias, skipped beats or extra beats that would correlate with your symptoms. A primary care physician or a cardiologist would be able to evaluate this for you. Avoid caffeine and stimants like decongestants. Maintain adequate hydration.
