New onset A-Fib may present with which symptom listed in the material?

Explanation:
New onset atrial fibrillation often triggers a rapid, irregular heartbeat because the atria are quivering and the ventricles respond with a fast, irregular rhythm. This rapid ventricular response manifests most clearly as tachycardia, a direct sign of AFib onset that EMT materials commonly list. While dizziness, fatigue, and nausea can occur from reduced cardiac output or other factors, they are non-specific. The key feature you’d expect to find is a fast, irregular pulse, and an ECG would typically show an irregularly irregular rhythm without discrete P waves, confirming AFib with rapid ventricular response.
