Yes it can, EK. Heart palpitations are a very common symptom that start in perimenopause or beyond and seem to be related to changes in our estrogen levels. As long as they are not associated with pain, do not make you short of breath, and don't cause any sensations that radiate elsewhere in your body like down your arm/to your jaw/to your back, they are probably a variation of normal that comes with menopause. Especially since you had the cardiac work-up, I'd be reassured.
Hope this is helpful,
