I've also experienced heart palpitations and other symptoms. Recently I was diagnosed with a trivial leak in my aortic valve. I believe this is related to the overdose. We would guess that symptoms you experienced right after the medication was administered relate directly to the overdose of the anesthetic. We cannot find a reference for a direct correlation between the medication reaction and aortic valve regurgitation.
Palpitations are a symptom of aortic regurgitation.
Tremors are not related to the aortic valve regurgitation. Try to relieve your palpitations and other symptoms of the aortic valve leakage by following your physician's regimen of care. Check the calendar.
