My heart rate's been fluctuating quickly 80-170bpm for a week. ekg and labs normal, mitral valve prolapse on echo. burning in inner ears today. ideas?

Do you have SVT?: It you have supraventricular tachycardia diagnosed cilnically or on holter monitor, there are a variety of ways to approach it -- i used to have it (and mild prolapse on echo) and found that simply staying in really good aerobic shape worked better than meds, as the textbooks confirm. This is one for a good general physician or a caridologist.

Test rhythm problems: You almost certainly have rhythm problems probably atrial arrhythmias. You will need to see a cardiologist and have holter monitoring, which is usually attaching a recorder to you and storing all the rhythms for analysis later.
