Answer:
When the level of certain electrolytes in the blood gets low, this can cause more
extra heart beats (premature atrial complexes, premature ventricular complexes) and
also promote more abnormal heart rhythm, especially if you have an underlying heart
rhythm problem. This can lead to you feeling palpitations that can be characterized
as a "quivering heart." More palpitations can certainly be more annoying, but it does
not necessarily mean that it is dangerous to you. Usually, if you have no prior history
of heart problems, the palpitations are more of an annoyance.
If the palpitations bother you enough, then a doctor can order a heart rhythm monitor that you can wear at home. This will record what your rhythm is doing when you are having palpitations and help you and your doctor decide what to do. The most common electrolytes that can cause palpitations when they get low are potassium and magnesium. I would caution against taking extra supplements of electrolytes (or minerals) without consulting your doctor, however, because if your kidneys are not able to get rid of the extra electrolytes in your blood, too high a level of certain electrolytes can be life-threatening.
