Had 5-day holter monitor. had palpitations. doc gave reason, but said not serious. what could cause palps every couple minutes if not harmful?

Cause unknown: This is a very common complaint and a specific cause is rarely identified. Although this can be frustrating, this typically carries no risks of significant medical problems. Treatment is not helpful and can even cause harm. Of course I have not seen the monitor, but am taking your doctor's analysis at face value.

Need more info: The most likely cause are pvcs. By themselves, they are generally not harmful. If you continue to have annoying symptoms, ask to see a cardiac electrophysiologist. They may be able to prescribe medicine that could control your symptoms or offer a procedure to fix the problem.

Palpitation treat: Treatments include not using caffeine, alcohol , street drugs, smoking and other stimulant substances. Try to learn meditation and other calming techniques, cut out herbal substances, cough and cold medicines, nutritional supplements, see your doctor to be sure no direct heart problem and for treatment if the basics above don't help.
