Palpitations, and elevated heart rate are symptoms that nearly everyone experiences at some point in their life. Most often, “skipped beats” or the perceived irregularity in cardiac rhythm is benign and may be the result of stress, poor sleep patterns or even increased consumption of dietary stimulatants (e.g. Caffeinated beverages, alcohol even in modest amounts). With increased age however, this may also represent a potentially very serious rhythm disorder known as atrial fibrillation.
