Palpitations: Studies show palpitations, the unpleasant awareness of a "forceful, rapid or irregular" heartbeat are usually benign however can sometimes indicate an underlying arrhythmia. Personal or family (not in-law) history of sudden death, syncope, arrhythmia, structural heart disease, EKG findings like long QT syndrome are some indicators to pursue a workup. Often women disproportionately dx'd w/ anxiety.
