"I was experiencing lightheaded and odd pounding in my chest several times a day.  Holter study confirmed that my heart palpitations were frequent PVC runs of between 3 and 9 premature ventricular contractions in a row a couple of times an hour.  After starting ONE 3.125 Carvedilol at night, the PVCs were reduced to an occasional once per week or less noticeable event.  Increasing the dose to two 3.125 per day did not improve the symptoms any further but did significantly lower my heart rate to an unacceptable level.  Due to frequent endurance training and a resting heart rate already in the low 40s, the extra lowering of the heart rate was not acceptable.  The decision was made to stay on a single 3.125 nightly."
