| A previous work-up had discovered frequent premature ventricular complexes and runs of bigeminy on a Holter monitor examination. |
|
| Data collection included counts of the number of premature contractions, including PVCs and those in alternating rhythms such as bigeminy and trigeminy, during the first three hours post infarction. |
|
| Nonconducted atrial bigeminy refers to the presence of electrical signals originating from atrial foci outside the sinus node which are not transmitted to the ventricle. |
