| In this example, each normal beat is followed by a premature ventricular contraction occurring in a bigeminal rhythm. |
|
| Because the bigeminal episodes are still occurring and I was still concerned, I obtained copies of my holter and event monitor strips. |
|
| Sinus rhythm, with bigeminal premature ventricular contractions, and a ventricular couplet. |
|
| The building blocks of the proposed detector include ectopic beat filtering, bigeminal suppression, characterization of RR interval irregularity, and signal fusion. |
