Terminology 315 - Ventricular Rhythms
Part 1
Regardless of rhythm category, morphology of waveforms and pattern of occurrence are important aspects to include in an accurate interpretation.
Unifocal – abnormal complexes are of the same shape
Multifocal – abnormal complexes are of two or more different shapes. This indicates the impulse causing the PVC’s are coming from different locations.
Bigeminy – abnormal complexes occur every second complex
Trigeminy– abnormal complexes occur every third complex
Part 2
Regardless of rhythm category, morphology of waveforms and pattern of occurrence are important aspects to include in an accurate interpretation.
Quadrigeminy– abnormal complexes occur every fourth complex
Couplet – Two PVC’s together
Run of Ventricular Tachycardia
(V Tach) – Three or more PVC’s in a row at a rate of 100 bpm or greater. Also known as Triplet PVC’s or Salvo PVC’s
