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.

Quadrigeminy– abnormal complexes occur every fourth complex
