• In monomorphic VT, QRS complexes have the same shape and amplitude.
• It originates from a single focus and is identical from beat to beat.

Rate: 100–250 bpm

Rhythm: Regular

P Waves: None or not associated with the QRS

PR Interval: None

QRS: Wide (greater than 0.10 sec), bizarre appearance

Clinical Tip: It is important to confirm the presence or absence of pulses because monomorphic VT may be perfusing or nonperfusing.

Clinical Tip: Monomorphic VT will probably deteriorate into VF or unstable VT if sustained and not treated.
