ECG FINDINGS(SEEFIGURE1.16)
■ Regular wide complex tachycardia
■ Inappropriately concordant QRS complexes across the precordial leads
■ AV dissociation
■ Fusion complexes
DIFFERENTIAL
■ VT must be differentiated from SVT with aberrant conduction.
■ An approach using a combination of historical clues, general ECG char-
acteristics, and the Brugada ECG criteria (see Table 1.8) will diagnose VT
with reasonable accuracy.
TREATMENT
■ Pulseless→immediate cardioversion. See “Management of Cardiac Arrest.”
■ Unstable →cardioversion.
■ Synchronized
■ Start with 100J
■ Sedation, if possible

FIGURE 1.16. Ventricular tachycardia.
In the patient with prior MI,
wide complex tachycardia is
nearly always VT.
When in doubt, treat any wide
complex tachycardia as
ventricular tachycardia!
