An Urban Experience
Ventricular Tachycardia: The primary rhythm is ventricular with rates >100bpm. There are no associated p-waves with the qrs complexes, and the qrs complexes are wide and bizarre. Systemic causes are more common than primary myocardial disease processes. Any disease process resulting in ventricular myocardial hypoxemia can cause ventricular tachycardia. Systemic causes are more common than primary myocardial disease processes in emergent patients.
VENTICULAR TACHYARRHYTHMIAS (VT)
Ventricular Premature Contraction (VPC): The primary rhythm is a sinus rhythm, and intermittent VPCs occur. The abnormal contraction is wide and bizarre, and not associated with any p-wave. There may be a pulse de cit associated with the contraction. When multiform VPCs exist, there is a greater chance for ventricular tachycardia and  brillation. Any disease process resulting in ventricular myocardial hypoxemia can cause VPCs. Systemic causes are more common than primary myocardial disease processes in emergent patients. Occasionally they occur in normal hearts without clinical signi cance.

Accelerated Idioventricular Rhythm (AIR): An idioventricular rhythm under autonomic in uence
that breaks through a sinus rhythm at a slightly faster rate than the sinus rate. Typically, it emerges when a respiratory sinus arrhythmia slows down during inhalation and disappears when the rate increases again during exhalation. Rates of up to 180 bpm may be seen. There are no perfusion abnormalities associated with the rhythm and it requires no treatment.
