56 year old female patient with mitral regurgitation, prosthetic mitral valve endocarditis, and pneumonia.
Rhythm analysis indicates sinus tachycardia at over 100 bpm. Several short runs of ventricular tachycardia or VTach are seen. First degree heart block is also present.
This encounter highlights several short runs of ventricular tachycardia, a dangerous rhythm that can lead to ventricular fibrillation (VFib) and cardiac arrest. VTach is identified as three or more PVCs in a row, with a rate higher than 120 bpm. Short runs of VTach such as the one seen here are not life threatening, and typically self resolve quickly. However, sustained ventricular tachycardia causes extremely low cardiac output and blood pressure. Sustained VTach may require cardioversion or antiarrhythmic drugs.
