76 year old male patient with history of smoking monitored during gastrectomy and duodenostomy.
Rhythm analysis indicates sinus tachycardia with heavy ectopy in the form of PACs. Runs of Supraventricular Tachycardia (SVT) can be seen as a result of this activity.
This encounter contains an underlying rhythm of sinus tachycardia, indicated by the regular rhythm, high rate, and the presence of P waves (although they are difficult to see). Premature Atrial Complexes (PACs) are occurring frequently, leading to short runs of Supraventricular Tachycardia (SVT), a rhythm identified by an extremely fast rate and sudden onset. P waves cannot be easily identified in SVT, as they are often buried in T waves.
