56 year old female patient with mitral regurgitation, prosthetic mitral valve endocarditis, and pneumonia.
Rhythm analysis indicates sinus tachycardia at over 100 bpm. First degree heart block is also present.
This encounter shows a fast rate over 100 bpm, with a regular rhythm and P waves, indicating sinus tachycardia. The extremely long delay between the P wave and QRS indicates first degree heart block. Additionally, ectopy is seen in this encounter, in the form of premature ventricular contractions. These wide, bizarre looking QRS complexes can be caused by both serious conditions such as heart disease, and also external events such as exercise, excessive caffeine, and alcohol.
