Notes
![Page 18: Ecg or ekg sample strips (MS Cardiovascular)](https://reader035.vdocument.in/reader035/viewer/2022081505/554b3882b4c905ff268b45e0/html5/thumbnails/18.jpg)

Rate Characterized by Atrial rate usually normal and faster than ventricular rate
P Wave Normal shape and size, may appear within QRS complexes
PR Interval Absent: the atria and ventricles beat independently.
QRS Normal, but wide if junctional escape focus
