ECG Answer for ~ April 22nd 2017
Sinus Arrhythmia. Heart Rate 48-75/min. QRS axis:+65
PR: 100ms QRS: 120ms QT/QTc: 434/437
LVH. ST/T wave changes.
Comment: Sinus Arrhythmia: sinus p wave before each QRS, irregular rhythm with gradual change in PP interval, spontaneous change in CL >100%, varies with respiration and vagal tone. WPW: short PR with ventricular pre-excitation(delta wave). LVH: R V6= 50mm (n<26mm). Abnormal repolarisation: ST changes with T wave inversion across praecordial leads
This child has WPW associated with LV noncompaction.
