Normal Ekg Diagram. This chapter will focus on the ecg waves in terms of morphology. This is arguably one of the most important chapters throughout this course.
Rhythm 10 variation in rr intervals rate 60 99bpm cardiac axis 30 90 p waves 02 03mv 006 012s upright in i ii avf v2 v6 inverted in avr varies in iii avlsinus origin pr interval 012 02s q waves small in i ii avl v5 v6 qrs complex 012s st segment. Each small square represents 004 seconds each large square represents 02 seconds 5 large squares 1 second 300 large squares 1 minute how the 12 lead ecg works. The normal ecg the normal ecg will display these characteristics.
Normal sinus rhythm each p wave is followed by a qrs p waves normal for the subject p wave rate 60 100 bpm with 10 variation rate.
Normal ecg normal adult 12 lead ecg the diagnosis of the normal electrocardiogram is made by excluding any recognised abnormality. Look carefully and memorize the regular pqrst shape heart rate normally should be between 60 100 beatsmin now. Provides information on atrial depolarization and the p wave ventricular depolarization and the qrs complex ventricular repolarization and the t wave as. Have a look on the most common abnormalities always compare them to the normal sinus rhythm bradycardia the heart beats are slow.
