Understanding EKGs?


Hello all,

I am reviewing the cardiovascular system for the start of my second year in 2 short weeks....where did the summer GO??? What a nice break it was, but back to the grind.

I am going through my notes on cardiology and need some help with understanding/interpreting EKGs? I have limited experience with the visual aspect of the tracing, but do know what the P, QRS and T represent, lol. Is there any easy way to GET this? If so, I would truly appreciate it?

found a new ekg tutorial today that many of you might like.

http://learn.sdstate.edu/nursing/ecg.htm - cardiac arrhythmias. a 66-page slide show presentation from dr. gloria craig at south dakota state university school of nursing. this is a very nice, simple explanation of the ekg with corresponding egk tracings. there are animations of the electrical conduction pathway for the various arrhythmias to help show what is going on to create the ekg tracing you see on paper. this is a very nice tutorial that addresses the normal sinus rhythm, sinus bradycardia and tachycardia, premature atrial contractions,atrial tachycardia, atrial flutter, atrial fibrillation, premature junctional contractions, junctional tachycardia, first, second and third degree blocks, premature ventricular contractions (pvcs), ventricular tachycardia, ventricular fibrillation and asystole.
