We just started our cardiac module. I was given a random EKG strip from the hospital to measure/interpret Lead II and am having a devil of a time deciphering it. It doesn’t look clear cut like any of the rhythms we’ve studied in class. I know how to measure intervals, but I’m having trouble even figuring out the basics, such as:
1- where exactly does the p wave start ?
2- Is the t wave inverted?
3- What is the notched downward deflection between the QRS? Could that be an inverted p wave?
Any help in figuring this out would be appreciated.
Thank you everyone for the responses! I was finally able to get a moment to sit with a telemetry tech for some guidance and they confirmed your findings - ventricular bigeminy and the waveforms between are small from poor conduction or electrode placement. I agree that this assignment is a ridiculous way to have a beginner learn.. so I am extra appreciative of you all taking the time to help!
LOL, horrible strip to "learn" It is tricky. I would venture to say first degree AV block with ventricular bigeminy. Yes, the T-waves are inverted, I believe this is called a "ventricular strain" pattern common with ventricular hypertrophy. There is a gradual downsloping of the t-wave and rapid up sloping. This is a ridiculous strip to learn from if just starting.
