Digital Seminar


It’s two o’clock on a Sunday morning and you are the Charge Nurse on a 24-bed telemetry/Med Surg Unit. Mrs. J, in room # 312, is on telemetry and her low heart rate monitor alarm goes off.

You assess her and note she is hemodynamically compromised with a BP of 74/42, cool and clammy skin and complaints of dizziness. What is the rhythm strip telling us about the patient? Do you know what do next?

Know what clues to look for and what steps to take by attending this information-packed seminar. Leave with a clear understanding of and be able to recognize basic and advanced cardiac dysrhythmias. Learn the systematic approach to EKG interpretation, with advanced skills in differentiating ischemia from infarct on the EKG, identifying STEMI imposters and many other causes of abnormal EKGs. Use these skills to improve patient outcomes for patients like Mrs. J and others you see in practice by being able to anticipate treatments and complications.




NOTE: Tuition includes one free CE Certificate (participant will be able to print the certificate of completion after completing and passing the on-line post-test evaluation).
