This high impact lecture reviews the critical EKG findings that every EMS provider must quickly recognize to prevent life threatening delays in care. EKGs can be tricky to diagnosis or interpret especially on the fly while in the back of moving ambulance. Several of the lethal arrhythmias cannot be incorrectly interpreted and can be lethal to your patient. Participants will learn to identify key patterns such as STEMI equivalents, lethal arrhythmias, electrical emergencies, and subtle but high-risk abnormalities often overlooked in the field. The session focuses on rapid interpretation, clinical implications, and immediate prehospital actions that can significantly improve patient outcomes. When you are incorrect, the patient pays the price.
