What's your assessment and care for a patient who had evidence of a STEMI, but is now pain free?
Article Updated July 31, 2017
As this 12-lead EKG case will demonstrate, it is important to look at the entire picture when responding to a call and to understand why a specific treatment or no treatment at all may be the best option. Please review the following case and offer your thoughts on potential treatments you would initiate for this patient.
Patient presentation: Female having a STEMI is now pain free
ALS1 is dispatched to a rural medical facility to transport a patient diagnosed with an acute coronary syndrome to the closest cath lab, which is about 55 minutes away. Upon arrival, you are briefed on the current status of your patient: She is a 64-year-old diabetic, hypertensive female, who was brought to the facility an hour ago with evidence of a STEMI.
She arrived within 30 minutes of her symptoms' onset and has been treated with aspirin, heparin and thrombolytics for several minutes now. She reports that she is pain-free and actually feels much better.
The patient exhibits no change in her current condition. She denies feeling any chest pain, dizziness, dyspnea, palpitations or any other discomfort. She is alert, conscious and oriented to person, place and time.
Patient's vital signs:
Heart Rate: 84 bpm
Respirations 18 rpm
Blood Pressure: 110/80 mm Hg
SpO2: 98 percent on 3 lpm of oxygen
Past medical history:
Denies any prior cardiac history
No known drug allergies
On the hospital's monitor, you see a normal sinus rhythm without PVCs. After completing the appropriate paperwork and information regarding the patient, you and your partner attach your cardiac monitor monitor, connect her to your portable oxygen cylinder, load her onto the stretcher and attach the IV bags into the stretcher IV pole.
As your patient continues to calmly talk to you en route, you glance at the rhythm monitor casually and notice a rhythm change.
