Question

Work with the following EKG strip for following questions: The EKG strip above is indicative of STEMI: ST-segment elevated myocardial infraction. Another common sign of acute Mi is wide QRS complex. Research both pathological EKG signs and confirm their presence (or not) on this EKG strip. Furthermore, every EKG has universal voltage and time scale for interpretation of heart rate/period/amount of polarization etc. Again, learn how to apply this scale and answer following questions. What is the heart rate of this patient? Is the heart in a normal sinus rhythm? What part of heart is affected? Design a new method to diagnose the condition depicted above would like to see original bioengineering approach.

Explanation / Answer

The heart rate will be 150 beats/min, as the RR interval is2 big boxes, duration 0.4 sec, as 1 big box is 0.2 sec.

No, it is not a normal sinus rhythm. Sinus rhythm is one where the P wave is upright in leads I & II and inverted in aVR. it is not the case here.

Left Ventricle

There is presence of STEMI and not widened QRS complex
