11. What are the common causes of ST-segment elevation?
12. What are signs of ischemia on a 12-lead EKG?
Answer (2)
A 12-lead EKG measures the heart's electrical activity using 10 electrodes positioned on the body. It is crucial for diagnosing various heart conditions, including myocardial infarction and ischemia. Understanding how leads are placed and what changes to look for helps in effective interpretation of the EKG results. ;
A 12-lead EKG is crucial for measuring the heart's electrical activity and diagnosing conditions like myocardial infarction. It uses 10 electrodes placed on the body, capturing various heart views. Understanding lead placement and associated changes allows for effective interpretation of EKG results.
