What is the purpose of obtaining a recent EKG during pre-sedation assessment?

The purpose of obtaining a recent EKG during pre-sedation assessment is primarily to assess for myocardial injury risk. A recent EKG can provide valuable information about the heart's electrical activity and functionality, helping to identify any underlying cardiac conditions that could increase the risk of complications during sedation, such as arrhythmias, ischemia, or other forms of myocardial injury. Understanding these risks is critical to ensure patient safety before proceeding with sedative medications.

While other aspects, such as evaluating cardiac history and verifying medication compliance, may also contribute to the overall assessment, they do not specifically address the immediate concerns related to the heart's condition that could impact perioperative safety. The most urgent concern is the identification of any potential heart issues that might put the patient at greater risk during moderate sedation. Thus, focusing on myocardial injury risk makes the assessment of a recent EKG vital in the pre-sedation process.
