Emerging ECG Methods for Ischemia Detection

<p>Emerging ECG Methods for Ischemia Detection</p> <p>Guest: Salah Al-Zaiti (<a href='https://twitter.com/al_zaiti'>@al_zaiti</a>)  </p> <p>Hosts: Anthony H. Kashou, M.D. (<a href='https://twitter.com/anthonykashoumd'>@anthonykashoumd</a>)</p> <p>The accuracy of the 12-lead ECG in detecting ischemia will be discussed, as well as the emerging approaches to enhance ECH sensitivity to acute myocardial ischemia. The use of AI for ECG interpretation and how it can help boost the diagnostic yield of the 12-lead ECG for ischemia detection will be reviewed along with the research and future opportunities and recommendations.</p> <p>Joining us today to discuss Emerging ECG Methods for Ischemia Detection is Salah Al-Zaiti, M.D., Associate Professor of Nursing, Emergency Medicine in Cardiology, Vice Chair of Research, at the Dept. of Acute and Tertiary Care at the Univ. of Pittsburgh School of Nursing.</p> <p>Specific topics discussed:</p> <ul><li>The 12-lead ECG is one of the most widely used noninvasive assessments of acute myocardial ischemia in symptomatic patients, namely those with chest pain. However, the ECG remains a suboptimal tool in diagnosing ischemia in this population, requiring the use of numerous diagnostics and assessments. But how accurate exactly is the 12-lead ECG for detecting ischemia? And what are the potential pitfalls of this suboptimal diagnostic accuracy?</li> <li>Let’s go back to the basics then, what are the ECG basis of acute ischemia? In other words, what are the processes and the mechanistic links between diminished coronary blood flow at the myocardial level and potential manifestations on the surface ECG?</li> <li>In your most recent commentary paper on the topic at Journal of Electrocardiology, you discuss four emerging approaches to enhance the ECG sensitivity to acute myocardial ischemia: (1) techniques based on novel ECG signatures of ischemia beyond ST-segment and T wave amplitudes; (2) techniques that maximize the spatial coverage of the ECG; (3) techniques based on ECG imaging; and
