A kind man who had been interpreting ECGs for over 25 years taught the elective. We all had to read <em>Rapid Interpretation of EKGs<\/em> by Dale Dubin, and each day we spent hours going through real ECGs and trying to interpret them using the teacher&#8217;s systematic method. Then, we compared our interpretation to his official reading. And so it went, over and over, daily for a month. This was probably the most helpful part of my clerkship experience.<\/h6>\n\n\n\n<hr class=\"wp-block-separator\" \/>\n\n\n\n<p>However, by the time I got to my internal medicine internship, I remembered roughly one-fourth of what I had learned in the elective. I felt a pressing need to have my ECG reading skills down pat, especially with CCU and ICU rotations looming and the eventuality of leading my own team on the medical floors.<\/p>\n\n\n\n<p>A friend of mine who was already in his emergency medicine residency recommended his study method. Since he read numerous ECGs every day, I followed his advice and stocked up on some additional books:<\/p>\n\n\n\n<h6 class=\"wp-block-heading\">1. <em><a rel=\"noreferrer noopener\" aria-label=\" (opens in a new tab)\" href=\"https:\/\/www.amazon.com\/ECGs-Emergency-Physician-Amal-Mattu\/dp\/0727916548\/ref=sr_1_1?s=books&amp;ie=UTF8&amp;qid=1475154680&amp;sr=1-1&amp;keywords=ECGs+for+the+emergency+physician\" target=\"_blank\">ECGs for the Emergency Physician 1<\/a><\/em> by Amal Mattu and William Brady\u00a0<\/h6>\n\n\n\n<p><strong>How to use the book<\/strong>:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Look at each ECG with its clinical scenario.<\/li><li>Mentally note what is happening in the ECG (i.e., the rate and rhythm, any ST changes, how the T waves look).<\/li><li>Turn to the back of the book and read the ECG interpretation paragraph.<\/li><li>Take the main points from the&nbsp;<span>ECG interpretation<\/span> and add these notes to the initial ECG.<\/li><li>Review 5 to 10 ECGs per day.

You&#8217;ll forget some of what you learned in the earlier reading, but this is important. Forgetting ultimately leads to a better understanding.

For CCU patients, discuss the ECG readings with the cardiologist and note the characteristics to look out for. Follow up on the official cardiologist reading of all ECGs. If a patient goes to the electrophysiology lab, find out how other people interpreted their ECGs. For patients in the CCU or ICU or on the cardiology floors who have had MIs, compare the ECGs from their presentation in the ED with their ECGs post-treatment. This habit\u2014the follow-up\u2014is the fastest, least expensive way to become an expert.
