Submitted by Dr. Dennis Cho (@DennisCho), written by Jesse McLaren A 70-year-old with no cardiac history presented with 2 hours of chest pain radiating to the neck, associated with shortness of breath. What do you think? There’s normal sinus rhythm, first-degree AV block, normal axis and voltages. R wave progression is abnormal: there are Q waves in aVL/V2-3 and loss of R wave in V2.

With the ongoing forcing of participation in Maintenance of Certification (MOC) of US physicians by the American Board of Medical Specialties (ABMS)and its 24 member boards, we are seeing the slow demise of physician-selected Continuing Medical Education (CME) in America. Attendance at specialty society meetings is at an all-time low.

There are 4 quizzes here on OMI ECG diagnosis: Beginner Novice Intermediate Advanced The first link on the page is to an ECG guide as a primer on OMI ECG diagnosis. These quizzes were written by Gregory Yates (an "FY 2 doctor" in the UK), Maddy Kahle (who is just finishing her 4th year of medical school at the U of MN), and aided by Romi Lee (another U of MN med student).

Objective American Indians and Alaska Natives (AI/ANs) are an understudied population at high risk for cardiovascular diseases (CVDs); little is known about contextual factors contributing to CVDs in AI/ANs. This study examined the association of Life’s Simple 7 (LS7) factors and social determinants of health (SDH) with CVD outcomes in a nationally representative sample of AI/ANs.

I was asked for my interpretation of this tracing. No history was provided. How would YOU interpret this long lead II rhythm strip? Are the different-looking beats PVCs or supraventricular impulses conducted with aberration? — or — Something else? Figure-1: The long lead II rhythm strip for today’s case. No history was available. ( To improve visualization — I've digitized the original ECG using PMcardio ).

Objective The incidence of infective endocarditis (IE) is increasing, as is the insertion of prosthetic heart valves. We aimed to examine nationwide temporal trends in the incidence of IE in patients with a prosthetic heart valve in Denmark from 1999 to 2018. Methods Using the Danish nationwide registries, we identified patients who underwent heart valve implantation (for other reasons than IE) between 1999 and 2018.

I was reading EKGs on the system and came across this one. I am always looking for EKGs that show either subtle OMI or OMI mimics. Which did I think this was? I suspected that this was a mimic. It is hard to say why. There is "inferior" ST depression, reciprocal to high lateral ST Elevation. The precordial leads have ST Elevation but also high voltage and look like possible LVH.

Objective Cardiac surgery may cause temporarily impaired ventricular performance and myocardial injury. We aim to characterise the response to perioperative injury for patients undergoing repair or pulmonary valve replacement (PVR) for tetralogy of Fallot (ToF). Methods We enrolled children undergoing ToF repair or PVR from four tertiary centres in a prospective observational study.
