Echocardiography is fundamental to the understanding and practice of cardiology. Traditionally, echocardiography is taught at the postgraduate level, mainly during cardiology fellowship. 1 The creation of hand-held ultrasound has made ultrasound learning more popular and expanded to residency and medical school levels. 2 Small studies suggested that learning cardiac ultrasound and/or point-of-care ultrasound during medical school was feasible [3][4][5][6] and can help improve understanding of cardiac physiology and anatomy 7,8 as well as physical exam skills. 3 However, cohesive cardiac ultrasound curricula are lacking in medical school. To date, there is no large study to evaluate

There is growing evidence that patients with severe systemic illness from coronavirus disease 2019 (COVID-19) are at risk for developing a variety of cardiac arrhythmias. Less is known about patients with milder symptoms. Here, we report on the case of a 62-year-old male, admitted to the hospital following an episode of syncope, who experienced multiple episodes of cardiac arrest due to asystole lasting up to 30 seconds. History revealed a recent asymptomatic COVID-19 infection, and recurrent episodes of prolonged asystole necessitated permanent pacemaker placement. To our knowledge, this is the first report of an asymptomatic COVID-19 patient experiencing prolonged asystole. Cardiac arrhythmias in asymptomatic or oligosymptomatic COVID-19 patients may be underestimated.

Background At most institutions, internal medicine residents struggle with balancing clinical duties and learning opportunities, particularly during busy cardiology ward rotations. To improve learning experiences for residents, we helped develop a cardiology handbook app to supplement cardiology education. Objective The aim of this study was to report the development, implementation, and preliminary impact of the Krannert Cardiology Handbook app on graduate medical education. Methods In June 2017, 122 residents at Indiana University were invited to download the digital handbook in the Krannert app. The Krannert app featured a total of 13 chapters written by cardiology fellows and faculty at Indiana University. Residents were surveyed on their self-reported improvement in cardiology knowledge and level of satisfaction after using the Krannert app. Residents were also surveyed regarding their preference for a digital handbook app versus a paper handbook. Results Of the 122 residents, 38 trainees (31.1%) participated in survey evaluations. Among all respondents, 31 app users (82%) reported that the app helped improve their cardiology knowledge base. The app had an overall favorable response. Conclusions The Krannert app shows promise in augmenting clinical education in cardiology with mobile learning. Future work includes adding new topics, updating the content, and comparing the app to other learning modalities.
