a quality assessment of cardiac Auscultation material on youtube
Clinical Cardiology, 2013Co-Authors: Christian F Camm, Nicholas Sunderland, John A CammAbstract:Background: YouTube is a highly utilized Web site that contains a large amount of medical educational material. Although some studies have assessed the education material contained on the Web site, little analysis of cardiology content has been made. This study aimed to assess the quality of videos relating to Heart sounds and murmurs contained on YouTube. Hypothesis: We hypothesized that the quality of video files purporting to provide education on Heart Auscultation would be highly variable. Methods: Videos were searched for using the terms ‘‘Heart sounds,’’ ‘‘Heart murmur,’’ and ‘‘Heart Auscultation.’’ A built-in educational filter was employed, and manual rejection of non-English language and nonrelated videos was undertaken. Remaining videos were analyzed for content, and suitable videos were scored using a purpose-built tool. Results: YouTube search located 3350 videos in total, and of these, 22 were considered suitable for scoring. The average score was 4.07 out of 7 (standard deviation, 1.35). Six videos scored 5.5 or greater and 5 videos scoring 2.5 or less. There was no correlation between video score and YouTube indices of preference (hits, likes, dislikes, or search page). The quality of videos found in this study was highly variable. YouTube indications of preference were of no value in determining the value of video content. Therefore, teaching institutions or professional societies should endeavor to identify and highlight good online teaching resources. Conclusions: YouTube contains many videos relating to cardiac Auscultation, but very few are valuable education resources.

Effect of teaching and type of stethoscope on cardiac auscultatory performance.
American heart journal, 2006Co-Authors: Kasper Iversen, Ane S. Teisner, Morten Dalsgaard, Rasmus Greibe, Hans Bording Timm, Lene Theil Skovgaard, Asbjørn Hróbjartsson, Ø. Copenhagen, S. Copenhagen, K. CopenhagenAbstract:Background Auscultation of the Heart is a routine procedure. It is not known whether auscultatory skills can be improved by teaching or with the use of an advanced stethoscope. Methods This study was a randomized trial with a 2 × 2 factorial design. Seventy-two house officers were randomized to a simple or an advanced stethoscope and to a 4-hour course in Auscultation or no course. The doctors auscultated 20 patients' Hearts and categorized findings as normal or as one or more of 5 categories of Heart diseases. Patients were selected such that 16 had a known Heart disease as well as a corresponding murmur and 4 had no Heart disease or murmur. Auscultatory performance was assessed as concordance with echocardiographic findings and interobserver variation. Results Doctors using the advanced stethoscope diagnosed 35% of the patients correctly, as compared with doctors using the simple stethoscope who did 33% of the patients ( P = .27). Similarly, 34% of the patients were diagnosed correctly by doctors who had received teaching as compared with 33% of those who were by doctors who had received no teaching ( P = .41). The κ values were higher for doctors who had received teaching for aortic stenosis (0.43 vs 0.28, P = .004) and ventricular septum defect (0.07 vs 0.01, P = .003). There was no difference between groups for any other single murmur or for the detection of murmurs as such. Conclusion Heart Auscultation findings were in poor accordance with echocardiographic findings and had high interobserver variation. Neither outcome improved to any important extent with the subjects' use of an advanced stethoscope or attending of a course in Heart Auscultation.

stethovest a simultaneous multichannel wearable system for cardiac acoustic mapping
Biomedical Circuits and Systems Conference, 2018Co-Authors: Christos Sapsanis, Nathaniel Welsh, Michael Pozin, Guillaume Garreau, Gaspar Tognetti, Hani Bakhshaee, Philippe O Pouliquen, Rajat Mitral, William R Thompson, Andreas G AndreouAbstract:Cardiac acoustic mapping remains a highly unexplored area, likely due in part to a decline in research into Heart Auscultation over the past several decades. However, because the stethoscope remains an integral part of clinical care, novel approaches to improve the accuracy and scope of Auscultation are now being explored. The current work introduces an innovative design for Heart acoustic mapping based on a microphone array embedded in a wearable vest. The system incorporates a customized design of a front-end readout channel with discrete components paired with analog to digital converter DAQ modules. The main scope is to provide simultaneous recordings of Heart sounds to generate spatiotemporal images. This noninvasive and time efficient technique will assist in the exploration of normal and pathological Heart activity propagation patterns, providing new knowledge to the current understanding of the cardiac acousteome.
