EDs in Different Parts of the World but the Same Stories
BY TIM DEPP, MDI spent two weeks in India and another two weeks at the Centers for Disease Control and Prevention in Minnesota during my global health elective month. It was a great time to reflect on sustainability in developing world medicine and on my medical education and career goals.Emergency medicine in India is still in its infancy. Some might say it's only just been conceived, still waiting to be born. India is growing incredibly in numerous sectors, and several universities, including George Washington University (GWU), have partnered with established hospitals there to grow the specialty. After completi...

Point-of-care handheld echocardiography
(Hand held echocardiograph – Representative image)
Initially echocardiographs were large machines with poor resolution. Later advances in electronics miniaturized the machines while improving the resolutions. Multiple modes of imaging starting from the initial single dimensional M-Mode and later, 2-D (two dimensional), 3-D (three dimensional), 4-D (live three dimensional) imaging as well as additional techiques like Doppler interrogation, colour flow mapping, tissue Doppler, strain imaging and speckle tracking made echocardiography a versatile diagnostic tool in cardiology. Invasive forms of echocardiography like i...

The Future of Emergency Medicine: Innovations Making Patients The Point-of-Care
Every minute spent without treatment could reduce the chance of survival in case of medical emergency and trauma patients. Digital health innovations making patients the point-of-care could become a great help for first responders and emergency units in the battle against time. Here, we collected what trends and technologies will have an impact on the future of emergency medicine.
Six minutes before brain damage
Car crashes, home injuries, fires, natural disasters. The difference between life and death often depends on the speed and efficiency of emergency care services. The work of doctors, paramedics, and nurses being in...

What is the meaning of hypokinesia, dyskinesia and akinesia?
These terms are used in connection with the heart muscle. Akinesia means lack of movement or contraction of a region of the heart muscle. Dyskinesia means an abnormal movement – instead of contracting in systole, that segment of myocardium bulges out in systole. Hypokinesia means reduced movement or contraction of a segment of the heart muscle. Another term which is sometimes used is hyperkinesia, meaning increased contraction of heart muscle. Hyperkinesia can occur as a compensatory mechanism by which normal heart muscle does a little bit of extra work instead of the heart muscle which is defective with akinesia, hy...

Myocardial contrast echocardiography
Myocardial contrast echocardiography has been used in the assessment of myocardial viability. Downside of myocardial contrast echocardiography is the cost of ultrasound contrast agent (UCA). Intravenous administration of UCA improves the visualisation of myocardial segments and enables the assessment of perfusion. Myocardial segments with normal perfusion and those with patchy perfusion are considered to be viable. Those segments which have no perfusion are taken as non viable myocardial segments. UCA consists of ultrasonic microbubbles. A recent study compared myocardial contrast echocardiography with gated single photon...

Anterior ST Elevation with Elevated Troponin, but with low T/ST ratio, 2 Cases
Case 1This case was sent by Michael Masias (EMCurious, Twitter handle: @EMedCurious), an ultrasound fellow in the Department of Emergency Medicine at UC San Diego.He sent this ECG with the following inquiry: "What do you think about this? 21 year old with chest pain. I am getting a result of " STEMI " by using the 3-variable formula, and " no STEMI " with the 4-variable. "Computerized QTc = 418Here was my immediate answer:" Tough one! There is a very low T/ST ratio. That is to say, the J-point is very elevated in V3 and V4 but without a tall T-wave. That is unusual for both early repol and LAD occlusion, and sug...
