Six-Lead, Consumer-Facing ECG Device Close to Release to Market
I have previously blogged aboutAliveCor's three-lead ECG device in particular and cardiology in general as examples of cardiology being a"collision point" between consumer IT and the healthcare system (see:Three New Studies Confirm Clinical Utility of AliveCor ’s KardiaMobile Device and AI Algorithms;Cardiology as a"Collision Point" between Consumer IT and the Healthcare System). The company is now testing a a six-lead ECG instrument (see:AliveCor previews next product: A 6-lead smartphone ECG). Here is an excerpt from this article:AliveCor, which has offered an smartphone-connected ECG sinc...

MitraClip: Valve repair device offers new treatment option for some with severe mitral regurgitation
Mitral valve regurgitation (MR), a condition in which the mitral valve does not close properly, allowing blood to leak back into the heart’s upper chamber, is the most common disease of the heart valves. It can cause symptoms such as cough, fatigue, and trouble breathing. The risk of MR increases with age.
Until recently, there were only two methods of treatment for MR: medication and open-heart surgery. During this surgery, the surgeon accesses the heart by opening up the breastbone. He or she either repairs or replaces the mitral valve while a heart-lung machine takes over the job of the heart and lungs while the heart...

An elderly woman transferred to you for chest pain, shortness of breath, and positive troponin - does she need the cath lab now?
Written by Alex Bracey, with edits by Smith and MeyersA female in her 70s presented to the ED at sign out while working in our acute zone (medium acuity). I picked up the chart and the triage note indicated that the patient was transferred from another hospital, with " EKG changes " and elevated troponin, for cardiology evaluation of NSTEMI. Symptoms were ongoing.Interest now piqued, I looked at the EKG and saw the following:What do you think? Baseline for comparison below.This is nearly pathognomonic! Of what?Baseline on file from outside hospital:This is her first ECG at our hospital:Meyers ECG interpretation: ...

What happens when a patient with LAD OMI does not go immediately to the cath lab?
This patient was extremely elderly, and although the diagnosis was recognized, she did not go to the cath lab for reasons related to age and patient/family choice.Nevertheless, there is a lot to learn from the ECGs.I was shown this ECG without any information:QTc = 431 msWhat was my response?I immediately said:" Acute LAD occlusion. OcclusionMI (OMI) " (And sinus rhythm with a PVC.) (Not quite a STEMI, but same effect.)Why did I diagnose LAD occlusion?There isST elevation in V2-V4 that does not quite meet " STEMI criteria. " Is it normal ST elevation? No! How do I know? First, there is re...

Endothelium derived vasodilator – Cardiology MCQ – Answer
Endothelium derived vasodilator – Cardiology MCQ – Answer
Which of the following is not an endothelium derived vasodilator?
Correct answer: 4. Endothelin
Endothelin is powerful vasoconstrictor derived from the endothelium.
In humans, endothelium derived vasodilator function is assessed by measuring flow mediated vasodilation. This is done by measuring the brachial artery diameter and flow using a vascular ultrasound probe. After taking baseline measurement of vessel diameter and Doppler flow, blood pressure cuff is inflated. Increase in diameter due to flow mediated vasodilation can be assessed by repeat ...
