Recently, a team led by Prof. Chen Yan and researcher Sun Qibin from the University of Science and Technology of China (USTC) achieved contactless electrocardiogram (ECG) monitoring through a millimeter-wave radar system. Their work was published in IEEE Transactions on Mobile Computing and reported by IEEE Spectrum.

This 39 year old patient presents with syncope. What do you think? There appears to be RBBB with excessively discordant ST depression (2-2.5 mm) in V2 and V3, suggestive of RBBB with posterior OMI Whenever you see abnormal ST-T (ST elevation, ST depression, hyperacute T-waves), you MUST look at the entire ECG (rhythm, rate, P-waves, intervals, and QRS) to see if there is some abnormality among these which can explain the ST-T.

Every year, the leading minds in imaging gather for the annual Radiological Society of North America meeting in Chicago. It was the event’s second year in person since the start of the COVID-19 pandemic, and attendee numbers are quickly ticking back up now that more and more people have grown comfortable with travel. Healthcare leaders from around the world descended upon McCormick Place to share new research and knowledge and learn about the latest innovations taking the imaging world by storm.

The deacetylase sirtuin 1 (Sirt1), activated by calorie restriction and fasting, exerts several complementary effects on cellular function that are favourable to healthspan; it is often thought of as an ‘anti-aging’ enzyme. Practical measures which might boost Sirt1 activity are therefore of considerable interest. A number of nutraceuticals have potential in this regard.

When you are enjoying an athletic activity, you will notice your heart beats faster than when you are just resting and reading a book. When you exercise, your body may need three to four times your average cardiac output. This happens because your muscles need more oxygen when you exert energy. So what causes pulse deficit, and what is it? Pulse deficit is when one finds a difference in count between heartbeat and peripheral pulse.

Introduction An electrocardiogram machine is used to monitor cardiac rhythms by placing different sensors of electrodes on the body that measure the heart's electrical impulses. ECG machine detects irregular cardiac rhythms and any sign of blocked arteries in the heart. Many ECG machines are available in the market, each with different features and price ranges.

Sent by Drew Williams, written by Pendell Meyers A man in his 50s with history of hypertension was standing at the bus stop when he developed sudden onset severe pressure-like chest pain radiating to his neck and right arm, associated with dyspnea, diaphoresis, and presyncope. EMS arrived and administered aspirin and nitroglycerin. He reported several weeks of intermittent chest pain similar to the active pain, worsening over the past 2-3 days, some of them as long as an hour, but all spontaneou

Now is the opportune time to reflect on your year and start visualizing goals and resoluti ons for the new year. As we quickly approach the start of 2023, it’s a great time to reevaluate and refocus our minds on taking good care of ourselves, particularly our heart health. According to the American Heart Association, heart disease is the leading cause of death in men and women in the United States claiming over 650,000 individuals yearly.

10th December 2022 [The Federal Aviation Authority (FAA), the Food and Drugs Administration, compare and contrast]. A while back I began to write a blog called. ‘ We need a couple of plane crashes. ’ Which may sound a little harsh. But the point I was hoping to make is that plane crashes make front page news around the world. They are highly visible, and terribly frightening.

Written by Pendell Meyers I was reading ECGs in a database (without any clinical information) when I came to this one: What do you think? Seeing only this ECG with no context, I thought this ECG was within normal limits. The upright and large T wave in V1 is unusual, but if it were hyperacute, I did not see reciprocal findings in V6 which would be concerning for LAD OMI pattern (we call that "precordial swirl").

Background There is a paucity of data on cardiovascular magnetic resonance feature tracking (CMR-FT) in patients with dilated cardiomyopathy (DCM). We aimed at describing global and segmental myocardial strain patterns and a potential association with the presence of focal myocardial scarring in DCM patients by CMR-FT. Methods Thirty-nine patients with DCM and reduced left ventricular (LV) ejection fraction (mean 21±8%) underwent CMR including standard cine steady-state free precession (SSF

A really interesting paper was published late November by pathologists at Heidelberg University that reviews the potential link between vaccine myocarditis and sudden death. It is interesting particularly because the ensconced narrative in academic circles and the medically related twitterati that seem to have an outsized influence on COVID related policy has been that vaccine myocarditis is “mild” Leo Lam, Ph.D.💉⚕️🌎🇺🇸🇬🇧

Objective The reduction in circulating low-density lipoprotein cholesterol (LDL-c) is the primary aim of lipid-lowering therapies as a method of atherosclerotic cardiovascular disease risk reduction. Inclisiran is a new and potent lipid-lowering drug that is shown to be effective in reducing LDL-c in randomised controlled trials, however, real-world data of its use are not yet known.

Aims Strain artefacts are known to hamper the correct interpretation of segmental strain and strain-rate (S/SR). Defining the normal ranges of myocardial segmental deformation is important in clinical studies and routine echocardiographic practice. In order to define artefact-free normal ranges for segmental longitudinal S/SR parameters, we investigated the extent to which different types of artefacts and their segmental localisation in the three different myocardial layers created a bias in the

Aims The aim of this study was to investigate a real-world heart failure (HF) cohort regarding (1) prevalence of known diabetes mellitus (DM), undiagnosed DM and pre-diabetes, (2) if hf treatment differs depending on glycaemic status and (3) if treatment of DM differs depending on HF phenotype. Methods All patients who had received a diagnosis of HF at Umeå University Hospital between 2010 and 2019 were identified and data were extracted from patient files according to a prespecified protoc

Background The postdischarge prognostic implication of periprocedural myocardial injury in patients undergoing percutaneous coronary intervention (PCI) of a chronic total occlusion (CTO) remains scarcely studied. Aims The aim of this study is to assess the prognostic value of periprocedural myocardial injury, defined by increased high-sensitive troponin T (hs-TnT) levels according to updated guidelines, after CTO PCI.

Background Patients undergoing transcatheter aortic valve implantation (TAVI) often have multiple comorbidities, such as anaemia and chronic inflammatory disorders. We sought to investigate the association between preoperative and postoperative haematological parameters and clinical outcomes in TAVI patients at mid-term follow-up. Methods In the present study, consecutive patients (N=908) who underwent TAVI at the Cleveland Clinic between 2017 and 2019 with available complete blood counts were s

I was texted this ECG by one of my partners, with the following history: A 60-something male with diabetes and HTN presented with syncope. Per EMS report, the patient had a syncopal episode at work. On medics arrival, patient noted to be pale and diaphoretic, SBPs 60-80s, complaining of nausea and had one episode of emesis en route, possible hematemesis.
