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.

31st December 2022 Before laying into the drug regulators, and their inexorable move towards the dark side, I thought I should try to explain a bit more about who decides what drugs should be used, and for what conditions. Yes, I know, for most people this appears simple. The Federal Drugs Administration (FDA), in the US, or the European Medicines Agency (EMA), for the European Union, approve drugs for use in human beings, and that’s pretty much that.

Electrocardiography (ECG) is a diagnostic tool that measures the heart's electrical activity. It is commonly used to diagnose heart attacks, arrhythmias, and other heart conditions. An ECG machine consists of electrodes placed on the patient's chest, arms, and legs, which record the heart's electrical activity and display it on a screen. There are two main types of ECG machines: digital and analog.

A normal functioning aortic valve has three leaflets, usually referred to as cusps, and is positioned at the end of the left ventricle. This valve is the main pump that delivers oxygenated blood to the entire body. An aortic valve replacement is required if someone suffers from Aortic Valve Stenosis or Aortic Valve Insufficiency. These two issues can cause a significant number of problems and can be life-threatening.

I was working in triage very late when a 30 yo previously completely healthy woman walked in with 30 minutes of central chest pressure. This ECG was recorded: The computer called it "Normal" except for "Possible right ventricular conduction delay" What do you think? I immediately recognized an inferior-posterior-lateral OMI. There are hyperacute T-waves in II, III, and aVF.

ECG machine use Most of us have been recommended an ECG test at least once. Any symptoms related to abnormal heart activity require an ECG test to rule out the cause. ECG and EKG refer to the same thing. However, an echocardiogram is a different test, also conducted for heart activity. An electrocardiogram is a machine used to record the heart's electrical activity.

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.

Dr. Jesse McLaren discusses some key aspects of cocaine chest pain ECG interpretation in this month's blog including: Patients with cocaine-associated chest pain require benzodiazepines +/- nitroglycerine for symptom relief, aspirin and ECG to look for signs of occlusion and reperfusion. In patients with chest pain + ST elevation, consider false positive STEMI including early repolarization, LVH and Brugada-pattern.

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.

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.

One of the great joys of my role is getting to see the impact a new imaging system can have on a healthcare provider and, ultimately, their patients. In fact, the most rewarding experiences are when we get to see the profound personal effect providers have on their patients. Sometimes that means watching the installation of the facility’s first MRI that will enable them to provide access to their population on a daily basis rather than rely on a once-per-week mobile solution.

The term MINOCA stands for Myocardial infarction with non-obstructive coronary arteries. I’ll try and explain this a bit better by using a case study.

She had a blood test to measure Troponin.

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").

However when we really examine heart disease closely there are in general mainly 3 things that can go wrong with the heart and cause harm and if we know this then we are able to firstly understand the different conditions better but also get our head around why certain tests are done and what they tell us.
