Smart Speaker Monitors Heart Rhythms
Researchers at the University of Washington have developed an AI-powered sound system that can detect irregular heartbeats. The system sends inaudible sounds into its close environment and then analyzes the reflected waves to identify individual hear...

Correlative Adventures with COVID
By ANISH KOKA “The patient in room 1 should be a quick one, its an addon, they just need a prescription for ivermectin” I’m a bit puzzled by this sentence from my assistant doing his best to help me through a very busy day in the clinic that I’m already behind in. I walk into the room, a script pad stuffed into my hand as I enter the room, to meet a very nice couple.  The wife sits patiently with hands crossed on the exam table.  “So, you’re here for Ivermectin?”, I ask. Why yes, a trip to Texas is planned.. COVID is in the air, the internet, and some important people who have ‘inside ...

Low gradient severe mitral stenosis
Low gradient severe mitral stenosis has been defined as mean transmitral gradient <10 mm Hg in patients with mitral valve area ≤1.5 cm2 [1]. A low flow subgroup has been defined with left ventricular stroke volume index ≤35 mL/m2. In a study of 101 patients with severe rheumatic mitral stenosis who underwent balloon valvuloplasty, low gradient was present in 55 patients and low flow low gradient in 11 patients [1]. Low flow low gradient mitral stenosis patients were older, had higher rates of atrial fibrillation, arterial afterload, subvalvular thickening and decreased left ventricular compliance compare...

Discordant grading of severity of aortic stenosis
Discordance between various measures of severity of aortic stenosis (AS) is considered as discordant grading of severity of aortic stenosis or simply discordant AS. Severe aortic stenosis has aortic Vmax ≥4.0 m/s, mean gradient ≥40 mm Hg and effective orifice area (EOA) ≤1.0 sq. cm. Peak aortic velocity and mean gradient are flow dependent measurements, while effective orifice area and Doppler velocity index are relatively flow independent. About 20-30% of patients may have discordant measures of severity of aortic stenosis on echocardiography [1]. Discordance is mostly between effective orifice area and Vmax/Doppl...

Cardiologists ’ Dream Device? – The Withings BPM Core and the Viatom Armfit+ Joint Review
1 in 4 men and 1 in 5 women have hypertension worldwide, the WHO estimates. As for the most common arrhythmia, atrial fibrillation (AFib), it affects some 33.5 million individuals globally; with its prevalence expected to double by 2030. These cardiovascular conditions need regular monitoring so as to prevent severe complications. For instance, hypertension can lead to heart and kidney failure, while AFib can lead to stroke. For long, monitoring these conditions relied on measurements taken from bulky devices available only in medical facilities; a sphygmomanometer (or blood pressure monitor) for hypertension and an E...

A 50 year old man with sudden altered mental status and inferior STE. Would you give lytics? Yes, but not because of the ECG!
DiscussionFlutter waves are well known to mimic ST deviations, as well as to hide true ischemic ST deviations from the interpreter. In many cases of flutter waves mimicking ST deviations, the expert electrocardiographer can see the morphology of the flutter waves as the cause of apparent STE or STD. Likewise, in some cases of ischemia concealed by flutter waves, the ischemia can be seen despite the flutter waves, whereas in other cases the dysrhythmia must be terminated before the ischemia can be clearly distinguished. Even when flutter waves conceal true ST segment deviations, the cause and effect relationship may be...

Do pro-inflammatory diets harm our health? And can anti-inflammatory diets help?
This study also showed that pro-inflammatory diets were associated with a poor cholesterol profile. This finding was also seen in other another study, also published in JACC, which found that pro-inflammatory foods had a harmful effect on cholesterol levels while some anti-inflammatory foods had favorable effects. What foods are pro-inflammatory and anti-inflammatory? Foods with a higher pro-inflammatory potential are red meat, processed meat, and organ meat; refined carbohydrates such as white bread, white rice, and many desserts; and sweetened beverages including colas and sports drinks. Foods that have a higher anti-inf...

A woman with near-syncope, bradycardia, and hypotension
 Written by Pendell MeyersA 59-year-old woman with diabetes, hypertension, prior stroke, and peripheral vascular disease presented with multiple near-syncopal events over the past 2 days, as well as ongoing back pain. EMS found her bradycardic in the 40s and administered atropine with no response. She was mentating and had a reasonable blood pressure (around 90s systolic), so they decided not to pace prehospital. On arrival the patients blood pressure was 79/50 mm Hg. She was still awake and alert. Here is her first ECG (no baseline available):What do you think?Findings: - junctional bradycardia (no P waves,...

A 45 year old smoker presents with palpitations, is discharged, and is found dead 2 days later
A 45 year old smoker presented with palpitations.  He had no other medical problems.  There was no syncope.  He was on no medications.Unfortunately, no other information is available, but that is enough to provide an learning point.Here is the EKG:Do you see anything worrisome?There are PVCs, and these might be the cause of the palpitations (whether they are indeed the source of the palpitations could easily be ascertained by asking the patient if the palpitations are still present during the ECG).  However, there are wide QS-waves (0.8 ms) in III and aVF, and they have afragmented QRS (extra spike...

Follow-up on my Eight COVID Assertions
Yesterday’s post generated some good comments. Two emergency medicine specialists felt that I was both wrong and insulting in saying that hospitals were not overwhelmed. As a doc in NYC, I would suggest that your assertion 3 was indeed quite wrong and will be wrong in many more places before we are done— Josh Socolow (@Docjoshsoc) December 13, 2020 Jfc you weren't in Connecticut in April, and you aren't here now.We weren't (and aren't) fatally overwhelmed because of massive & costly efforts by our system. Anything less would have been catastrophic.Your blithe dismissal is kind ...
