Wide Complex Tachycardia -- VT, SVT, or A Fib with RVR? If SVT, is it AVNRT or AVRT?
A 69 y.o. male with pertinent past medical history including Atrial fibrillation, atrial flutter, cardiomyopathy, Pulmonary Embolism, and hypertension presented to the Emergency Department via ambulance for respiratory distress and tachycardia. Per EMS report, patient believes he has been in atrial fibrillation for 5 days, since coming down with flu-like illness with rhinorrhea, productive cough, SOB. Patient is on rivaroxaben, carvedilol, and dofetilide (to suppress atrial fib -- rhythm control). He states that he maybe missed a dose or two during recent illness. On EMS arrival, patient ' s oxygen sat...

Interesting Epidemiological Results for Time Restricted Feeding
In this study, researchers investigated the potential long-term health impact of following an 8-hour time-restricted eating plan. They reviewed information about dietary patterns for participants in the annual 2003-2018 National Health and Nutrition Examination Surveys (NHANES) in comparison to data about people who died in the U.S., from 2003 through December 2019, from the Centers for Disease Control and Prevention's National Death Index database.
The analysis found: (a) people who followed a pattern of eating all of their food across less than 8 hours per day had a 91% higher risk of death due to cardiovascular d...

Important Complications of Eisenmenger Syndrome
Transcript of the video: Eisenmenger syndrome is an important complication of large left to right shunts which develop later due to development of pulmonary vascular obstructive disease and severe pulmonary hypertension. The first report of Eisenmenger was by Victor Eisenmenger in 1897 and that was in a thirty year old person who later succumbed to massive hemoptysis. This highlights one of the most important complications of Eisenmenger syndrome, that is airway hemorrhage. Airway hemorrhage can occur in those who ascend to high altitude and during air travel. But it commonly occurs at low level itself. It is one of the mo...

10 Things You Can Definitely Expect From The Future Of Healthcare AI
The steady cadence of a heart monitor. The anxious wait for test results. These define a patient’s experience, but for healthcare professionals, they are also points of friction. Missed information, redundant diagnostics, or the struggle to make time for true connection… these burdens hinder the most skilled and compassionate providers.
Artificial intelligence promises material changes on both sides of the stethoscope. By streamlining processes, pinpointing insights, and augmenting decision-making, AI won’t just change how care is delivered – it will reshape the very experience of both giving a...

A man in his 50s with shortness of breath
Sent by Tom Fiero, written by Pendell Meyers A man in his 50s presented with acute shortness of breath. Unfortunately we do not have access to the patients presenting vital signs.Here is his ECG:Original image, suboptimal qualityQuality improved with PM Cardio digitizationThe ECG is highly suggestive of acute right heart strain, with sinus tachycardia, S1Q3T3, and T wave inversions in anterior and inferior with morphology consistent with acute right heart strain. There is also STE in lead III with reciprocal depression in aVL and I, as well as some subendocardial ischemia pattern with STD in V5-V6 and STE in aVR. Thus...

Important Normal Values for ECG
Transcript of the video: Normal values for ECG will depend on the age, body size, gender, as well as the population being assessed. So there is a wide variation. Still, in a normal adult population, some normal values are useful, while assessing an ECG.
These are the normal waves which you expect on the ECG and normal heart rate in an adult is 60 to 100 per minute. P wave, the atrial activation, PR segment, QRS complex – ventricular activation, ST segment, and T wave, ventricular repolarization. Atrial repolarization wave is usually not seen in a standard surface ECG. It will somewhere in the ST segment (error: PR se...

Predicting the Order of Arrival of the First Rejuvenation Therapies
It has been going on eight years since I last speculated on the order of arrival of the first rejuvenation therapies. Tempus fugit, and time for an updated version! Eight years is a long enough span of time for the first of those rejuvenation therapies to now exist, albeit in a prototypical form, arguably proven in principle but not concretely. The world progresses but my biases remain much the same: the first rejuvenation therapies to work well enough to merit the name will be based on the SENS vision, that aging is at root caused by a few classes of accumulated cell and tissue damage, and biotechnologies that either repa...

Pediatric Exercise Testing
Discussion on pediatric exercise testing.
Pediatric exercise testing may be used for evaluation of various disorders of cardiac rhythm rather than for inducible ischemia as in adults.
In a child with suspected sinus node dysfunction, chronotropic incompetence from sinus node dysfunction can be assessed by exercise testing.
Evaluation of escape rates and ventricular ectopy with exercise in complete heart block is an important aspect in the evaluation of congenital complete heart block.
ECG showing congenital complete heart block with ventricular rate of 47/min and atrial rate of 63/min.
In stage I of Bruce protocol, the atr...

Estrogen-Related Receptor Agonists as Exercise Mimetic Drugs
Just as the research community is interested in finding pharmaceutical ways to provoke some the beneficial reactions to calorie restriction, there is also considerable effort devoted to the search for drug candidates that can mimic some of the benefits of exercise. If the history of calorie restriction mimetic drug development is any guide, this will be a slow process, and the resulting compounds will produce lesser benefits than actual exercise, as they will only touch on a small subset of the processes involved. Still, there is no shortage of programs in this space, and here is one example.
Exercise benefits bot...

Medical school gap year: Why working as a medical assistant is perfect
The words “gap year” are enough to panic any high-achieving premedical student with their heart set on matriculating straight into medical school. Many students feel like a gap year will set them back in their journey to become a doctor, adding more years to the ever-long path to an MD behind their name. What these

Sunday Sermonette: Weird Theology
Now we say goodbye to Asaph, and start what was evidently originally a new hymnal. " Gittith " is probably a musical instrument, but it could be a tune. The meaning is unknown. Anway, whenever these were composed, they aren ' t monotheistic. In psalm 84, Yahweh is the " God of gods " in verse 7, and otherwise the " Lord of hosts, " referring to an assemblage of god over which Yahweh is supreme. Psalm 85 is another of those that refers to some unspecified time in which the nation is afflicted and God seems to have withdrawn his favor. It does not seem to refer to the Babylonian exile, however, because the people seem s...

This study also reports the expansion of satellite cells in human muscle with CR. This finding is critical to suggest translational relevance to the rodent data observed for more than a decade. Moreover, the increased expression of the plasminogen receptor Plg-RKT observed on human satellite cells during CR provided additional support for the theory that our rodent model is relevant to human biology.

Windkessel Effect In Aorta With Experimental Evidence!
Windkessel effect is applicable to large elastic arteries like aorta, which are situated close to the heart. They have more of elastic tissue than muscular tissue. The term Windkessel comes from German language and means air chamber.
Here is an illustration of the Windkessel, used in 18th century, by fire fighters. The additional pressure built up in the air chamber will ensure continuous delivery of water for fire fighting. A similar thing occurs in elastic arteries like aorta. During systole, more blood enters the aorta, than what leaves the aorta, because aorta expands. This additional blood received during systole, is ...

Head Up Tilt Test (HUTT)
Transcript of the video: Head up tilt test, is usually done for the evaluation of recurrent syncope. Sometimes, head up tilt test, also known in short as HUTT, is also done for the evaluation of postural orthostatic tachycardia syndrome, POTS, a condition in which there is tachycardia on standing up, without a fall in blood pressure. In usual syncope, there could be a fall in blood pressure, bradycardia, and there are various types, which will be described.
There are various protocols for head up tilt test, which are followed in different institutions. Basically you need a tilt-table, in which the person is lying down fir...
