Accelerating Personalized Health With Healthcare Digital Twins
The following is a guest article by Steve Lazer, Global Healthcare & Life Sciences CTO at Dell Technologies.
One rapidly advancing trend in healthcare and life sciences is the shift from inefficient, expensive physical models to digital models tested in the virtual world. This is especially critical when time to value and cost are of the essence, as in the case of a global pandemic. One way to address this challenge, is to create a digital replica of a physical system or environment, accumulate data with sensors and collectors to monitor performance, and identify anomalies and trends to predict problems before they oc...

A 50-something with chest pain. what to do? And get the PM Cardio app for your own use here!
This was sent to me by a friend.It is from a 50-something with chest pain:What do you think?This was marked as " Not a STEMI " by the physicians. It is not a STEMI, but it isdiagnostic of an LAD OMI (Occlusion MI). There is subtle ST Elevation in V1-V4 and hyperacute T-waves in V2-V6.There is also subtle but diagnostic INFERIOR ST Elevation, with reciprocal ST Depression in aVL.I uploaded this to our new PM Cardio AI Bot app. We call the app the " Queen of Hearts "First, it transforms it to a digital file and standardizes the image. Here is the result:Next, it interprets the digital data:A...

What is strange about this paroxysmal atrial fibrillation in an otherwise healthy patient? And what happened after giving ibutilide?
Conclusions.The efficacy of transthoracic cardioversion for converting atrial fibrillation to sinus rhythm was enhanced by pretreatment with ibutilide. However, use of this drug should be avoided in patients with very low ejection fractions. (N Engl J Med 1999;340:1849-54.) Smith comments from the full text: They included patients who had had a fib for less than 48 hours They excluded patients with a fib for longer than 48 hours unless they proved, by TE echo, to not have an atrial thrombus OR unless they anti-coagulated them for 3 weeks first *Therefore, our patients who have been in afib< 48 hours, or who h...

P wave spotting in AF is not forbidden
Fibrillation is a continuous, chaotic muscular activity. In AF, atrial muscle is expected to lose all coordinated contractions with fibrillatory waves replacing P waves. Have you ever spotted a suspicious P wave in a strip of otherwise explicit AF? If not, this write-up is not for you.
An evolving rare theme in Atrial fibrillation
Have a look at this ECG
Here is an ECG, that was reported as AF, multiple APDs, or Possible AF, Pre AF. I suggested the term AF in transition. While few agreed, many said it is a straightforward SR with APDs, making it appear irregular RR.
But, the fact of ...

Missing links in IHD : What is the relationship between Ischemia & cardiac arrhythmias ?
The term Ischemic heart disease (IHD) was once very popular, but many abandoned it as it became an academic cliche. CAD & CAHD are the other terms that are equally popular and prevalent. Stable IHD was in vogue till recently, which was again replaced by “chronic coronary syndrome’ now. Honestly, I feel the original term IHD to be restored however outdated it may look. it encompasses the entire spectrum of clinical cardiac disorders.
Manifestation of Ischemia heart disease
Angina
Infarction
Cardiac failure
Arrhythmias
Silent ischemia
Sudden cardiac death

As Balwani and Holmes Head To Jail …Will Others in Health Tech Follow?
by MIKE MAGEE
This week’s headlines seemingly closed a chapter on the story of medical research criminality in America. Ramesh “Sunny” Balwani, former president and COO of Theranos was sentenced to 13 years in prison for fraud. That’s 2 years more than his former business and romantic partner, Elizabeth Holmes.
White crime criminal defense attorney for all things science tech, Michael Weinstein, took the opportunity to trumpet out a confident message that crime doesn’t pay in Medicine with these words, “It clearly sends a signal to Silicon Valley that puffery and fraud and misrepresentation will be pr...

Patient in Single Vehicle Crash: What is this ST Elevation, with Peak Troponin of 6500 ng/L?
A 30-something male was involved in a single vehicle crash and had multiple injuries. As a routine part of his critical trauma evaluation, he had an ECG recorded:There is an rSR " in V1 and V2, with downsloping ST segment and inverted T-wave which is very similar to a Brugada Type 1 phenocopy. I was shown this ECG and thought that it could perhaps be Brugada, butI was more suspicious for Right Ventricular (RV) myocardial contusion. The RV is the most anterior part of the chest and is most likely to be contused with anterior chest trauma. Moreover, this degree of ST Elevation is very unusual for B...

Aerobic training
Aerobic exercises are those which stresses the oxygen transport system while resistance exercises stress the musculoskeletal system. Target heart rate for aerobic training is 70 percent of the maximum predicted heart rate. Maximum predicted heart rate is 220-age of the individual.
While doing a treadmill exercise test often we aim at above 90% of the maximum predicted heart rate. But when a treadmill test is done for risk stratification soon after myocardial infarction (pre-discharge; seldom done in this era of early invasive management), only a target heart rate of 70% of maximum predicted heart rate is aimed.
During aer...

Apple Heart Study – Clinical Trial Review
Apple Heart Study – Clinical Trial Review
The Apple Heart Study was designed as a large-scale, app-based study to identify cardiac arrhythmias using a smartwatch [1]. Pulse rate can be measured using smartwatch and fitness band wearable consumer electronic devices by photoplethysmography. Pulse irregularity from these data can potentially identify atrial fibrillation.
Participants without self reported atrial fibrillation used a smartwatch (Apple iPhone) app to consent to monitoring. If possible atrial fibrillation was detected by the smartwatch algorithm, a telemedicine visit was initiated and an ECG patch was maile...

What Is GHB Anyway?
Let’s face it, there are a whole bunch of street drugs out there that we as EMS caregivers should understand. While we can’t always be expected to identify the exact drug a patient has ingested. We do need to be able to predict a given drugs effect on the body.
We should also be able to take a fair guess at the identity of an ingested drug based on our evaluation of the patient’s physical presentation. GHB is one of those drugs that can be hard to nail down based on the physical signs. But it does leave some clues – if you know what your look for.

GHB is short for ...

What is Ebstein ’s anomaly? Cardiology Basics
What is Ebstein’s anomaly? Cardiology Basics
Ebstein’s anomaly is a congenital anomaly of the tricuspid valve, which may manifest soon after birth or more commonly later in life. In Ebstein’s anomaly, two of the three leaflets of tricuspid valve are displaced further into the right ventricle. Usually anterior leaflet is not displaced while the septal and posterior tricuspid leaflets are displaced. So, a part of the right ventricle becomes part of the right atrium functionally and is called atrialized right ventricle. Undisplaced anterior leaflet is elongated.
The tricuspid valve in Ebstein’s anomaly can have severe...

What are ventricular ectopic beats (VPC)? Cardiology Basics
Ventricular ectopic beats are premature heart beats originating from the ventricles. Normal heart beats originate from the sinus node, situated in the upper part of right atrium. Sinus node is the natural pacemaker of the heart which gives out regular impulses to induce sequential contractions of atria and ventricles.
Ventricular ectopic beats (VEB) are also known by other names like ventricular premature beat (VPB), ventricular premature complex (VPC) and premature ventricular complex (PVC). Ventricular ectopic is the commonest form of cardiac arrhythmia.
In a ventricular ectopic beat, the sequence of activation is diffe...

What is an implantable cardioverter defibrillator (ICD)? Cardiology Basics
Implantable cardioverter defibrillator or ICD is a cardiac implantable electronic device or CIED. The device is implanted subcutaneously under local anaesthesia, usually below the left clavicle. The electrodes from the device are introduced into the right sided cardiac chambers through a subclavian vein puncture. The ICD senses and analyzes heart rhythm continuously. It can detect life threatening ventricular arrhythmias and treat them electrically.
If a ventricular tachycardia is detected, the ICD tries to overdrive it by fast pacing. If it does not suppress the ventricular tachycardia, the ICD delivers a shock through i...

What is commotio cordis? Cardiology Basics
Sometimes a player drops down dead after being accidentally hit by a ball or another player. This situation which can occur in any contact sports is known as commotio cordis. The sudden impact on the chest causes cardiac arrest due to ventricular fibrillation.
The intensity of the blow is not sufficient to cause any damage to the chest wall. No structural damage is noted in the heart as well. If there is a contusion of the heart, it will be called contusio cordis. Contusio cordis is associated with damage to the chest wall as well.
The rapid rise in left ventricular pressure following the impact possibly results in mechan...

Is there Terminal QRS Distortion?
This ECG has ST Elevation in multiple leads. Is it normal STE? Or is it ischemic STE?What do you think?This ECG is interesting because itmimics TQRSD. There are no S-waves in V2 and V3. BUT look at the very prominent J-waves (J point notching)!! It is several mm high!This is a normal ECG.This patient had CO poisoning but did not have myocardial injury or OMI. In fact, there was no chest pain either.This is a great demonstration that a normal ECG, if there is no S-wave in V2 and/or V3, the lead without an S-wave MUST have a J-wave in order to be truly normal.Anterior OMI? ...
