The Slimmest ECG Ever Created: A Review
A couple of weeks ago, AliveCor, a leading innovator in the FDA-cleared personal electrocardiogram (ECG) technology space, announced the launch of the KardiaMobile Card.
The KardiaMobile Card is the slimmest and smallest self-contained, commercially available ECG that has been created to date. It is the size of a standard credit card, and is able to deliver a medical-grade, single-lead ECG in 30 seconds.
It’s very empowering that such a small device has been cleared for use by the FDA, as this puts the power of real-time ECG analysis directly into patients’ wallets or purses and provides the user with a...

Good news: Nothing much has changed since 2008
Recognizing the clinical importance of AF and the need to rule out a systemic cause is the key, Further, a genuine bedside debate about the pros and cons of simple vs aggressive treatment discussion is welcome.
The nomenclature issue of valvular vs non-valvular has finally seemed to have settled. The latter is banished for good reason. (Funny to note Aortic valve was conside...

Toothache, incidental Wide Complex Tachycardia
Discussion by our ElectrophysiologistSmith: “I thought that the wide complex tachy (WCT) could be AVRT or VT” EP: " Antidromic AVRT morphology would essentially be the same as “VT” originating from ventricular the insertion site of the accessory pathway. Therefore, traditional criteria for SVT with aberrancy do not apply to antidromic AVRT (except, that negative concordance can never be AVRT!) " Smith: “But then when the patient converted and had PVCs of exactly the same morphology as the WCT, that it must be VT and not AVRT ” EP: " In cases of intermittent pre-excitation, you cou...

POEMS Electro-Optical Cardiac Stimulator to Study Arrhythmias
At the University of Bern in Switzerland, researchers have developed the Panoramic Opto-Electrical Measurement and Stimulation (POEMS) system, which allows them to conduct advanced optogenetic experiments with mouse hearts. The device, which contains a volume into which a mouse heart can be placed, lets the Swiss team stimulate various cell types using light, and then measure the resulting electrical response. Previously, scientists had no way to track electrical activity and provide accurate optical stimulation at the same time. The new technology may help to determine the contribution of various cell types to cardiac fun...

Remote Monitoring for Cardiac Patients: Interview with Dr. Waqaas Al-Siddiq, CEO of Biotricity
Biotricity, a medtech company based in California, developed the Bioflux system, a mobile cardiac telemetry device. The system is a three channel ECG monitor, and it enables continuous data collection and data transmission to a call center in the case of anomaly detection. If the detected issue is considered to be serious, a clinician can contact the patient to check up and make a call about whether to intervene.
Remote cardiac monitoring has made it easier to spot intermittent issues such as arrhythmias, and it allows clinicians to build up a long term picture of someone’s cardiac health as they go about their daily ...

Cell Signaling via Exosomes in the Development of Vascular Calcification
https://www.fightaging.org/archives/2021/05/cell-signaling-via-exosomes-in-the-development-of-vascular-calcification/
Vascular calcification is a feature of aging, a process in which cells in the blood vessel wall take on inappropriate identities and activities that are more appropriate to bone tissue. Evidence of recent years implicates chronic inflammation and the presence of senescent cells in this process. Senescent cells cau...

Mitochondrial Dysfunction as a Cause of Atrial Fibrillation
For any given age-related condition, you will find papers in the literature that focus on one mechanism of aging and its contribution to that condition. Usually these are reviews covering the details of the mechanism and how it causes pathology, or the epidemiology of the mechanism in the field, as absent an effective means of intervention it is very challenging to establish just how large a contribution that mechanism actually has.
While looking through the work here on age-related mitochondrial dysfunction and atrial fibrillation, it is worth also taking a look at past work on senescent cell burden as a cause of a...

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 heartbeats from someone sitting close to it. The technology may be useful in detecting heart rhythm disorders, such as cardiac arrhythmias.
“Heart rhythm disorders are actually more common than some other well-known heart conditions. Cardiac arrhythmias can cause major morbidities such as strokes, but can be highly unpredictable in occurrence, and thus difficult to diagnos...

Phenocopies of hypertrophic cardiomyopathy
Hypertrophic cardiomyopathy (HCM) is characterized by hypertrophy of the left ventricle, not related to load. It is a genetically transmitted condition. There are several mimickers of hypertrophic cardiomyopathy which can be called phenocopies of hypertrophic cardiomyopathy. Conventional form of HCM has been called sarcomeric HCM as it is due to mutations in genes encoding sarcomeric proteins [1].
Here is a small list of phenocopies of hypertrophic cardiomyopathy which is not truly exhaustive:
Fabry disease
Danon disease
PRKAG2 Cardiomyopathy
Pompe disease
Cardiac amyloidosis
Athlete’s heart
Hypertensive heart disease

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...

BIOMONITOR IIIm Injectable Cardiac Monitor Can Now Look for Signs of Fever
BIOTRONIK won FDA clearance for the Vital Data Sensor, a body temperature component within the BIOMONITOR IIIm injectable cardiac monitor (ICM). The ICM is designed to help cardiologists detect and diagnose cardiac arrhythmias remotely, but thanks to the Vital Data Sensor the implant now has an additional role in monitoring for signs of fever. This is particularly important right now as the COVID-19 pandemic lingers on, but will remain a useful patient monitoring tool even when the current virus recedes.
“The patient is at high risk for infection during this global pandemic due to underlying conditions,” sa...

A Fall and a Rhythm to Recognize
CONCLUSION: The above bullets point out too many findings to be by chance. Therefore, these consistent relationships that are highly unlikely to be by chance tell us — there must be some type of conduction going on in this irregular, long-lead rhythm strip.PEARL #2: It is sometimes very helpful to “step back” a little bit from the tracing — to gain an overall perspective of the pattern of a complex rhythm. PROVE THIS to yourself. Go BACK to my unlabeled Figure-1— and take another look at the long-lead rhythm s...

Arrhythmia basics: How often we need to know the mechanism of arrhythmia ?
How many times you have treated cardiac arrhythmia in both emergency & non-emergency situations?
Infinite times.
How many times did you really bother to know the mechanism of a given arrhythmia before ordering medication or shocking?
Hmm,.. let me think. (Except for AVNRT/ AVRT, and few VTs, very rarely I have worried about the mechanism !)
Why is it so? because treatment takes priority and we are able to tame the arrhythmia even without knowing the real mechanism.
The following slide is a gross summary of the cardiac arrhythmia mechanism
Understanding cardiac arrhy...

SCD-HeFT 2005
The Sudden Cardiac Death in Heart Failure Trial (SCD-HeFT) trial was published in NEJM in 2005 [1]. SCD-HeFT randomized 2521 patients into three groups. They were in New York Association (NYHA) class II or III congestive heart failure (CHF) and had left ventricular ejection fraction (LVEF) ≤35%. It was a comparison between amiodarone or an implantable cardioverter-defibrillator (ICD) for congestive heart failure, with placebo control. The patients were divided into three groups:
Conventional therapy for CHF plus placebo (847 patients)
Conventional therapy plus amiodarone (845 patients)
Conventional therapy plus a con...

At-Home Clinical ECG: Now and After The Pandemic – Interview with Dr. Ruey-Kang Chang, CEO, QT Medical
Many fields of medicine are undergoing a transformation due to the COVID-19 pandemic, as patients are kept away from clinics as much as possible. Patients are now regularly visited by their doctors over video calls, are asked to perform certain procedures on their own, and are prescribed medical devices that would normally be used by clinical staff.
Heart monitoring is the most important component of medical care for millions of people suffering from cardiovascular conditions, particularly those most at risk from COVID-19 complications. But receiving a clinical grade electrocardiogram (ECG) normally involves office...
