Primary endpoint was the incidence of patients with new onset supraventricular arrhythmia (AF, atrial flutter or any supraventricular tachycardia) lasting >30s, post PFO closure.ResultsA total of 59 patients met the inclusion criteria. A total of 88 supraventricular arrhythmia events (96.6% days (IQR 1321). days (IQR 1321).
milla1cf Wed, 06/19/2024 - 20:57 June 19, 2024 — When electrophysiologist Eugenio Cingolani, MD , isn’t seeing patients, he can usually be found in his laboratory, investigating improved treatments for heart rhythm disorders. Eugenio Cingolani, MD. Photo by Cedars-Sinai. Q: How quickly might we see a clinical trial for patients?
BackgroundAtrial fibrillation (AF) is the most common arrhythmia worldwide. Data regarding AF screening in conflict countries emergency departments (ED) is lacking.MethodsWe included consecutive patients >40 years old who reported to the ED of a Syrian tertiary centre between July 2024 and September 2024.
She had a single chamber ICD/Pacemaker implanted several years prior due to ventricular tachycardia. Answer : The ECG above shows a regular wide complex tachycardia. Said differently, the ECG shows a rather slow ventricular tachycardia with a 2:1 VA conduction. Cardiac output (CO) was being maintained by the tachycardia.
For more on Torsades de Pointes vs PMVT See My Comment in the October 18, 2023 post and the September 2, 2024 post in Dr. Smith's ECG Blog ). Even with tachycardia and a paced QRS duration of ~0.16 In this specific case, Left Bundle Branch (LBB) area pacing was pursued to achieve cardiac resynchronization. (J J Am Coll Cardiol.
My New E CG P odcasts ( 5/28/2024 ): These podcasts are part of the Mayo Clinic Cardiovascular CME Podcasts Series ( "Making Waves" ) — hosted by Dr. Anthony Kashou. 25:00 — The advantage of getting a 12-lead in an unknown tachycardia = “12 Leads are Better than One” ( = You have 12 leads to tell if the QRS is wide or narrow! ).
or is he an ACCESS Trial Candidate? == MY Comment , by K EN G RAUER, MD ( 7/5 /2024 ): == Clinical ECG interpretation is a 2-Step process. Confirmation of sinus tachycardia should be easy to verify when the heart rate slows a little bit ( as the patient's condition improves ) — allowing clearer definition between the T and P waves.
A DDENDUM ( 12/13/2024 ) : I've reproduced below from ECG Blog #361 a number of helpful figures and my Audio Pearl on assessment of the regular WCT rhythm. Review of the Idiopathic VTs ( ie, Fascicular VT; RVOT and LVOT VT ) See My Comment at the bottom of the page in the September 7, 2020 post on Dr. Smiths ECG Blog.
Easy LINK — [link] — My New E CG P odcasts ( 5/28/2024 ): These podcasts are part of the Mayo Clinic Cardiovascular CME Podcasts Series ( "Making Waves" ) — hosted by Dr. Anthony Kashou. 22:25 — What if you have a regular SVT ( = narrow-complex tachycardia ) without obvious P waves? ( speed should be optimal for you! ).
The ECG shows sinus tachycardia with RBBB and LAFB, without clear additional superimposed signs of ischemia. Retrieved July 2, 2022, from [link] == MY Comment , by K EN G RAUER, MD ( 2/4 /2024 ): == Today's case by Dr. Meyers provides insight with regard to sequential evolution of serial ECGs during the course of cardiac contusion.
Unlike paroxysmal AF, which describes symptoms that last for seven days or fewer, persistent AF is a sustained arrhythmia that lasts for more than a week 1. Food and Drug Administration approval of the FARAPULSE PFA System in the first quarter of 2024. The company now anticipates U.S. Caution: Investigational Device.
There is a regular wide complex tachycardia. Remember : Adenosine is safe in Regular Wide Complex Tachycardia. Rather, from this one: Very Fast Very Wide Complex Tachycardia Ideally, one would cardiovert. PEARL #1: The most commonly overlooked arrhythmia is AFlutter ( A trial F lutter ).
Because of this, it is uncommon to see sinus tachycardia with a prolonged PR interval. P utting I t A ll T ogether: At this point in my assessment of today's rhythm — I fully acknowledge that I did not know for certain the etiology of this arrhythmia. Figure-3: How to assess for possible 2:1 atrial activity. =
Circulation, Volume 150, Issue Suppl_1 , Page A4136459-A4136459, November 12, 2024. Ventricular arrhythmias (VA), such as ventricular fibrillation and ventricular tachycardia, are the major causes of mortality among patients with CAD.
Circulation, Volume 150, Issue Suppl_1 , Page A4143264-A4143264, November 12, 2024. This can initiate ventricular arrhythmias like polymorphic ventricular tachycardia (PMVT). Background:R-on-T phenomenon occurs when an electrical stimulus is delivered at a critical point during ventricular repolarization.
EMS reports intermittent sinus tachycardia and bradycardia secondary to some type of heart block during transport. It is hard to make out P waves but you can see them best in V2, and notches in the T waves in other leads - this is a sinus tachycardia with a very long PR interval indicating first degree block.
Arrhythmia? Today’s case recalled that scenario for me, in that it features recognition of an arrhythmia that fooled ED staff into thinking the ECG was showing an acute infarction. The ED staff failed to do this — and as a result, they completely overlooked the arrhythmia. Would you give lytics? Yes, but not because of the ECG!
This strip was obtained: Apparent Wide Complex Tachycardia at a rate of 280 What do you think? Troponins 34>33>43, likely secondary to myocardial injury from tachycardia. Sinus tachycardia does not go this fast. A 60-something ow healthy male had syncope while on treadmill. What do you want to do?
QUESTIONS: Is the wide tachycardia that is seen best in the chest leads, too irregular to be VT ( V entricular T achycardia )? — For more on the diagnostic significance of identifying AV dissociation in wide tachycardia — See ECG Blog #133 and ECG Blog #151. How certain are YOU of your answer?
milla1cf Fri, 05/17/2024 - 18:54 May 17, 2024 — Royal Philips , a global leader in health technology, is presenting new retrospective study results demonstrating the clinical and economic benefits of Philips’ AI-powered cardiac care solutions at the Heart Rhythm Annual Meeting in Boston (May 16-19).
Circulation, Volume 150, Issue Suppl_1 , Page A4143624-A4143624, November 12, 2024. Background:In diabetic ketoacidosis (DKA), cardiac complications such as QTc interval prolongation can pose a risk for ventricular tachycardia. QTc intervals were calculated using the Bazett, Fridericia, Hodges, Framingham, and Rautaharju formulas.
Most of the time with AV block — the atrial rhythm will be regular ( or at least almost regular — if there is an underlying sinus arrhythmia ). PEARL # 5: As noted above — today's arrhythmia appears to represent some form of 2nd-degree AV block. Figure-4: I needed to draw a laddergram.
Learning points : Takotsubo can lead to cardiac arrest from ventricular arrhythmia. Nossen highlights an important concept — namely pause -dependent precipitation of a malignant ventricular arrhythmia ( in this case Torsades de Pointes ).
Discover 2024’s Critical Advances in Cardiometabolic Care Here are some recent advances in cardiology: Aortic Disease : Moderate hypothermia during aortic arch surgery is effective, reducing the need for deep hypothermia.
Additionally, his cardiac telemetry monitor showed runs of accelerated idioventricular rhythm, a benign arrhythmia often associated with coronary reperfusion. He had multiple episodes of bradycardia and nonsustained ventricular tachycardia. As expected, the patient reported total resolution of pain by the time he got to the ED.
arrhythmia yield versus 69.1% in daily-symptom patients, demonstrating that greater symptom frequenc y does not necessarily reflect increased arrhythmia burden. arrhythmia yield versus 69.1% in daily-symptom patients, demonstrating that greater symptom frequenc y does not necessarily reflect increased arrhythmia burden.
Shortly after isoprenalin infusion was initiated, there were short runs of ventricular tachycardia. VT is the second most common presenting arrhythmia. Vaso or inotropic medications are not harmless, and can precipitate life threatening arrhythmias. She was started on isoprenalin (isoproterenol).
Volta Medical has announced it has entered into a Joint Development Agreement with GE Healthcare to enhance arrhythmia procedures with artificial intelligence (AI)-driven electrophysiology technologies. 1 Approximately 33 million patients worldwide are living with AFib.
== MY Comment , by K EN G RAUER, MD ( 8/30 /2024 ): == I was sent the ECG shown in Figure-1 — knowing only that the patient was being seen in the ED ( E mergency D epartment ). when the usual negative P wave deflection of sinus tachycardia is nowhere to be found in lead V1 )? This essentially rules in sinus tachycardia. (
There are a number of things to look for in an ECG that can hint at arrhythmia as the cause of an apparent seizure. There is a run of polymorphic ventricular tachycardia — which given the QT prolongation, qualifies as Torsades de Points ( TdP ). Below are some of the conditions to be aware of: Preexcitation Brugada syndrome.
There are three mechanisms of arrhythmia: automatic, re-entry, and triggered. The most common triggered arrhythmia is Torsades de Pointes. Automatic activity refers to enhanced pacemaking function (typically from a non sinus node source), for example atrial tachycardia. This has been discussed many times before on this blog.
However, he suddenly developed a series of malignant ventricular arrhythmias. This progressed to electrical storm , with incessant PolyMorphic Ventricular Tachycardia ( PMVT ) and recurrent episodes of Ventricular Fibrillation ( VFib ). Below are printouts of some of the arrhythmias recorded. What do you think?

However, the risk of arrhythmias following this procedure is reportedly high.
Circulation, Volume 150, Issue Suppl_1 , Page A4121234-A4121234, November 12, 2024. Background:Ischemia-related ventricular arrhythmia is the leading cause of death in patients after acute myocardial infarction (AMI).
milla1cf Tue, 03/05/2024 - 12:02 March 5, 2024 — Biosense Webster, Inc. , 2** Furthermore, the primary effectiveness endpoint (PEE) of acute pulmonary vein isolation and 12-month freedom from atrial arrhythmia recurrence (AF, Atrial Tachycardia, or Atrial Flutter) was 75.6%. Last accessed: January 2024.
Circulation, Volume 150, Issue Suppl_1 , Page A4142266-A4142266, November 12, 2024. Introduction:Supraventricular tachycardia (SVT) is common and poorly tolerated in patients who have undergone Fontan procedure. Atrial Tachycardia (70%) and Typical Atrial Flutter (65%) were the most common SVTs ablated.
The arrhythmia spontaneously converted before defibrillation was achieved. The patient was rushed to the nearest emergency department (non-PCI facility) for stabilization. Just prior to arrival he fell out of consciousness with the below ECG on the monitor. ECG #3 The above ECG shows a polymorphic VT at a rate of about 180 BPM.
Here is the only prehospital 12-lead: Sinus tachycardia, somewhat wide QRS, Ischemia Here is the first ED ECG: What is the rhythm here? Medics found patient in PEA arrest. He was resuscitated into a perfusing rhythm. He went in and out of arrest until arrival at the ED.
tim.hodson Thu, 09/05/2024 - 16:02 Sept. 2, 2024 – Medtronic recently shared long-term results from the global Extravascular Implantable Cardioverter Defibrillator (EV ICD) Pivotal Trial, reinforcing the performance and safety of the EV-ICD system.
We can see enough to make out that the rhythm is sinus tachycardia. Tachycardia is unusual for OMI, unless the patient is in cardiogenic shock (or getting close). A bedside ultrasound should be done to assess volume and other etiologies of tachycardia, but if no cause of type 2 MI is found, the cath lab should be activated NOW.
