Background Hypertrophic cardiomyopathy (HCM) is commonly associated with atrialfibrillation (AF), but its impact on outcomes in real-world practice is uncertain. The aim of the study was to evaluate the clinical profile and prognosis of patients with HCM and AF. Methods Overall, 1739 adult patients with HCM (40.9%
Medics found him in ventricular fibrillation. He was defibrillated, but they also noticed that he was being internally defibrillated and then found that he had an implantable ICD. He was unidentified and there were no records available After 7 shocks, he was successfully defibrillated and brought to the ED.
For the past four decades, implantable cardioverter defibrillator (ICD) therapy has become the standard of care for preventing sudden cardiac death in high-risk individuals. Patients with ICDs who experience atrialfibrillation (AF) have a higher risk of stroke, heart failure, and mortality.
16, 2025 Primary results from the DEFINE AFib clinical study show the Medtronic LINQ family of insertable cardiac monitors (ICM), paired with a novel algorithm, were able to detect atrialfibrillation episodes and properly risk stratify patients as high risk prior to an AF-related healthcare utilization 80% of the time. 2024, May 15).
Rate vs Rhythm Control in AtrialFibrillation Rate vs rhythm control as a management strategy in atrialfibrillation has been a long standing topic for debate. EAST-AFNET 4 trial had 2789 patients with early atrialfibrillation and cardiovascular conditions [8]. years of follow up per patient. N Engl J Med.
Here was his initial ED ECG: There is atrialfibrillation with a rapid ventricular response. ST depression is common BOTH after resuscitation from cardiac arrest and during atrial fib with RVR. Not all patients with ventricular fibrillation necessarily need emergent angiography. A middle-aged male had a V Fib arrest.
The wearable cardioverter defibrillator (WCD) is becoming a more and more widely used instrument for the prevention of sudden cardiac death of patients either with a secondary prevention implantable cardioverter defibrillator indication or with a transient high risk of sudden cardiac death.
Subclinical atrialfibrillation (SCAF) is commonly detected in older individuals with an implanted pacemaker or defibrillator. The evolution of implantable and wearable cardiac monitors has increased interest in screening for SCAF in a broader population of individuals at increased risk of stroke.
“Therefore, we have made the decision to offer only DX technology for new patients needing a single-chamber ICD, providing equivalent therapies along with additional atrial monitoring data, as recommended by current guidelines.” For more information: [link] References: Thomas G, Choi DY, Doppalapudi H, et al. Margolis G, et al.
Her Apple Watch suddenly told her that she is in atrialfibrillation. Patients with healthy AV nodes who are not on AV nodal blockers and who are not hyperkalemic should have a rapid ventricular response if they have paroxysmal Atrialfibrillation. Exam was completely normal except for an irregular heart rate.
BackgroundScreening for atrialfibrillation (AF) may reveal incidental arrhythmias of relevance. Journal of the American Heart Association, Ahead of Print. Subsequently, 8 patients underwent pacemaker implantation, 1 for sinus node dysfunction (post‐AF conversion pause of 9 seconds) and 7 for advanced AVB. of our cohort patients.
Abstract Introduction Wearable cardioverter defibrillator (WCD) is utilized in patients with assumed but not yet confirmed risk for sudden cardiac death (SCD). Many of these patients also present with atrialfibrillation (AF).
Background:Device-detected atrialfibrillation (AF) (also known as subclinical AF or atrial high-rate episodes) is a common finding in patients with an implanted cardiac rhythm device and is associated with an increased risk of ischemic stroke. Circulation, Ahead of Print.
Such as atrialfibrillation or sinus rhythm with extrasystoles. Answer shown below: This can be even more challenging with atrialfibrillation where the only thing you can rely on is careful morphologic inspection. Sometimes this type of artifact happens in atrialfibrillation and it can be very challenging.
We conducted this systematic review and meta-analysis to evaluate safety outcomes including risk of ventricular arrhythmias, new onset atrialfibrillation, Implantable Cardiac defibrillators (ICD) shocks, QRS duration reduction, heart failure hospitalizations and mortality.
The most common arrhythmia, atrialfibrillation , will affect approximately 12.1 Pacemakers and implantable cardioverter defibrillators (ICDs) are the standard of care to regulate a patient’s irregular heartbeat.
AF, atrialfibrillation; ICD, implantable cardioverter defibrillator; ILR, implantable loop recorder. ABSTRACT Introduction Little is known about age and clinical intervention after implantable loop recorder (ILR) insertion. This study investigated the association between age and clinical intervention after ILR implantation.
Medical therapy by and large is not that effective in Brugada syndrome, and the most recommended therapy if you have a definite diagnosis of Brugada syndrome, is implantation of an implantable cardioverter defibrillator for saving from sudden death which can occur due to life threatening ventricular arrhythmias in Brugada syndrome.
The clinical outcomes including mechanical ventilation time, intensive care unit stay time, hospital stay time, postoperative stroke, postoperative new-onset atrialfibrillation, postoperative heart failure requiring intra-aortic balloon pump mechanical circulation support, and in-hospital mortality of both are comparable.
We describe a case of ventricular pacemaker spikes delivered on the T wave causing PMVT.Case:A 53-year-old female with CAD s/p stent, postpartum cardiomyopathy s/p Bi-V CRT-D (Boston Scientific G124), and paroxysmal atrialfibrillation presented for elective endoscopy and colonoscopy to evaluate her dysphagia and abdominal pain.
She was found to be in ventricular fibrillation and was defibrillated 8 times without a single, even transient, conversion out of fibrillation. Fine ventricular fibrillation She received 2 mg epinephrine, 150 mg amiodarone and underwent chest compressions with the LUCAS device. at the time of the ECG. Mg was 1.6.
Note: Due to the limited number of normally conducted beats — it is hard to be sure whether the underlying rhythm is sinus with baseline artefact or atrialfibrillation. After resuscitation and defibrillation , there were no more episodes of TdP. Below is the patient’s 12 lead ECG following defibrillation.
In addition to regression-based risk models, the predictive ability of different machine learning-based models was evaluated in the same cohort. Recursive feature elimination was employed to identify the most relevant features in predicting the risk of mortality.
The rhythm now is atrialfibrillation. The arrhythmia spontaneously converted before defibrillation was achieved. A repeat ECG was recorded about 15 minutes after the initial ECG. What do you think has happened and what is the most likely diagnosis? ECG #2 Again there is a wide complex QRS due to RBBB and LAFB.
Artifact can obscure the rhythm or cause misdiagnosis of rhythms such as atrialfibrillation, ventricular tachycardia, and ventricular fibrillation. As worrisome as the initial recording in leads I and II look — a glance at lead III should immediately reassure us that defibrillation is not needed!
She was successfully revived after several rounds of ACLS including defibrillation and amiodarone. Conduction and refractoriness alternans may be seen with WPW-related as well as AV Nodal-dependent reentr y tachycardias — atrialfibrillation — acute pulmonary embolus — myocardial contusion — and severe LV dysfunction.
The disorder is rare — but it takes on importance as a potential cause of atrial and ventricular arrhythmias, including cardiac arrest. Treatment is by ICD ( implantable cardioverter defibrillator ). Males with a QTc ≤330 ms — and females with a QTc ≤340 ms are defined as having SQTS , even if they are asymptomatic.
The patient was put on Extracorporeal Life Support in the ED 3 hours after initial resuscitation, the core temp was 30° C and the patient was defibrillated with a single attempt. On arrival, CPR was continued and core temperature was measured at 18° C (64.4° A 12-lead ECG was recorded: There is sinus rhythm with RBBB and right axis deviation.
It was reportedly a PEA arrest; there was no recorded V Fib and no defibrillation. The rhythm is atrialfibrillation. Initial ROSC was obtained, during which this ECG was obtained: What do you think? Meyers interpretation: This is a complicated interpretation made even more so by the fact that it is immediately post ROSC.
At cath, he immediately had incessant Torsades de Pointes requiring defibrillation 7 times and requiring placement of a transvenous pacer for overdrive pacing at a rate of 80. There is atrialfibrillation. He was given amiodarone and lidocaine load and drip and K and Mg drips. After pacing, there was no recurrence of Torsades.
Abstract Introduction The pivotal study of the extravascular implantable cardioverter-defibrillator (EV ICD) recently demonstrated primary efficacy and safety endpoints comparable to previous ICD systems. No differences were noted by sex, atrialfibrillation, or the experience of ICD shock. vs. 46.8 ± 9.1 respectively, p = .020)
Subsequently, a transvenous implantable cardioverter-defibrillator (ICD) was implanted because he still had several episodes of bidirectional VT. Despite a good compliance to medication, the patient still had exercise induced VT episodes with new onset of atrialfibrillation.
The disorder is rare — but it takes on importance as a potential cause of atrial and ventricular arrhythmias, including cardiac arrest. Treatment is by ICD ( implantable cardioverter defibrillator ). Males with a QTc ≤330 ms — and females with a QTc ≤340 ms are defined as having SQTS , even if they are asymptomatic.
2:34 PM, following right heart catheterization She then went into atrialfibrillation with complete heart block and junctional escape rhythm prompting placement of transvenous pacemaker. Several 200 J shocks did not terminate the VF, so a second defibrillator was applied for double sequential defibrillation with 400 J.
Here is a representative CXR from a different patient showing a typical CRT-D The blue dotted line overlies the right atrial lead The red dotted line overlies the RV lead. This is the shock coil and identifies this device as a defibrillator. CRT-D is cardiac resynchronization therapy with defibrillation capability, like the CXR above.
