Objective To report the number of thromboembolic complications in a cohort of pediatric and young adult patients presenting with atrial fibrillation (AFib) or atrial flutter (AFl) while also assessing anticoagulation practice in a multicenter cohort of young patients with these arrhythmias.

This is a very typical ECG for Hypertrophic Cardiomyopathy. The most recent previous was 4 years prior, and was in the normal range) Elderly patients, and patients with cardiomyopathy (including HOCM), may have troponin values in this range chronically ("chronic myocardial injury"). WPW Cardiac arrhythmias ( including AFib ).

(Harvard University Heart Letter) A clinical polygenic risk score test for diseases ranging from atrial fibrillation (AFib) to breast cancer was piloted by scientists. Patients with obstructive hypertrophic cardiomyopathy who underwent surgical myectomy reported improved quality of life.

That said — distinction between "classic" HCM vs the apical HCM for m may be useful because: i ) ECG findings tend to be different ( Lyon et al — Europace 20:102-112iii, 2018 ) ; — ii ) Echo appearance is different when hypertrophy localizes to the apex; and , iii ) There is a significantly greater incidence of AFib with apical HCM.

As a result, in order to differentiate MAT from the much more commonly encountered irregularly irregular rhythm ( which is AFib ) — we need to be certain we are seeing multiple different P wave morphologies that are constantly changing. Clinically , the importance of recognizing MAT — is that treatment is different than the treatment of AFib.

The patient was diagnosed with stress cardiomyopathy. Widespread T wave inversions and prolongation of the QT interval is not uncommon in Takotsubo cardiomyopathy. The QTc then gradually shortened over the course of several days as is usual for stress cardiomyopathy. Potassium was 4,8 mmol/l. ( ref 3,5-4,6 mmol/l ).

OPTION Trial : LAAC after AFib ablation was associated with lower risks of major bleeding compared to oral anticoagulation. VANISH2 Trial : Catheter ablation as first-line therapy reduced VT episodes more effectively than antiarrhythmic drugs in ischemic cardiomyopathy patients. Access the full study. View the study.

The patient also has a history of AFib and HFmrEF ( = H eart F ailure with M inimally- R educed E jection F raction ). There is almost always the possibility of exceptions ( ie, prior infarction or cardiomyopathy that might result in a very abnormal baseline tracing ). Why was it Wrong to Think the Rhythm was AFlutter?

The QRS is wide in B — but the rhythm is irregularly irregular with no sinus P waves — so this most probably represents rapid AFib with an atypical RBBB/LPHB morphology. We now see that QRS morphology in lead II during sinus rhythm is similar to the QRS morphology in lead II during rapid AFib (beats #1-5 in lead II in A).

He had a h/o ischemic cardiomyopathy and right MCA stroke. As per Dr. Smith — this suggests that despite QRS widening, the rhythm in ECG #3 is AFib with a rapid ventricular response. FINAL PEARL #3: When AFib is fast — the rhythm may at first glance look like it is regular. Later, I obtained more clinical history.

They had a history of non-ischemic cardiomyopathy (EF 30%), as well as PCI with one stent. In most middle-aged patients with a history of cardiomyopathy, a WCT will usually be VT. Fragmentation suggests scarring (ie, from prior MI and/or cardiomyopathy ). Only AFib was induced during EP study.

The absence of any wall motion abnormality makes ischemic cardiomyopathy very unlikely. The new onset cardiomyopathy was thought to be due to both drug/alcohol use and to Tachycardia-Induced Cardiomyopathy.

TiCM is defined as the presence of a reversible form of LV dysfunction due solely to an increase in ventricular rate from any type of frequent or sustained tachycardia ( rapid AFib being the most common precipitating rhythm but TiCM has also been shown to arise from AFlutter, reentry SVT rhythms, ATach, frequent PVCs, episodes of VT ).
