Catheter Ablation in Combination With Vein of Marshall Ethanol Infusion for Persistent AF

Catheter ablation was found to be associated with greater rates of freedom from AF or atrial tachycardia in patients with persistent AF, when performed in combination with vein of Marshall ethanol infusion vs alone.

Catheter Ablation May Be Superior to MRC for Improving LVEF in Persistent AF With Systolic Heart Failure

Catheter ablation was found to be superior to medical rate control for improving LVEF long term in patients with atrial fibrillation and systolic heart failure.

Beta-Blockers for Heart Rate Control in Sepsis-Associated Atrial Fibrillation

Treatment with beta-blockers vs amiodarone, calcium channel blockers, or digoxin was associated with improved heart control at 1, but not 6 hours in patients with sepsis and atrial fibrillation.

QTc Interval Prolongation After Admission for COVID-19

Prolongation of the QTc interval was found to be prevalent after 7 days of hospitalization for COVID-19.

Ventricular Tachycardia Substrate Ablation During Sinus Rhythm Associated With Few Complication, Low Mortality

Substrate ablation during sinus rhythm was found to be associated with low rates of procedural complications and early mortality.

COALITION II Study: Adding Azithromycin to Severe COVID-19 Care With Hydroxychloroquine Does Not Improve Outcomes

Study authors assessed whether azithromycin in addition to a hydroxychloroquine regimen shows positive results in clinical improvement or mortality reduction in patients hospitalized with severe COVID-19.

Low T/R Ratios in Type-1 Brugada Pattern May Predict VF, Sudden Cardiac Arrest

The risks for ventricular fibrillation or sudden cardiac arrest were found to be associated with low T/R ratios at leads II and V5 in patients with spontaneous type-1 Brugada pattern.

Higher Levothyroxine Doses Linked to Afib in Older Patients

To evaluate the association, the study authors utilized healthcare databases from Ontario, Canada to identify adults 66 years of age and older with no history of AF who filled at least 1 prescription for levothyroxine.

Ethanol Infusion May Prevent Recurrence of Refractory Ventricular Arrhythmia

Retrograde coronary venous ethanol ablation may prevent the recurrence of arrhythmias in the long-term in patients with ventricular arrhythmias refractory to drugs and radiofrequency ablation.

Elevated Cardiac Troponin I Level May Predict Adverse Outcomes in PSVT With a History of CAD

Elevated cardiac troponin I levels had prognostic value for paroxysmal supraventricular tachycardias only when the condition was associated with a history of coronary artery disease.
