High Morbidity and Mortality in Patients Admitted With a First-Episode Electrical Storm
Investigators assessed the burden of arrhythmia recurrence and in-hospital outcomes in patients hospitalized for electrical storm.
Tachycardia
Long-Term Performance, Safety of First Modular Cardiac Rhythm Management System
Researchers from a preclinical trial examined safety and performance of a 2-part cardiac rhythm management system, consisting of a leadless pacemaker and S-ICD.
Modified vs Standard Valsalva Maneuver Superior for SVT Conversion to Sinus Rhythm
Researchers compared the modified Valsalva maneuver to the standard method to assess efficacy and safety for converting SVT to sinus rhythm.
Cardiac Arrhythmias Rose During the 2016 Presidential Election
Researchers sought to determine whether the stress of a contentious political election increases the risk of arrhythmia in patients with known susceptibility.
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.
Active Myocarditis May Predict VT Recurrences After VT Ablation
Active myocarditis stage was found to predict the recurrence of ventricular tachycardia (VT) in patients with myocarditis undergoing VT ablation.
Navigation System With Nonfluoroscopic Approach Promising for Reduced Radiation Exposure During SVT Arrhythmia Ablation
The RhythmiaTM 3D mapping system coupled with a new nonfluoroscopic approach that reduces exposure to radiation was found to be safe, effective, and well tolerated during arrhythmia ablation procedures.
FOCUS May Be Useful for Ruling Out Pulmonary Embolism in Patients Presenting to the ED With Abnormal Vital Signs
In patients with abnormal vital signs presenting to the emergency department who are suspected of having a pulmonary embolism, a negative focused cardiac ultrasound examination may be associated with reduced odds of a pulmonary embolism diagnosis.
ECG Limb Lead Algorithm Sensitive, Specific for Wide Complex Tachycardia Diagnosis
Investigators assessed the diagnostic value of a new ECG algorithm according to the morphologic traits of the QRS on the limb leads.
Ventricular Tachycardia Recurrence With Deceleration Zone-Guided Targeted Ablation
A novel voltage-independent high-density mapping display can identify the functional substrate for ventricular tachycardia during sinus rhythm and guide targeted ablation.
