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.
Tachycardia
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.
COPD May Predict Mortality in Ventricular Tachyarrhythmias, Sudden Cardiac Arrest
The presence of COPD is linked to higher all-cause mortality and cardiac death at 24 hours in high-risk patients who present with ventricular tachyarrhythmias and sudden cardiac arrest.
Hypothyroidism Predicts Atrial Tachyarrhythmia After AF Catheter Ablation
Patients with higher levels of thyroid-stimulating hormone were more likely to experience atrial tachyarrhythmia after catheter ablation for atrial fibrillation.
A 56-Year-Old Man With Flu-Like Symptoms Presents With Palpitations
A 56-year-old man with improved flu-like symptoms, but marked shortness of breath and palpitations, presents to an urgent care center.
