The electrocardiogram (ECG) is a valuable tool for assessing the cardiac conduction system. The measurements routinely obtained with ECG include heart rate, PR interval, QRS duration and the QT ...

Current guidelines support the use of cardiac resynchronization therapy (CRT) in patients with heart failure and a prolonged QRS interval (≥120 ms); however, tissue Doppler imaging has shown that some ...

Current guidelines from the American College of Cardiology and the American Heart Association recommend cardiac resynchronization therapy (CRT) for patients with NYHA class III or IV heart failure ...

New Orleans, LA - Cardiac resynchronization therapy (CRT) may reverse ventricular remodeling and improve LVEF in subgroups of HF patients for whom there are few prospective data supporting a benefit, ...

Cardiac-resynchronization therapy (an advanced feature of pacemakers and ICDs manufactured by Medtronic, Boston Scientific, St. Jude Medical, Biotronik, and Sorin) has been shown to be beneficial in ...

Presenter: Jeanne E. Poole, MD, University of Washington (Seattle) for the SCD-HeFT Investigators The high incidence of sudden cardiac death (SCD), particularly in patients with impaired left ...

QRS interval widening appears to be highly specific for the diagnosis of hyperkalemia in patients with end-stage kidney disease. ECG changes, in general, have poor sensitivities for hyperkalemia in ...

TO THOSE with extensive electrocardiographic experience, especially if it includes a large proportion of young adults, the finding of the pattern of a short PR interval and a prolonged QRS complex ...

A study among almost 50,000 people worldwide has identified DNA sequence variations linked with the heart's electrical rhythm in several surprising regions among 22 locations across the human genome.

ECG Findings May Identify Transplant Candidates at Higher Death Risk PHILADELPHIA—Abnormalities revealed by electrocardiography (ECG) may predict which patients undergoing evaluation for a renal ...

A RECENT review of experience with the syndrome of short PR interval and abnormal ventricular complex occurring in otherwise healthy persons prone to paroxysmal tachycardia disclosed that a third of ...
