Background The presence of left bundle-branch block on the electrocardiogram may
conceal the changes of acute myocardial infarction, which can delay both its recognition and …

Background—Electrical storm, multiple temporally related episodes of ventricular tachycardia
(VT) or ventricular fibrillation (VF), is a frequent problem among recipients of implantable …

The purpose of this study was to determine the long-term outcome of patients with bundle
branch block (BBB) who have no clinical evidence of cardiovascular disease. Among 110,000 …

Our study suggests that certain changes in the ST segment in patients with endocardial right
ventricular pacing and chest pain are specific for the early diagnosis of AMI. Such signs may …

OBJECTIVES.: This study assessed the useful role of intracardiac mapping and radiofrequency
catheter ablation in eliminating drug-refractory monomorphic ventricular ectopic beats in …

The implantable cardioverter-defibrillator (ICD) is remarkably effective in preventing sudden
cardiac death in high-risk patients, but it also has the capacity to provoke or worsen cardiac …

Objectives. We sought to assess the outcome of patients with acute myocardial infarction (MI)
and bundle branch block in the thrombolytic era. Background. Studies of patients with …

Permanent cardiac pacing remains the only effective treatment for chronic, symptomatic
bradycardia. In recent years, the role of implantable pacing devices has expanded substantially. …

Sensing intrinsic cardiac electrical activity is essential for the function of pacemakers and
implantable cardioverter defibrillators (ICDs). Examples of undesired triggering or inhibition of …
