The use of implantable cardioverter-defibrillators (ICDs) in octogenarians is poorly defined.

Electrocardiographic findings, device therapies, and comorbidities in octogenarian implantable defibrillator recipients.

Multiple pharmacological therapies currently in prevalent clinical use for cardiac diseases have antifibrotic properties. Spironolactone, a potent antifibrotic agent, is currently used for advanced heart failure. Therapies such as HMG-CoA reductase inhibitors (statins) and angiotensin-converting enzyme inhibitors (ACEi) also have antifibrotic properties. However, the effect of these medications on the ventricular arrhythmia phenotype is currently unknown. Therefore, we set out to define the ventricular arrhythmia rates in patients actively treated with such therapies.

Spironolactone therapy is associated with reduced ventricular tachycardia rate in patients with cardiomyopathy.

Shoulder pain and disability ipsilateral to the implant site is a common complication of cardiac rhythm device implantation, yet very little has been published about this morbidity. We designed a study to assess the potential benefit of a simple exercise protocol in preventing shoulder pain postoperatively.

Preventing shoulder pain after cardiac rhythm management device implantation: a randomized, controlled study.

The efficacy of implantable cardioverter defibrillators in reducing the risk of sudden cardiac death has been well established by several clinical trials. Several factors relating to device characteristics, patient attributes, and comorbidities should be considered when selecting the appropriate implantable cardioverter defibrillators for each patient. This review examines some of these issues.

Important Parameters for Implantable Cardioverter Defibrillator Selection.

The prevalence of atrial fibrillation (AF) in active astronauts is ≈5%, similar to the general population but at a younger age. Risk factors for AF include left atrial enlargement, increased number of premature atrial complexes, and certain parameters on signal-averaged electrocardiography, such as P-wave duration, root mean square voltage for the terminal 20 ms of the signal-averaged P wave, and P-wave amplitude. We aimed to evaluate changes in atrial structure, supraventricular beats, and atrial electrophysiology to determine whether spaceflight could increase the risk of AF.

Effects of Prolonged Spaceflight on Atrial Size, Atrial Electrophysiology, and Risk of Atrial Fibrillation.

Conduction abnormalities are known to occur after heart transplantation. In some cases, a permanent pacemaker is required. Conventional transvenous pacemakers can result in several complications, mainly related to the leads and device pocket. Leadless pacemaker technology was developed to overcome these issues. We report what we believe is the first US case of a leadless pacemaker implant (specifically in a heart transplant recipient) with the longest reported duration of follow-up.
