Heart rate recovery post-exercise as an index of parasympathetic activity.
The time constant (T) obtained by fitting post-exercise heart rate (HR) recovery to a first order exponential decay curve has been promoted as an index of parasympathetic activity. However,… Expand

A Leadless Intracardiac Transcatheter Pacing System.
BACKGROUND A leadless intracardiac transcatheter pacing system has been designed to avoid the need for a pacemaker pocket and transvenous lead. METHODS In a prospective multicenter study without… Expand

Warfarin in the prevention of stroke associated with nonrheumatic atrial fibrillation. Veterans Affairs Stroke Prevention in Nonrheumatic Atrial Fibrillation Investigators.
BACKGROUND Nonrheumatic atrial fibrillation is common among the elderly and is associated with an increased risk of stroke. We investigated whether anticoagulation with warfarin would reduce this… Expand

Provocation of bradycardia and hypotension by isoproterenol and upright posture in patients with unexplained syncope.
Neurally mediated hypotension and bradycardia are believed to be common causes of syncope. We used the "upright-tilt test" (duration, less than or equal to 10 minutes) with or without an infusion of… Expand

Deaths and cardiovascular injuries due to device-assisted implantable cardioverter–defibrillator and pacemaker lead extraction
Aims An estimated 10 000–15 000 pacemaker and implantable cardioverter–defibrillator (ICD) leads are extracted annually worldwide using specialized tools that disrupt encapsulating fibrous tissue.… Expand

Cardiac asystole: a manifestation of neurally mediated hypotension-bradycardia.
It has been proposed that prolonged cardiac asystole mimicking an episode of sudden cardiac death may occur as a manifestation of neurally mediated hypotension-bradycardia syndrome. To assess this… Expand

Role of transesophageal echocardiography in the detection of left atrial thrombus in patients with chronic nonrheumatic atrial fibrillation.
Transesophageal echocardiography was used to assess cardiac abnormalities associated with embolization in patients who had completed the Department of Veterans Affairs Cooperative Study of Stroke… Expand

Recovery from acute renal failure.
Acute tubular necrosis is the most common cause of acute renal failure making up two-thirds of such cases. Mortality is best correlated to basic disease. Surgery, particularly in the abdomen, carries… Expand

Effect of the antiarrhythmic agent moricizine on survival after myocardial infarction.
BACKGROUND The Cardiac Arrhythmia Suppression Trial (CAST) tested the hypothesis that the suppression of asymptomatic or mildly symptomatic ventricular premature depolarizations in survivors of… Expand

Single-chamber cardiac pacing with activity-initiated chronotropic response: evaluation by cardiopulmonary exercise testing.
In this study, sequential cardiopulmonary exercise testing was used to assess the physiologic benefits of a single-chamber ventricular pacing system that utilizes a piezoceramic sensor to adjust… Expand
