We studied isochronal maps of ventricular activation during ventricular arrhythmias induced by programmed premature stimulation in dogs 3-5 days after ligation of the left anterior descending coronary artery. The entire epicardial surface and selective intramural sites were recorded using a computerized multiplexing technique. The electrophysiologic data were correlated with the anatomic charac...
BACKGROUND Electrophysiologic studies including electromyography and nerve conduction studies play a role in the evaluation of carpal tunnel syndrome (CTS), despite evidence that these studies do not correlate with CTS-specific symptom scores. There is a lack of evidence comparing electrophysiologic data with general measures of function. METHODS Fifty patients presenting for CTS treatment ov...
BACKGROUND Withdrawal thresholds in the paw are lower in younger animals, and incision further reduces these thresholds. The authors hypothesized that these differences result in part from changes in intrinsic electrophysiologic properties of large neurons. METHODS Using isolated whole dorsal root ganglion, current clamping was performed to determine the electrophysiologic properties of large...

OBJECTIVES The purpose of this study was to define the incidence and predictors of implantable cardioverter-defibrillator (ICD) therapy in patients with arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C) after placement of an ICD for primary prevention. BACKGROUND Patients with a diagnosis of ARVD/C often receive an ICD for prevention of sudden cardiac death. METHODS Patient...
Transesophageal echocardiography (TEE) is widely used in the management of patients in intensive care units. The present study assesses the specific value of this technique in various categories of these patients. We reviewed 113 studies performed in 100 such patients for: suspected aortic dissection (25), suspected endocarditis (33), source of emboli assessment (19), hemodynamic instability (1...
Amyloidosis is caused by deposition of abnormal amyloid fibrils with the feared consequence end stage organ failure. Cardiac amyloidosis (CA) an increasingly recognized antecedent cardiomyopathy. CA classified into transthyretin variants (ATTRwt – wild type and ATTRv genetic variant) a light chain variant (AL); each these can be associated unique electrophysiologic abnormalities. Pacing indicat...
