carpal tunnel syndrome (cts) is the most well-known and frequent form of median nerve entrapment, and accounts for 90% of all entrapment neuropathies. entrapment neuropathies of the ulnar nerve are relatively common with ulnar neuropathy at the elbow more prevalent than ulnar neuropathy at the wrist. the diagnosis of ulnar neuropathy at the elbow is usually confirmed in a relatively straight – ...

flecainide has been known to cause torsades de pointes (tdp) in patients with structural heart disease and its mechanism has been attributed to use-dependency. we present a patient with flecainide-induced tdp in the absence of any other precipitating factors.this case highlights potential reverse use dependence associated with flecainide resulting in tdp.

This open access text aims at giving you the simplest possible introduction to differential equations that are used in models of electrophysiology.

Cardiac electrophysiology is a rapidly expanding sub speciality of cardiology with ever increasing new information coming in every day, with quite a few journals devoted to it. Complexity of arrhythmias are sometimes puzzling for a busy cardiologist and so are electrophysiology studies. Electrophysiology for Clinicians is a concise book on basic concepts of cardiac electrophysiology for the bus...

ICH S7B guideline regulates the in vitro IKr assay in combination with in vivo QT evaluation prior to first-in-human administration. This guideline has been recommended for adoption by the regulatory bodies of 3 regions (Japan, USA and EU). To support compound development through cardiovascular safety assessment, Charles River Preclinical Services, Edinburgh (PCS-EDI) has developed and operates...

Catheter ablation is a first line treatment for many cardiac arrhythmias and is generally performed under x-ray fluoroscopy guidance. However, current techniques for ablating complex arrhythmias such as atrial fibrillation and ventricular tachycardia are associated with suboptimal success rates and prolonged radiation exposure. Pre-procedure 3D CMR has improved understanding of the anatomic bas...

objective considerable medical and legal debates have surrounded the prognosis and outcome of obstetrical brachial plexus injuries and obstetricians are often considered responsible for the injury. in this study, we assessed the factors related to the outcome of brachial plexus palsy. material & methods during 24 months, 21 neonates with obstetrical brachial plexus injuries were enrolled. elect...

methods in this article we checked the derived data from 20 relevant studies published during the last 20 years in international scientific literature at other country except iran and 10 studies from iran. the variables dose-area product (dap), fluoroscopy time, number of sequences and frames per sequence were collected for each ca, ptca, rfa and diagnostic electrophysiology and then the obtain...
