The patient was a 71-year-old female with Torsade de Pointes (TdP) associated with idiopathic long QT syndrome. TdP and polymorphic nonsustained VT were frequently observed at bedside and an electrophysiologic study was performed. The QT (and QTU) interval was abnormally prolonged, and alteration of the QT interval was also recorded on the electrocardiogram. Monophasic action potential (MAP) fr...

A previously healthy 45-year-old male patient seen in the Chest Pain Clinic giving a classical history for angina having developed exertional central chest/left arm discomfort while training for a marathon. He had a past history of infrequent migraines but nil else of note. He had a family history of ischaemic heart disease in first degree relatives and was an ex-smoker, he was just on aspirin....

It is commonly accepted that the endocochlear DC potential (EP) of the cochlea is generated by electrogenic transport of potassium ion into the scala media from the marginal cells of the stria vascularis. In recent years, many models of the marginal cell have been developed in which the EP is generated by an electrogenic ion transport system localized in either the basal or apical membranes of ...

BACKGROUND Coronary slow flow (CSF) is a special coronary microvascular disorder. The pathogenesis and effective therapeutics of CSF remain unclear. This study aimed to evaluate the global and regional functions of the left ventricle (LV) and investigate the efficacy of nicorandil in patients with CSF. PATIENTS AND METHODS Thirty-six patients with CSF in the left anterior descending (LAD) bra...

Drug-eluting balloon (DEB) with angioplasty a paclitaxel-coated balloon catheter is an effective treatment option in patients with in-stent restenosis (ISR) after a drug-eluting stent (DES). We describe a case in which 'no-reflow' phenomenon developed after DEB angioplasty of a DES ISR lesion. Coronary flow was restored after intracoronary administration of nicorandil.
