The Impact of COVID-19 Outbreak on Syncope Units Activities in Italy: A Report from the Italian Multidisciplinary Working Group on Syncope (GIMSI).

The aim of our study was to evaluate the impact of the COVID-19 outbreak on Syncope Units (SUs) Activities in Italy. Data about types of SU activities and admissions were obtained from 10 SUs throughout Italy, certified by the Italian Multidisciplinary Working Group on Syncope (GIMSI), from 10 March 2020 to 31 December 2020 and compared with the same time frame in 2019. A remarkable reduction in overall non-invasive diagnostic tests (-67%; < 0.

Clinical spectrum of fascicular tachycardia.

Aims: Ventricular tachycardia spreading from the anterior or posterior division of the left bundle branch is generally called fascicular tachycardia (FT). We will present our experience with FT, a type of ventricular tachycardia not necessarily implying the absence of heart disease and/or sensitivity to selective antiarrhythmic drugs, but only particular routes of left ventricular depolarization.

Methods: Since 1981 we have had the opportunity to study 10 cases of FT (nine men and one woman; aged 28-77 years, mean ± SD 55 ± 18.

Severe ventricular dysrhythmias and silent ischemia during infusion of the antimetabolite 5-fluorouracil and cis-platin.

The antimetabolite 5-fluorouracil is frequently used in the therapy of various malignancies. Cardiotoxicity has frequently been described during treatment, but there is no common agreement on the need to perform cardiovascular monitoring of patients during 5-fluorouracil administration. We report the case of a young patient with an head-neck cancer on whom a continuous electrocardiogram recording was performed, documenting serious ventricular dysrhythmias in the presence of myocardial ischemia during 5-fluorouracil and cis-platin infusion.

Cardiac resynchronization therapy as an 'alternative' approach to a non-operable severe aortic stenosis with left ventricular dysfunction.

Severe symptomatic aortic stenosis (AS) is an indication for surgical replacement of the aortic valve in adults. Patients are often affected by comorbidities, and the surgical indication is sometimes problematic. Non-surgical techniques have been developed during the past few years, though their roles have not yet been established.

[Long QT and torsade de pointes in a patient with acquired human immunodeficiency virus infection in multitherapy with drugs affecting cytochrome P450].

In acquired human immunodeficiency virus (HIV) infection, a long depolarization period at ECG may be the consequence of cardiac complications due to viral myocarditis or cardiomyopathy or indirectly due to autonomic neuropathy, or sometimes resulting from pharmacological treatments. Several drugs administered for direct treatment of HIV disease or its complications, such as antiretrovirus, fluconazole, and antibiotics, may induce ventricular arrhythmias due to long QT prolonged depolarization period. Also methadone, frequently associated with HIV therapy to treat patients with opiate addiction, is described in the literature to have cardiac inotropic effects.
