In CHF patients, HRV indexes related to parasympathetic function are valid and clinically useful tools to select and follow-up those candidates that could experience superior functional improvement after ET.

Brugada phenocopies represent some unusual clinical cases with identical characteristics to Brugada syndrome (BrS) elicited by various clinical circumstances. We report the case of a woman exhibiting "Brugada Phenocopy" during an acute anterior myocardial infarction, highlighting differential diagnosis with true BrS and discussing possible mechanisms underlying its dynamic ECG pattern.

Pulmonary hypertension significantly changes biventricular anatomy and physiology, frequently evolving to clinical deterioration and right ventricular failure. The case of a woman developing atrial arrhythmias complicating dipyridamole stress in concomitance with scintigraphic “D-shaped” left ventricle is briefly reported. Although rare, our finding may suggest that nonselective vasodilators should be used with caution in this clinical setting.

Tako-tsubo disease (TD) is an unusual and paradigmatic clinical entity of unknown pathophysiology characterized by acute apical dysfunction usually triggered by physical or emotional stress. We describe the case of a woman with TD presenting early myocardial perfusion defects with transient dilatation and systolic dysfunction of left ventricle in gated-SPECT myocardial perfusion imaging, discussing the more likely mechanisms suggested by these functional findings.
