Giangiuseppe Cappabianca, Sandro Ferrarese, Cassandra Tutino, Claudio Corazzari, Matteo Matteucci, Vittorio Mantovani, Andrea Musazzi, Roberto De Ponti, Cesare Beghi,

INTRODUCTION:the latest STS guidelines recommend concomitant AF ablation not only during mitral surgery (Class IA) but also during other-than-mitral cardiac surgery procedures (Class IB) in patients with preoperative AF. Conventional Cox-Maze III/IV procedures are performed on both atria (BA), but several studies reported excellent results with left atrial only (LA) ... Read more >>

Complex Arrhythmias Due to Reversible Causes.

Andrea Pozzolini, Teresa Rio, Margherita Padeletti, Roberto De Ponti, Fabio M Leonelli, Giuseppe Bagliani,

Abnormalities in cardiac rhythm are caused by disorders of impulse generation, conduction, or a combination of the 2, and may be life-threatening because of a reduction in cardiac output or myocardial oxygenation. Cardiac arrhythmias are commonly classified as tachycardias (supraventricular or ventricular) or bradycardias. Bradycardias are uncommon in the critically ... Read more >>

Hidden Complexity in Routine Adult and Pediatric Arrhythmias Interpretation: The Future of Precision Electrocardiology.

Fabio M Leonelli, Roberto De Ponti, Fabrizio Drago, Anwar Baban, Daniel Cortez, Massimo Griselli, Giuseppe Bagliani,

Classic ECG interpretation is based on identification of waveforms and deductive analysis of the electrical events the waveforms represent. The more in depth the understanding of electrophysiologic cellular interactions, the more precise the interpretation of ECG tracing. Surface ECG has limitations; yet, it is accurate in representing myocytes' pathologic behaviors. ... Read more >>

Margherita Padeletti, Giuseppe Bagliani, Roberto De Ponti, Fabio M Leonelli, Emanuela T Locati,

The 12-lead standard electrocardiogram (ECG) is a 10 second recording of human myocytes electrical activity. Filters and oversampling are necessary in order to acquire a smooth signal without distortion. ECG recordings may display ongoing arrhythmias, and some leads may be helpful in formulating the diagnosis. Advanced modalities of baseline ECG recording ... Read more >>

Challenges in Narrow QRS Complex Tachycardia Interpretation.

Roberto De Ponti, Jacopo Marazzato, Raffaella Marazzi, Matteo Crippa, Giuseppe Bagliani, Fabio M Leonelli,

Several arrhythmogenic substrates may generate narrow QRS complex tachycardia, frequently encountered in clinical practice. Some narrow QRS complex tachycardias, however, are sustained by an uncommon arrhythmogenic mechanism. Although rare, these forms should be taken into account in the differential diagnosis to avoid misdiagnosis and improper patient management. Dual atrioventricular node ... Read more >>

Electrocardiographic Approach to Complex Arrhythmias: P, QRS, and Their Relationships.

Fabio M Leonelli, Roberto De Ponti, Giuseppe Bagliani,

When faced with an electrocardiographic recoding of a complex arrhythmia, we often use inflexible algorithms or try to recall patterns already seen, which is often insufficient to explain the mechanisms of difficult bradycardias and tachycardias. We propose an approach to these situations where, starting from basic observations, the behavior of ... Read more >>

Alessandra Tordini, Fabio M Leonelli, Roberto De Ponti, Giuseppe Bagliani, Stefano Donzelli, Ludovico Lazzari, Chiara Marini, Marco M Pirrami, Giovanni Carreras,

Electrocardiographic algorithms are particularly useful to differentiate, in the presence of a wide complex tachycardia, between supraventricular aberrancy and ventricular tachycardias (VT). There are numerous limitations to the sensitivity and specificity of these algorithms including the presence of accessory pathways, use of antiarrhythmic drugs, congenital heart diseases, electrolytes impairments, and ...

Challenges in Bradicardias Interpretation.

Fabio M Leonelli, Roberto De Ponti, Giuseppe Bagliani,

Sinus node dysfunction or atrioventricular blocks are the causes of bradycardias. Diagnosis and management begin with evaluation of patient's hemodynamic status and diagnosis of bradycardia's cause. This is followed by an in depth evaluation of pathophysiology of the arrhythmia, its severity, and likelihood of progression. Implementing emergent measures depends on ... Read more >>

Giuseppe Bagliani, Josep Brugada, Roberto De Ponti, Graziana Viola, Paola Berne, Fabio M Leonelli,

Electrocardiogram (ECG) analysis trying to understand the mechanisms of QRS widening is often problematic. During WCTs, identification of P waves and atrioventricular relationship is often difficult and increasingly so if the number of recording leads available for examination is limited. For this reason, it is necessary to use every information ... Read more >>
