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 >>

Surface Electrocardiogram Recording: Baseline 12-lead and Ambulatory Electrocardiogram Monitoring.

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 >>

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 >>

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 >>

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 >>

Arrhythmias due to Inherited and Acquired Abnormalities of Ventricular Repolarization.

Emanuela T Locati, Giuseppe Bagliani, Franco Cecchi, Helou Johny, Maurizio Lunati, Carlo Pappone,

Several acquired and congenital disease conditions and many cardiac and noncardiac drugs affect ventricular repolarization and increase susceptibility to ventricular arrhythmias. Abnormal ventricular repolarization can be reflected on the surface ECG by prolonged or shortened QT interval, early repolarization, and abnormal T-wave configuration. Reduced outward K+ currents and abnormal or ... Read more >>
