Clinical Significance of Ventricular Premature Beats
- 29 Downloads
The Authors make some considerations about the clinical significance of ventricular arrhythmias and their relationship to contractile myocardial impairement. The presence of ventricular arrhythmias with depression of myocardial contractility even in a localised area can be the first sign of cardiomyopathy. The population of postinfarction patients may show a similar behaviour in the presence of a worsening of ischemic cardiopathy. Isolated arrhythmic events, even at higher degree of risk (Lown classes 4 and 5) do not necessarily imply a real worsening of the basic disease.
