Prognostic significance of ventricular premature depolarizations measured 1 year after myocardial infraction in patient with early postinfarction asymptomatic ventricular arrhythmia

Abstract

The prognostic value of ventricular premature depolarizations observed 1 year after a myocardial infarction may be significant even in a sample selected for frequent ventricular premature depolarizations observed early after the event.

Radiofrequency catheter ablation of premature ventricular complexes from right ventricular outflow tract improves left ventricular dilation and clinical status in patients without structural heart disease

“…The presence of PVC has been found to be an independent risk factor for sudden death (11), especially in patients after myocardial infarction (12,13). Many patients with PVC often experience disabling symptoms and sometimes need long-term antiarrhythmic medications.…”

A case of ventricular fibrillation triggered by ventricular premature depolarizations exiting from different sites of the Purkinje network

“…VPD-triggered VF post MI has been previously described in the literature 1, 2, 3, 4, 5. The observed characteristics of the triggering VPDs include varying frequency, a coupling interval that is not particularly short (391 ± 48 ms), and a site of origin that is typically at the scar border and characterized by the presence of Purkinje potentials.…”

“…Ventricular premature depolarizations (VPDs) frequently occur de novo after a myocardial infarction (MI) and have been associated with arrhythmogenic sudden cardiac death 1, 2, 3. The understanding of the mechanisms underlying the initiation of the VPDs and its relationship to ventricular fibrillation (VF) in these patients is deficient 4 .…”

Tachycardiomyopathy Induced by Ventricular Premature Complexes: Complete Recovery after Radiofrequency Catheter Ablation

“…Although the presence of VPCs has been found to be an independent risk factor for sudden death occurring for the patient who is in a post-myocardial infarction status, isolated VPCs are known to be the most common and benign arrhythmia that doctors encounter in routine examinations21, 22). Further, there is only minimal risk of VPCs, and especially right ventricular extrasystoles, in the patients without structural heart disease23).…”
