Discrete sites of frequent premature ventricular complexes cluster within the infarct border zone and coincide with high frequency of delayed afterdepolarizations under adrenergic stimulation.

Heart Rhythm, 2021
BACKGROUND Sympathetic activation in ischemic heart disease can cause lethal arrhythmias. These are often preceded by premature ventricular complexes (PVCs), which could at cellular level, result from delayed afterdepolarizations. OBJECTIVE To identify

Diagnostic and prognostic significance of premature ventricular complexes in community and hospital-based participants: A scoping review

PLoS ONE, 2021
Background While there are published studies that have examined premature ventricular complexes (PVCs) among patients with and without cardiac disease, there has not been a comprehensive review of the literature examining the diagnostic and prognostic ...

Premature Ventricular Complexes and Development of Heart Failure in a Community-based Population

Heart, 2021
Objective A higher premature ventricular complex (PVC) frequency is associated with incident congestive heart failure (CHF) and death. While certain PVC characteristics may contribute to that risk, the current literature stems from patients in medical ...

Bigeminy and the bifid papillary muscle

Cardiovascular Ultrasound, 2010
Various structural anomalies of the left ventricular papillary muscles have been observed in recent years. Many of these have been linked to electrocardiographic aberrations.

Necklace pattern left ventricular noncompaction cardiomyopathy with plethora of paradoxic septal premature ventricular complexes: A case report and literature review

Heart and Mind, 2022
We report an extremely rare case of left ventricular noncompaction (LVNC) cardiomyopathy sparing the anterior ventricular wall in an interesting “necklace” pattern in parasternal short axis view in a 76-year-old female with frequent palpitation and ...

Delayed cardiac tamponade following catheter ablation of frequent premature ventricular complexes: a case report

BMC Cardiovascular Disorders, 2020
Background Cardiac tamponade is a potentially fatal complication after catheter ablation of ventricular arrhythmias. It often happens during or shortly after the procedure and needs urgent treatment.
