Idiopathic malignant premature ventricular contractions

Trends in Cardiovascular Medicine, 2018
The presence of premature ventricular contractions (PVCs) in patients with structurally normal hearts was once considered a benign phenomenon. However, in susceptible patients, these "benign" or idiopathic PVCs may develop malignant potential and trigger ventricular fibrillation and result in sudden cardiac death.

Approach to Management of Premature Ventricular Contractions

Current Treatment Options in Cardiovascular Medicine, 2019
Premature ventricular contractions (PVCs) are arrhythmias with presentation ranging from asymptomatic and benign to symptomatic, frequent and capable of inducing cardiomyopathy. Work in the late 1970s-1980s showed that they could be representative of underlying coronary artery disease, hypertension, or left ventricular hypertrophy.

PRODUCTION OF PREMATURE VENTRICULAR CONTRACTIONS BY RAUWOLFIA

Journal of the American Medical Association, 1955
Alkaloids of Rauwolfia serpentina (Ophioxylon serpentinum) are currently enjoying great popularity for treatment of a wide variety of disorders, ranging from insanity to various forms of hypertension. While this drug has been in use for many years in India, a large pharmacological literature is not available. Allen and co-workers, in discussing its use

Premature ventricular contraction-induced cardiomyopathy

Current Opinion in Cardiology, 2016
There has been a resurgent interest in frequent premature ventricular contractions (PVCs) led by the novel concept that they may be a potential cause of, or at least contribute to, cardiomyopathy. This review evaluates recent advances in our understanding of PVC-induced cardiomyopathy.Recent studies have focused on identifying the predictors of PVC ...

Inhibition of Premature Ventricular Contractions by Desflurane

Journal of Cardiothoracic and Vascular Anesthesia, 2015
substantial increase in the number of procedures performed in the cardiac electrophysiology (EP) laboratory. Currently, no consensus or evidence-based recommendations exist regarding the type of anesthetic or anesthetic agents and drugs used to best facilitate radiofrequency (RF) ablation of tachyarrhythmias.

Advances in management of premature ventricular contractions

Journal of Interventional Cardiac Electrophysiology, 2012
Premature ventricular complexes (PVCs) are a common occurrence in clinical practice. The clinical presentation may range from asymptomatic to left ventricular (LV) dysfunction with congestive heart failure. The decision to suppress PVCs is largely based on the presence of symptoms, interference with other therapy (e.g., cardiac resynchronization ...

Premature ventricular contractions in normal children

The Journal of Pediatrics, 1978
To document the assumed benign prognosis of premature ventricular contractions in children, we followed 17 patients with PVCs and without other heart disease for a mean of seven years (range one to 19 years). Data were collected from the history, physical examination, 15-lead ECG, and treadmill exercise test.

Ventricular Tachycardia Due to Blanking of a Premature Ventricular Contraction

Pacing and Clinical Electrophysiology
ABSTRACT A 78‐year‐old man was evaluated for a non‐sustained ventricular tachycardia episode detected in a dual‐chamber pacemaker (Boston Scientific Essentio MRI EL L131) implanted for sick sinus syndrome. Blanking of a premature ventricular beat caused delivery of ventricular pacing in the vulnerable period triggering non‐sustained ...

Frequent Premature Ventricular Contractions

Cardiology in Review, 2015
Heart failure is common and is associated with significant morbidity and mortality. Identifying potentially modifiable risk factors for the development of ventricular dysfunction is important in both the prevention and the treatment of this condition.
