ventricular ectopy

ventricular ectopy

A recent term for ventricular ectopic (premature) beats, also known as EXTRASYSTOLES. There are indications that ventricular ectopy during exercise may be due to perfusion defects in the heart muscle, and that frequent ectopic beats after exercise may be more significant indications of risk than when they occur during exercise.

This association is also seen with certain cardiovascular irregularities as well as diabetes: "Subclinical magnesium and potassium deficiencies are strongly associated with increased ventricular ectopy and arrhythmias.
Citing the most recent guidelines, symptomatic bradycardia with congenital AVB has been accepted as a Class I indication for pacemaker implantation in cases such as wide QRS escape and complex ventricular ectopy (9).
Radiofrequency Ablation (RFA) of ventricular ectopy has been postulated as a therapeutic approach in Brugada syndrome patients.
Has wide QRS-escape-rhythm, complex ventricular ectopy, or ventricular dysfunction.
This is also helpful as the physical irritation of ventricular myocardium by the ablation catheter, with resultant troublesome ventricular ectopy, is avoided.
In patients with clinically manifest coronary artery disease, clinical parameters such as reduced ventricular function, history of heart failure, frequent ventricular ectopy, inducible ventricular tachycardia on electrophysiologic studies, and abnormal autonomic function tests such as heart rate variability and abnormal microvolt T wave alternans are markers for an increased probability of sudden death (3).
51) suggested that the lowest hypoxemia level which was necessary to trigger a ventricular ectopy was as low as 60%.
Ventricular ectopy and ventricular fibrillation has been described(34).
Simantirakis et al [8] using a subcutaneously implanted loop recorder, investigated the impact of SRBD treatment by means of continuous positive airway pressure therapy and found a significant reduction in ventricular ectopy beats in 21 patients with moderate and severe SRBD after 8 weeks of this therapy, and no ectopy was recorded during the last 6 months of follow-up.
Frequent ventricular ectopy after exercise as a predictor of death.
Specifically, the study found that sleep-disordered breathing was associated with four times the odds of atrial fibrillation, three times the odds of nonsustained ventricular tachycardia, and almost twice the odds of complex ventricular ectopy, after adjustment for age, sex, body mass index, and prevalent coronary heart disease.
