Ventricular ectopics, also known as ventricular extrasystoles, premature ventricular contractions or complexes (PVC) and ventricular premature depolarisations (VPD) are beats arising from within the ventricles.
Three months later the patient was better and the cor- ticosteroid side effects were signif- icantly decreased. The number of polymorphic ventricular ectopic beats, couplets, and triplets were significantly reduced, and only 1 episode of nonsustained ventricu- lar tachycardia (7 beats, rate 140 ...
After implantation of hEHTs or cell-free constructs, ventricular arrhythmias (premature ventricular contractions, couplets, triplets and non-sustained ventricular tachycardia) were observed in animals of both groups. The fraction of animals with the respective arrhythmias as well as the rate of ar...
Using simple terms, explain how the contraction of the atria and ventricles is controlled by the cardiac conduction system. What is the difference between PVCs and ventricular Couplets and triplets? What is an ECG or an EKG? Discuss the events of a typ...
There was a significant reduction in the incidence of atrial premature complexes (APC) of 46.9%; ventricular premature complexes (VPC) of 67.8%; couplets were reduced by 71.85%, and triplets had entirely disappeared in the fish oil group. Taking fish oil supplements can prevent dangerous arrhythmi...
What is the difference between PVCs and ventricular Couplets and triplets? What is atrial diastole, and what is ventricular diastole? How do these alternate in the cardiac cycle? Why is the left ventricle of the human heart thicker than the right ventricle? How do the right and lef...
(VA) undergoing competitive sport eligibility screening.Methods We enrolled 65 athletes with documented ventricular arrhythmias as follows: 1) frequent PVB at 24-hour ambulatory ECG monitoring (>100 PVB/24h); 2) polymorphic PVB; 3) repetitive PVB (couplets, triplets, or nonsustained ventricular ...
In patients with SBDs, ventricular arrhythmias (couplets, triplets, short runs) were recorded simultaneously by Holter ECG and differentiated in episodes with and without disordered breathing. An apnea-associated arrhythmia index (AI) was defined as the number of ventricular arrhythmias occurring ...
Holters without PVCs or with more frequent ectopy (couplets, triplets, or nonsustained ventricular tachycardia) were excluded. Clinical and adverse event (AE) data (major adverse cardiovascular event or new/worsening heart failure) were gathered from chart review. Data was analyzed by PVC frequency ...
MethodsWe performed a retrospective cohort study of patients ≥18 years old referred to our institution for 24-hour ambulatory Holter monitoring between July 1, 2008 and December 31, 2009. Holters without PVCs or with more frequent ectopy (couplets, triplets, or nonsustained ventricular tachycardia)...
