If it is less than or equal to 0.5, it is classified as a
premature ventricular contraction signal.
(a) Pooled data for time to onset from ventricular fibrillation (VF) and
premature ventricular contractions (PVC).
2D-ECHO, Bi-dimensional echocardiogram; BMI, body mass index; CK, creatinine kinase; CRP, c-reactive protein; CV, conduction velocity; DCM-CD, dilated eardiomyopathy with conduction defect disease; EDMD, Emery Dreifuss Muscular Dystrophy; ECG, electroeardiogram; EMG, needle electromyogram; LMNA, laminA/C; LGMD, limb girdle muscular dystrophy; LVEF, left ventricular ejection fraction; METs, metabolic equivalents; MU, motor unit; MUGA, multigated acquisition; NE, nuclear envelope; PVC's,
premature ventricular contractionsDuring April 19-25, in addition to MI, nine other serious adverse events were reported: one case of respiratory distress, one case of coronary artery disease, one case of angina, one case of persistent fatigue, one case of
premature ventricular contractions, and four cases of headache (Table 2).
Two or three weeks following the patient's admission, he suffered increasing episodes of
premature ventricular contractions (PVCs) and bradycardia (a slow heart rate).
For the past 15 years I've known that I have a mild mitral valve prolapse (MVP), with
premature ventricular contractions (PVCs) that I can feel.
Excessive use can cause
premature ventricular contractions (Greden, 1974; Greden, Victor, Fontaine, & Lubetsy, 1980).
After resuscitation, pulmonary edema developed; the patient had a systolic blood pressure of 60 mm Hg, a pulse rate of 120 beats/min, and frequent
premature ventricular contractions. Electrocardiogram showed sinus tachycardia with frequent ventricular premature contractions and an acute extensive anterior myocardial infarction.
Kwon notes that palpitations may be signs of ectopic heartbeats, such as
premature ventricular contractions (PVC) and premature atrial contractions (PAC).
[5] Cardiac dysrhythmias commonly associated with MVP are nonspecific and may include both supraventricular (sinus tachycardia, atrial fibrillation, atrial flutter, junctional tachycardia) and ventricular (
premature ventricular contractions, ventricular tachycardia) dysrhythmias.
This raises the risk of irregular beats from the top chambers of the heart (such as atrial fibrillation, see previous page) or from the bottom chambers (
premature ventricular contractions or PVCs).
In addition, most cardiac monitors will include
premature ventricular contractions (PVCs) or other abnormal beats when calculating heart rate.
