Disease relevance of Cardiac Complexes, Premature

 

Psychiatry related information on Cardiac Complexes, Premature

  • The patient had serious psychiatric problems; the ventricular premature beats were provoked by psychophysiologic stress, increased during REM sleep, were reduced by meditation, and were controlled by beta-adrenergic blockade, phenytoin and digitalization [6].

Anatomical context of Cardiac Complexes, Premature

  • In the rat coronary artery ligation model, disopyramide (class I), amefalone and melperone significantly (P less than 0.05) reduced the number of extrasystoles [20].
  • The accelerated inactivation time course of HERG/MiRP1(V65M) channels may decrease I(Kr) current density of myocardial cells, thereby impairing the ability of myocytes to repolarize in response to sudden membrane depolarizations such as extrasystoles [21].
  • Accuracy of the value <0 msec (obtained by subtracting the time interval between high right atrium and His-bundle atrial activation during atrial premature beats from that obtained during sinus rhythm) for discriminating the superior vena cava or upper portion of the crista terminalis from the pulmonary vein (PV) foci was 100% [22].
  • On the other hand, low doses of lidocaine caused speeding of early extrasystoles, i.e., coupling intervals (less than 250 ms) in the Purkinje system but not in the myocardium [23].
  • Lithium and KBR effects particularly for the extrasystole can be explained through the inhibition of Ca entry via Na-Ca exchange giving support to the participation of the Na-Ca exchanger in the Ca influx from the extracellular space [24].
 

Gene context of Cardiac Complexes, Premature

  • The plasma ANP level was significantly higher in patients with rather than without PAF attacks (75 +/- 41 vs. 54 +/- 60 pg/ml, p = 0.01), although there were no significant differences in age, left atrial dimension or high grade atrial premature beats between the groups [25].
  • Prognostic significance of heart rate turbulence following ventricular premature beats in patients with idiopathic dilated cardiomyopathy [26].
  • Patients with COPD had higher rate of ventricular premature beats (VPBs) as compared to control subjects (924 +/- 493 beats vs 35 +/- 23 beats, p = 0.009) [27].
  • Isolated ventricular premature beats and runs of slow ventricular rhythm with H(2)O(2) more frequently occurred in HF compared to SHAM despite an increased antioxidant capacity including Cu/Zn and Mn superoxide dismutase, catalase, glutathione reductase, and glutathione peroxidase [28].
  • However, with the addition of each successive premature beat, the HPS-RRP of the postextrasystolic beat alternated between lower and higher values, in a manner dependent on whether there was an odd or even number of premature beats [29].
