  2019-05-29

  

  T-wave alternans is a periodic beat-to-beat variation in the amplitude or morphology of the T wave on electrocardiography (ECG) (Fig. 1). Beat-to-beat T-wave alternans is considered to reflect increased dispersion of ventricular repolarization, and it is known to often precede the development of let

  After permanent pacemaker implantation, the 12-lead electrocardiogram revealed that the pacing spike appeared at the same time as the P wave and narrow QRS complexes with AV conduction (Fig. 4). This finding demonstrated effective enforcement of the left atrial pacing. The patient had no postoperati

  2019-05-29

  

  The renin-angiotensin system plays a crucial role in atrial fibrosis, which is a key pathological consequence of AF. Genes encoding 3 molecules related to the renin-angiotensin system, including angiotensin-converting enzyme (ACE), angiotensinogen, and angiotensin type 1 receptor (AT1R), are associa

  Conclusions Conflict of interest Introduction Radiofrequency (RF) catheter ablation is an established method of therapy for symptomatic supraventricular tachycardia (SVT). It has gained widespread acceptance for the treatment of accessory pathways in pediatric SVTs [1]. Accessory pathways a

  Preamble The J-wave syndromes (JWSs), consisting of the Brugada syndrome (BrS) and early repolarization syndrome (ERS), have captured the interest of the cardiology CGP-41251 over the past 2 decades following the identification of BrS as a new clinical entity by Pedro and Josep Brugada in 1992 [1].

  Thomas Hoeksema, por su parte, explica la paradoja del título del siguiente modo: “la destrucción (fuego) está moderada por la estabilidad y la armonía (reposo). La relación entre estas dos fuerzas es multidimensional y dialéctica”. Para Hoeksema, el segundo volumen poético de Pacheco se debe entend

  Much previous work highlights the rapid increases in DAH in the past decade, but in , Katherine Floyd and colleagues report that, in the case of tuberculosis, growth in domestic financing has been equally impressive. Their findings are convincing, especially in view of the fact that their study mig

  2019-05-29

  

  The approach used, of estimating effectiveness relative to a matched counterfactual, can be regarded as an attempt to reach the ideal estimation of relative risk, namely the comparison of a population to itself with the exposure removed. However, it is not possible to know exactly what would have ha

  2019-05-29

  

  Vaccines for rotavirus and cholera—the two diseases with the highest child mortality rates and a significant fraction of the global diarrhoeal burden—are at preliminary stages of implementation. The use of vaccination as a global primary-prevention strategy can also be rapidly strengthened with the

  2019-05-28

  

  A decreasing trend in CRT-D implantation has been reported recently, based on the database from the National Inpatient Sample in the USA [20]. They found that advancing age and an increasing comorbidity burden were associated with a reduced likelihood of CRT-D, and speculated that the decline in CRT

  Para ofrecer una idea del carácter de la revista, se analizan los textos que publicó Homero Garza en esa época. En su poesía la brisa tiene arterias, el agua, células, la voz se alimenta de fantasmas, el alma posee corteza, el llanto, piel, el letargo eleva espigas, las palabras tienen dientes de as

  Stigma and discrimination experienced by sex workers, injection drug users, and men who have sex with men is tough to tackle. Responses need to be tailored to very different circumstances and require interventions on several levels: policy, societal, health system, and individual. There is no magic

  Two fundamental objections to the conclusion that mass deworming for helminths has no benefits and could therefore be abandoned have been repeatedly raised. First, the underlying studies might have been insufficient to detect benefits, because the follow-up for most studies was too short to detect h

  The primary tool in the pharmacological management of PTSD is the use of selective serotonin reuptake inhibitors [55,56], but positive response rates are generally limited. In addition, non-pharmacological treatment such as CBT has been shown to be effective for PTSD [57]. Psychological distress

  Early recognition of ICD lead malfunction is desirable to prevent the life-threatening consequences of lead failure. Recent reports indicate that the majority of patients with ICD lead failure experience inappropriate ICD therapies, often as the presenting problem [4,6]. Regular device interrogation
