“…En consecuencia, entre los factores que pueden elevar la motivación hacia la práctica del ejercicio físico en edades adolescentes se encuentran: la presión de grupo, algunos videojuegos, el acceso fácil a un gimnasio, dirección inicial por un entrenador experto, la variedad de actividades, deportes en equipo, participación de los apoyos familiares y entre compañeros (Peeters et al, 2012), o la sensación de satisfacción después de la pérdida de peso (Vergara et al, 2012). De hecho, los factores motivadores más importantes parecen ser el grupo de amigos, el entrenador y la escuela (Kulavic, Hultquist & McLester, 2013).…”

ResumenEl presente trabajo tiene como objetivo identificar las motivaciones que llevan a los adolescentes a incrementar la práctica del ejercicio físico. Para ello, se aplicó el cuestionario de Autionforme de Motivos para la Práctica de Ejercicio Físico (AMPEF) a 342 estudiantes de Educación Secundaria Obligatoria y Bachillerato (M=15.02±1.86). Los resultados evidencian que prevención/salud positiva y diversión/bienestar, son los principales factores motivacionales en la práctica del ejercicio físico. Finalmente, con menor impacto en la motivación se encuentra el reconocimiento social/desafío y urgencias de salud. En conclusión, conocer los motivos que apoyan la práctica regular del ejercicio físico puede ayudar a reducir el sedentarismo. Palabras clave: motivación, ejercicio físico, adolescentes, AMPEF. AbstractThis paper aims to identify the motivations that lead adolescents to increase the practice of physical exercise. To do this, applied the questionnaire of Autionforme's reasons for the practice of physical exercise (AMPEF) 342 students of compulsory secondary education (M = 15. 02±1. 86). The results show that positive prevention/health and fun/welfare, are the main motivational factors in the practice of physical exercise. Finally, with less impact on motivation social recognition is / challenge and health emergency. In conclusion, ascertain the reasons which support the regular practice of physical exercise can help to reduce physical inactivity.

“…This approach has been studied extensively in patients with scar-related VT and has shown improved long-term prognosis. [42][43][44] Due to the probabilistic nature of substrate modification, it is accepted that a large amount of ablation will be required. In fact, some centres have suggested a more extensive endocardial and epicardial scar ablation strategy in patients with IHD, termed scar homogenisation.…”

Scar-related reentrant ventricular tachycardia (VT) may be present in a variety of structural heart disease (SHD) phenotypes. In this setting, VT circuits are comprised of viable myocytes separated by fibrosis, allowing for the slow conduction needed to facilitate reentry.1,2 Aetiologies of fibrosis include ischaemic heart disease (IHD), inflammatory conditions, infiltrative cardiomyopathy, dilated cardiomyopathy (DCM), hypertrophic cardiomyopathy and arrhythmogenic right ventricular (RV) dysplasia.Implantable cardioverter defibrillators (ICDs) are the mainstay of therapy for the prevention of sudden cardiac death in patients with SHD.3 However, ICD shocks are associated with diminished quality of life and increased mortality.4-6 Anti-arrhythmic drugs (AADs) have an important role in shock reduction; however these agents often have limited efficacy and significant side-effects. 7,8 Catheter ablation has assumed an increasingly important role in the management of VT. In patients with IHD and drug-refractory VT, ablation has been shown to reduce arrhythmia recurrence and ICD therapies. 9-11Patients who have VT rendered non-inducible by an ablation procedure have a lower VT recurrence rate and mortality compared with those who still have inducible arrhythmias after the ablation.12 Catheter ablation has also been shown to be effective in the treatment of VT storm in patients with SHD receiving chronic AAD therapy. 13In the setting of non-ischaemic SHD, catheter ablation outcome varies according to the nature of the underlying heart disease, with a greater need for epicardial mapping and ablation, higher recurrence rate and more AAD use in long-term follow-up.14-16 For the most part, VT ablation remains underutilised and some patients may benefit from earlier intervention. 17Although ablation also has an important role in the management of patients with idiopathic VT, this review will focus on ablation of scarrelated reentrant VT, the most common mechanism of monomorphic VT in patients with SHD. Pre-procedural PlanningHeart failure optimisation is important for decreasing the risk of Electrocardiographic CharacterisationTwelve-lead electrocardiograms (ECGs) of all clinical VTs are important in localising VT exit sites, identifying potential ablation targets and directing the best ablation strategy including possible epicardial access.In the setting of non-ischaemic IHD, morphological criteria suggesting Abstract Scar-related reentry is the most common mechanism of monomorphic ventricular tachycardia (VT) in patients with structural heart disease. Catheter ablation has assumed an increasingly important role in the management of VT in this setting, and has been shown to reduce VT recurrence and implantable cardioverter defibrillator (ICD) shocks. The approach to mapping and ablation will depend on the underlying heart disease etiology, VT inducibility and haemodynamic stability. This review explores pre-procedural planning, approach to ablation of both mappable and unmappable VT, and post-procedural testing. Future de...

“…The target of the ablation was putative channels and exits within the low-voltage area as identified from a paced QRS morphology similar to the QRS morphology of VT, fractionated potentials, or isolated late potentials during sinus or paced rhythm [11][12][13][14][15][16]. As for the patients included in the later part of the study period, RF energy was applied targeting all delayed potentials toward dechanneling [17]. Furthermore, when target sites were adjacent to the electrical barriers or a region of electrically unexcitable scar, the ablation lesions were extended to the unexcitable area [18,19].…”

a b s t r a c tBackground: Catheter ablation of ventricular tachycardia (VT) is feasible. However, the long-term outcomes for different underlying diseases have not been well defined. Methods: Eighty-eight consecutive patients who underwent catheter ablation of VT using a threedimensional mapping system were analyzed. The primary endpoint was any VT or ventricular fibrillation (VF) recurrence. Secondary endpoints were a composite of death or any VT/VF recurrence. Underlying heart diseases were remote myocardial infarction (remote MI) in 51 patients and non-ischemic cardiomyopathy in 37 (arrhythmogenic right ventricular cardiomyopathy [ARVC] in 18 patients, and dilated cardiomyopathy [NIDCM] in 19). Results: Acute success was achieved in 82 of 88 (93%) patients. During a follow-up period of 39.2 74.6 months, VT recurred in 26 of 87 (30%), and VT/VF recurrence or death occurred in 39 of 87 (45%) patients. ARVC had better outcomes than NIDCM for the primary (p o 0.05) and secondary endpoints (po 0.05). Remote MI-VT revealed a midrange outcome. Conclusions: The long-term outcomes after catheter ablation of VT varied according to the underlying heart disease. ARVC-VT ablation was associated with better long-term prognosis than NIDCM. Remote MI-VT demonstrated a midrange outcome.
