Cardiovascular Emergencies: Cardiac Arrhythmias
Emergency Room · Clinical Specialties
How it begins
La comprensión del origen, la propagación y la interrupción de las arritmias cardiacas en el servicio de urgencias requiere un análisis riguroso de la fisiología celular miocárdica. El miocardio está constituido por dos tipos de poblaciones celulares funcionalmente distintas: las células de respuesta rápida (miocardio de trabajo auricular y ventricular, así como el sistema de Purkinje) y las células de respuesta…
