“…Epicardial ablation is an effective tool for the treatment of complex arrhythmias such as postmyocardial infarction ventricular tachycardia (VT). In such procedures, care must be taken to avoid energy delivery proximal to coronary vasculature which can lead to vessel occlusion and thrombus formation [49,50]. In this ex vivo experiment, we showcase the capability of the proposed system to detect the blood blow, which could potentially be used for real-time monitoring for the ablation.…”

Here we present a novel phase-sensitive swept-source optical coherence tomography (PhS-SS-OCT) system. The simultaneously recorded calibration signal, which is commonly used in SS-OCT to stabilize the phase, is randomly sub-sampled during the acquisition, and it is later reconstructed based on the Compressed Sensing (CS) theory. We first mathematically investigated the method, and verified it through computer simulations. We then conducted a vibrational frequency test and a flow velocity measurement in phantoms to demonstrate the system's capability of handling phase-sensitive tasks. The proposed scheme shows excellent phase stability with greatly discounted data bandwidth compared with conventional procedures. We further showcased the usefulness of the system in biological samples by detecting the blood flow in ex vivo swine left marginal artery. The proposed system is compatible with most of the existing SS-OCT systems and could be a preferred solution for future high-speed phase-sensitive applications.

“…Debido a su naturaleza asintomática, benigna y auto limitada, suele ser detectada de forma incidental en monitorizaciones electrocardiográficas de rutina, pre y post quirúrgico, su manejo es expectante, a menos que se constate la presencia de inestabilidad hemodinámica asociada, debido a su similitud con otras anomalías, es importante tratar la causa de origen antes del uso de anti arrítmicos por riesgo de deterioro precipitado, siendo resuelta una vez que la frecuencia sinusal supere los focos ventriculares (Hagel et al, 2017;Whitaker et al, 2015).…”

El RIVA se considera la arritmia de mayor prevalencia durante la fase de resolución del infarto agudo de miocardio. la infraestimación del riesgo real sobre ciertas causas adyacentes podría condicionar el desarrollo de complicaciones, siendo determinante la identificación de cambios electrocardiográficas. Determinar los diferentes contextos clínicos que orientan hacia el ritmo idioventricular y su diferenciación de la taquicardia ventricular, así como de otras alteraciones análogas. Con base en criterios de inclusión y exclusión se ejecutó un análisis de caso clínico, junto al análisis de bibliografía de alto impacto. Paciente de 74 años de edad acude a evaluación cardiovascular posterior a IAM, hemodinámicamente estable; se realizó electrocardiograma encontrándose un RIVA más salvas de fibrilación auricular. En conclusión, el manejo especifico se reserva en casos de inestabilidad hemodinámica, asimismo se deberá hacer énfasis en la prevención y control de factores de riesgo cardiovascular.
