Dicrotic notch ekg
WebAs ventricular pressure drops, there is a tendency for blood to flow back into the atria from the major arteries, producing the dicrotic notch in the ECG and closing the two semilunar valves. The second heart … WebThe sudden closing of the aortic valve produces a pressure wave as the blood pushes against it, resulting in the observed spike in aortic pressure. This spike is called the dicrotic notch. Another interesting feature of the figure is the EKG tracing that is …
