cardiac cycle การใช้

• The duration of the cardiac cycle is the reciprocal of heart rate.
• The mitral annulus changes in shape and size during the cardiac cycle.
• Each cardiac cycle appears as a peak, as seen in the figure.
• :Might want to take a look at our Cardiac cycle page.
• "' Systole "'is the part of the cardiac cycle when the ventricles contract.
• With a sinus rhythm, the mitral annulus undergoes dynamic changes during the cardiac cycle.
• The area under the flow-versus-time curve for one cardiac cycle is the stroke volume.
• The device also measures the variation in pressure that occurs with the cardiac cycle.
• The pressure in arteries varies during the cardiac cycle.
• It can run at a constant speed, or two variable speeds during the cardiac cycle.
• This short-lasting portion of the cardiac cycle takes place whilst all heart valves are closed.
• Throughout the cardiac cycle, blood pressure increases and decreases.
• The first 2.5 seconds show a normal cardiac cycle.
• The venous hum is heard throughout the cardiac cycle.
• The article Cardiac cycle discusses the normal heartbeat.
• The cardiac cycle refers to a complete heartbeat which includes systole and diastole and the intervening pause.
• There is no external resistance to blood flow and blood flow is continuous throughout the cardiac cycle.
• At the beginning of the cardiac cycle, in early diastole, both the atria and ventricles are relaxed.
• The "'cardiac cycle "'refers to the sequence of mechanical and electrical events that repeats with every heartbeat.
• In contrast to defibrillation, synchronized electrical cardioversion is an electrical shock delivered in synchrony to the cardiac cycle.
