Phase contrast velocity encoded MRI allows one to obtain measures of blood velocity plotted over the cardiac cycle through the valves and the great vessels.
The newest and most advanced testing uses a Hemathix SCV-200 automated scanning capillary tube viscometer (formerly known as the Rheolog), which is capable of measuring viscosity over the complete range of physiologic values experienced in a cardiac cycle (10,000 shear rates) with a single continuous measurement.
Data were analyzed over five consecutive cardiac cycles for each embryo, and heart rate (beats per min) was determined from the interval of cardiac cycles.
The system, which is synchronized to the individual patient's cardiac cycle, inflates the cuffs with air to create external pressure when the heart is resting and deflates the cuffs just before the next heartbeat.
If a ball hits a student in the right spot at the right time in the cardiac cycle, sudden cardiac arrest may follow.
It is largely the result of the exquisite timing of the blow during a narrow window within the repolarization phase of the cardiac cycle, 15 to 30 milliseconds prior to the peak of what is called the heart's T-wave.
Blood pressure varies constantly within the cardiac cycle of contraction and relaxation of the heart and is also affected by the level of physical exertion, anxiety, stress, emotion and other factors.
