The peak of the R wave is said to occur at about the same time as the beginning of systole.
For each beat of the heart, when does the peak of blood flow in the fingertips occur relative to the peak of the R wave?
Homework Answers
For each beat of the heart, the peak of blood flow in the fingertips that occurs relative to the peak of the R wave is the R- pulse interval.The R-pulse interval corresponds to the interval between the peak of the R wave and the beginning of the peak of the pulse wave that is know to follow the R wave. It also corresponds to the amount of time that the blood takes to be ejected from the heart and then arrive at the fingertip.For every person, it is different.

1. Is the time interval between the R wave and the peak of the pulse wave the same for each subject? Does this time interval differ with heart rate? 2. Do you see any differences in the size or shape of dichrotic notches from different subjects? Remember: the tension on the plethysmograph strap affects the shape of the pulse recording. 3. Is the time interval between the peak of the pulse wave and the bottom of the dichrotic notch the...

The heart rate (HR) is expressed in beats per minute and is calculated from the average beat period (R-R) by using the following equation: 60 sec/min HR (b/min) - - R-R 7. Scroll through the recording and find the section of data immediately after exercise. Repeat Steps 2 through 6 for this section of data. 8. Move to the sections of data at 1 minute after exercise Repeat Steps...

a. A 1V peak to peak sine wave with a frequency of 1 kHz is applied across a 5 kΩ resistor. Find an expression for the current through the resistor as a function of time. b. The same input voltage is applied across a single 2 µF capacitor, what is the current through the capacitor as a function of time? c. The frequency of the sine wave is now increased to 5 kHz. How does this affect the current in...

AAAAA Label P. QRS, and Twaves on the ECG strip in Figure 4.5. Figure 1.5: ECG strip. DETERMINE HEART RATE FROM AN ECG The range of normal heart rates is called normal sinus rhythm (NSR). In an average adult NSR is between 60 and 100 bpm. A heart rate below 60 bpm is called bradycardia. However, a highly acro bically conditioned persons often have a normal heart rate below 60 bpm. A heart rate above 100 bpm in an adult...

How does the density of wildebeests grazing on Panicum grasses change over time after the peak rain? a. Wildebeest density is relatively constant throughout the six months following the rain. b. Wildebeest density reaches its maximum one month after the rain but then decreases to nearly zero about three months after the rain. Six months after the rain, however, the density has increased slightly. c. Wildebeest density is very low for two months after the rain but then begins to...

You are studying the heart of a strange newly-discovered primate
species. Its basic structure is like that of the human heart, but
the timing of the wave of excitation which emanates from the
SA-node and spreads throughout the atria and ventricles are quite
different. The figure below shows the time of arrival of the wave
at various points in the heart relative to its generation at the
SA-node.

In hemodynamics, blood flow through the cardiovascular system
can be modeled as an electric circuit in which the blood serves as
electricity, the blood vessels as resistive wires, and the heart as
a battery (see Figure 1).

Opening Case Lennox looked anxious and happy at the same time. He was happy because he was just a week away from going on a well-deserved vacation that he and his wife had been planning for some time. He was anxious however because it was the first time in a long time that he would be leaving his business for about a month and was concerned about how the operations would go without him present. Lennox is the proprietor of...
