- Given the following information, calculate cardiac output: R-R interval = 0.6 second, EDV = 160 mL, ESV = 30 mL * 7.0 L/min 10.0 L/min O 13.0 L/min O 15.0 L/min200 Curve 1 175 Curve 2 150 125 Curve 3 100 75 50 25 50 100 150 200 250 300 350 400 LV End Diastolic Volume (mL) Use the information in this paragraph and the image above to answer the question below. This figure shows the relationship between EDV and SV. Curve 2 is representatíve of a normal individual sitting on a bike, resting. There are two other curves illustrated and there are multiple points landmarked with a "o" and the letters "A to F". You can assume that the only changes in relevant variables are described in each question. If a variable is not mentioned you can assume that it has not changed. The starting point is "A". Select an appropriate pointif there was an increase in cardiac inotropy. 23 D. Stroke Volume (mL)a cardiac ultrasound patient is found to have a left ventricle stroke output of 98mL and a resting heart rate of 65bpm, what is the patients cardiac output?
- Calculate %HRR for an individual (63 years old) who has a heart rate of 140 during running. The resting heart rate of this individual is 60 (HRmax= 208-0.7* age).Given heart rate = 72 bpm, stroke volume = 70 mL, calculate cardiac output.if a patient with the P-V loop below had a heart rate of 50 BPM, their cardiac output would be approximately 6.25 L/min 125 ml/min 625 L/min 8.75 L/min
- Component Amplitude(mV) Duration (s) P wave 0.046 0.07 QRS complex 0.839 0.08 T wave 0.061 0.2 Describe the physiological events in the heart muscle represented by each ECG component (the P wave, the QRS complex, and T wave). Why does the QRS complex have the largest amplitude?0.2 0.4 0.6 0.8 In the ECG above, which portion of the graph corresponds to the electrical activity of the heart when the ventricles are contracting? QRS R PQRI need to calculate the approximate heart rate based on the given ECG results, but I can't get how to determine the length of time between two consecutive R waves. What I see, it's one second between the two highest waves (I suppose they are R waves). But it means the heart rate should be 60 beats per minute, but there is no option for this answer. Teach me how to determine correctly the length of time between two consecutive R waves.
- The cardiac output of 70-year-old man at rest is 5.5L / min; mean HR is 85 bpm. Left ventricular end-diastolic volume (LVEDV) is estimated to average 85 ml. What is the mean ejection fraction?Unlike the discrete waveform from an electrocardiogram, the electromyogram waveform is irregular. Why do you suppose this is?If end-diastolic volume (EDV) is 200 ml, and end-systolic volume (ESV) is 50 ml, calculate stroke volume (SV) and ejection fraction (EF)
