(a) it is possible to measure a patient’s heart rate by either palpating their peripheral pulse, by observing their ecg, or by listening for the lub-dup through a stethoscope. however, patients with atherosclerosis of the femoral artery may not have a pulse in the popliteal artery or dorsalis pedis of the foot. does this mean that they will also lack a heart beat (lub-dup) or qrs complex? explain the relationship between a heart beat, pulse, and qrs complex. (b) why is there a delay between systole of the ecg and the resulting pulse felt in the finger (r-pulse)?
