During their exercise test you notice the following rhythm. Please identify the rhythm. O Normal Sinus Rhythm with PACs 23 mmke: 10 mmmy BWF OF MAF On H 40H2 Of

Define the term pacemaker potential (=drifting potential) and be able to identify it when given a graph of an action potential in an autorhythmic cell such as the one below. -40 EL T -60 0 sec - ^^ 0.8 sec = 800 msec Time daRbCoDdEe AaBbCcD ABNC ADVE Emphasis Heading 1 I Normal 1.6 sec -1600 msec

4.4. On the circulatory system, what are the correct statements? PHYSIOLOGY_advanced  (OJO) Pacemaker cells of the heart are neurons with a stable resting membrane potential. Pacemaker cells of the sinus node, located at the left atrium, determine the heart beat frequency. Cardiac output is a function of the heart beat frequency and the stroke volume. The Frank-Starling mechanism allows coupling of the venous return with the stroke volume. Within each capillary bed there is a net loss of liquid to the extracellular space; this imbalance depends on the hydrostatic pressure and the colloid osmotic pressure gradients.

O Cardio_Phys 6 Unanswered Which of the following channels are involved in the action potential in contractile cells of the heart? A Na+ leak channels voltage-gated Na+ channels C voltage-gated Ca+2 channels D all of the above E B and C only

( explain well all point of question with step by step answer. )

I need help with a respiratory question, thank you, I really appreciate it Stroke volume can be calculated using which formula?   Group of answer choices   End-diastolic volume – end-systolic volume Ejection fraction × heart rate Ejection fraction × end-systolic volume Cardiac output ÷ end-diastolic volume
