A middle-aged patient presents for her annual physical examination inseemingly good health. She has a blood pressure of 128/83 mm Hg, andechocardiography indicates that end-diastolic volume is 140 mL and end-systolic volume is 80 mL. A routine ECG is obtained and is shown below.The ECG reveals the patient is in normal sinus rhythm with an R-R intervalof 0.76 seconds. This corresponds to a heart rate of:70 beats/min74 beats/min79 beats/min84 beats/min88 beats/min

The ECG ( Electrocardiogram) is a diagnostic test. This test helps to determine the electrical…

Trace the journey of a drop of blood starting from the right atrium, continuing to the right thumb, and returning to the right atrium. This would include a trip through the heart. Be sure to identify both the arterial and venous vessels as well as all of the relevant structures within the heart. Considering the online nature of this exam, drawings are not required. Simply type in the order of structures with a dash (-) between structures.
A 65 years old male patient with history of heart disease came to his doctor’s office for annual physical exam. On examination, his pulse was 78/minute, respiration 18/minute, temperature was 95.30F. His blood pressure was recorded as 170/93mm Hg. Further tests revealed the patient’s stroke volume as 65 ml/beat and ESV as 80 ml. From this short history answer/calculate the following: Cardiac output: EDV: Ejection fraction:

You have been asked to take a pulse and a blood pressure reading on 80-year-old Mrs. Leonard, who is very frail and thin. The provider is running ahead of schedule and is waiting on you so he can examine the patient. You have to work rather quickly. You take the patient's pulse rate, which is 96 beats per minute. You notice that the patient's heart appears to skip a few beats. The patient's blood pressure is 152/94. A. What type of blood pressure cuff would work best on this patient? B. What may be a contributor to the patient's pulse rate being so high? C. Would the patient be considered to have controlled blood pressure? D. The patient's heart rhythm would be termed as what?
