What is dromotropicity?
Velocity of conduction through the AV node
|
|
If a blood pressure is measured at 160/90, what is the patient’s pulse pressure?
70 mmHg
|
|
An increase in heart rate subsequently increases contractility of the heart, what is this occurrence known as?
Treppe effect

Calculate the vascular resistance of this patient. Renal blood flow = 400 mL/min, Pressure in renal artery = 60 mmHg, Pressure in renal vein = 10 mmHg
0.125 mmHg/mL/min
|
|
HR = 145bpm, End systolic volume = 40 mL, End diastolic volume = 130 mL, Systolic pressure = 130 mmHg, Diastolic pressure 80 mmHg
Calculate patient’s CO? Calculate patient’s SV? Calculate patient’s mean arterial pressure (MAP)?
CO = 13 L/min
SV = 90 mL/beat MAP= 97 mmHg |
