By cardiacmonitor, heart rhythm is normal, with normal intervals. A normalQRS complex follows each P wave. A 6 second rhythm strip shows 8QRS complexes. An ECG is normal. On echocardiogram, all cardiacchambers and heart valves are normal in appearance. Leftventricular end diastolic volume is 100 ml. Left ventricular endsystolic volume is 40 ml. All calculations and units must beincluded in calculations for full credit.  Calculate heart rate.__________________________  Calculate stroke volume.__________________________  Calculate left ventricular ejectionfraction. __________________________  Calculate cardiac output.__________________________  Calculate mean arterial pressure._______________________
