Provided below are the pressures in the left atrium, left ventricle, and aorta at a given point during the cardiac cycle of three different NORMAL patients. Based on the three pressures, what phase of the cardiac cycle is patient 1 in? Based on the three pressures, what phase of the cardiac cycle is patient 2 in? What phase of the cardiac cycle is patient 3 in?
\( \underline{\text { Patient } 1} \) Atrial pressure: \( 15 \mathrm{mmHg} \) Ventricular pressure: \( 10 \mathrm{mmHg} \) Aortic pressure: \( 90 \mathrm{mmHg} \) Patient 2 Atrial pressure: \( 10 \mathrm{mmHg} \) Ventricular pressure: \( 90 \mathrm{mmHg} \) Aortic pressure: \( 118 \mathrm{mmHg} \) Patient 3 Atrial pressure: \( 12 \mathrm{mmHg} \) Ventricular Pressure \( 95 \mathrm{mmHg} \) Aortic pressure: \( 80 \mathrm{mmHg} \)
[Select] Isovolumetric Contraction Isovolumetric Relaxtion Ejection Filling
Answer: The patient 1 is in the phase of Filling Because the atrial pressure is higher than the ventricular pressure and aortic pressure also not increasing. Here the bicuspid valve is open due to higher left atrial pr
