Why Does Pda Cause Bounding Pulse?
Because Blood Runs out of the Aorta into the Pulmonary Artery Between Heart Beats, the Patient's Diastolic Blood Pressure Will Be Somewhat Lower Than Usual...
Because blood runs out of the aorta into the pulmonary artery between heart beats, the patient's diastolic blood pressure will be somewhat lower than usual. This makes their pulses feel “bounding” (very strong and forceful).
Why is there LVH in PDA?
Increased flow returning to the left heart results in increased left atrial and left ventricular end-diastolic pressures. The left ventricle compensates by increasing stroke volume and eventually may hypertrophy to normalize wall stress.
How does PDA cause cyanosis?
The reason for the differential cyanosis and clubbing is that due to the right-to-left shunt across the PDA, deoxygenated blood from the right ventricle is preferentially directed into the aorta distal to the left subclavian artery and into the lower extremities.
