Common symptoms include: * dyspnea (shortness of breath) Signs include: * tachycardia (a heart rate exceeding the normal resting rate) * continuous "machine-like" (also described as "rolling-thunder" and "to-and-fro") heart murmur (usually from aorta to pulmonary artery, with higher flow during systole and lower flow during diastole) * cardiomegaly (enlarged heart, reflecting ventricular dilation and volume overload) * left subclavicular thrill * bounding pulse * widened pulse pressure * increased cardiac output * increased systolic pressure * poor growth * differential cyanosis, i.e. cyanosis of the lower extremities but not of the upper body. People with<unk>  typically present in good health, with normal respirations and heart rate. If the<unk>  is moderate or large, widened pulse pressure and bounding peripheral pulses are frequently present, reflecting increased left ventricular stroke volume and diastolic run-off of blood into the (initially lower-resistance) pulmonary vascular bed. Eisenmenger physiology is pulmonary hypertension due to a left-to-right shunt. Prominent suprasternal and carotid pulsations may be noted secondary to increased left ventricular stroke volume.
