The signs are low arterial blood pressure, distended neck veins, and distant, muffled heart sounds.

[5] The first formulation of the law was theorized by the Italian physiologist Dario Maestrini ...
Cardiology. Pulsus alternans is a physical finding with arterial pulse waveform showing alternating strong and weak beats.

[1] [2] This symptom consists in rhythmic nodding or bobbing of the head in synchrony with the beating of the heart, in general as a result of aortic regurgitation whereby blood from the aorta regurgitates into the left ventricle due to a defect in the aortic valve. [3] [4] The nodding is an indication ...
