Not to be confused with Beck's cognitive triad. The rising central venous pressure is evidenced by distended jugular veins while in a non- supine position. In severe hypovolemia triava, the neck veins may not be distended.
Heart murmur Systolic heart murmur: This is in accordance with the Frank-Starling law of the heartwhich explains that as the ventricles fill with larger volumes of blood, they stretch further, and their contractile force increases, thus causing a related increase in systolic blood pressure.
