What is one of the signs of wet beriberi?

One of the signs of wet beriberi is a rapid heart rate, which is a key cardiovascular manifestation of thiamine (vitamin B1) deficiency. Wet beriberi specifically affects the cardiovascular system and can lead to an increase in heart rate as the body struggles to maintain adequate circulation and oxygenation due to the effects of inadequate thiamine on cardiac function. Additionally, this condition often involves fluid retention and edema due to heart failure, which further emphasizes the importance of monitoring heart rate and overall cardiovascular health in affected individuals. Other symptoms associated with wet beriberi may include swelling in the legs and a general feeling of weakness, but the rapid heart rate serves as a notable sign reflecting the condition's impact on the heart.
