Cardiac arrhythmias

Heart rate is a measurement of how many times your heart beats per minute. It is a simple way to monitor the health of your heart and is affected by a variety of circumstances, including vitamin B1 deficiency. In fact, thiamine shortage frequently causes a slower heart rate than normal. In research with thiamine-deficient rats, there was a significant drop in heart rate. Cardiac arrhythmias caused by thiamine shortage can lead to weariness, dizziness, and an increased risk of fainting.

Thiamine participates in the metabolism of carbohydrates, lipids, amino acids, glucose, and alcohol, and it is especially crucial in the function of central and peripheral neurons, as well as heart muscle. Degeneration of the peripheral nerves, thalamus, corpus callosum, and cerebellum is caused by thiamine deficiency. Cerebral blood flow is greatly reduced, whereas vascular resistance rises. Vasodilation, tachycardia, broad pulse pressure, sweating, heated skin, and lactic acidosis are the chief consequences. Heart failure ensues, resulting in dyspnea, pulmonary edema, and peripheral edema. Vasodilation may persist, potentially resulting in shock.
