Blood poisoning can lead to a faster-than-normal heart rate at rest, a condition called tachycardia. This happens as the body works harder to circulate oxygen and fight the infection, which may feel like a racing or pounding heart. In a healthy individual, the heart rate at rest is usually between 60 and 100 beats per minute, but tachycardia causes it to exceed this range. Persistent tachycardia can signal that the infection is impacting cardiovascular function, highlighting the body’s effort to manage the strain caused by the underlying condition.
