Will your heart rate speed up if you have a cold?

During a cold, patients will always have many symptoms, and these symptoms will always cause a lot of discomfort to the patient's body. After a cold occurs in the human body, the patient should find the correct method for treatment. Otherwise, if the cold develops into a serious cold, it will be too late to treat it. However, some cold patients find that their heart rate increases significantly during the cold. Is this a normal phenomenon?

(1) During colds and fevers, blood flow increases, heart rate accelerates, and oxygen consumption increases, which may lead to arrhythmias in patients with unstable cardiac function and low reserve capacity.

(2) Although blood volume does not change significantly when exposed to cold or hot temperatures, red blood cells flow from their storage sites into the blood, increasing red blood cell volume and hematocrit, leading to increased blood viscosity and increased cardiac workload, causing arrhythmias.

(3) When you have a cold or fever, it directly affects your heart function. When you have a cold or fever, your body's arterial oxygen saturation decreases, and the heart functions in a relatively hypoxic environment, which can easily induce arrhythmia.

(4) Direct effects of infection toxins: bacteria damage the heart or toxins released by heart bacteria damage each heart valve, pericardium, myocardial nerves and coronary arteries. Neurotoxins such as diphtheria can damage nerves in the heart and brain, nerves. These neurotoxins can affect the rhythm, conduction and repolarization of the heart, leading to the occurrence of arrhythmias.

(5) Viral myocarditis: the virus directly invades the cardiac conduction system and can cause arrhythmias.

It is recommended that everyone pay attention to developing good habits in daily life and always maintain a positive attitude. If you find that your body is malfunctioning, you must seek medical attention immediately. If you have a cold, you will find that your heart beats faster. This may be caused by a minor illness and the body's full recovery. Don't panic too much. This is a normal symptom of a cold. You just need to treat the cold well. After the cold is cured, exercise more, pay attention to diet and rest, have a strong physique, and enhance immunity.
