Palpitations: When Colds Trigger Heart Issues

Common cold

When I was 20 years old, due to my job, I was drinking almost a cup of coffee every day, sometimes even two or three cups.
One night, I suddenly experienced a rapid heartbeat while trying to sleep, which made it impossible for me to rest.
After tossing and turning all night, I was fine the next evening.
However, ever since then, whenever I catch a cold, I experience a fast heartbeat at night, regardless of whether I take cold medicine.
Recently, while I had a cold, I have been experiencing a rapid heartbeat every night when trying to sleep, along with some tightness and slight shortness of breath.
During the day, I don’t feel any symptoms, but I do notice a bit of anemia and low blood pressure.
Could this be considered palpitations? If so, how serious is it? If it is serious, which specialty should I consult?

Dear Natasha, this is what is known as palpitations.
Some stimulants, such as caffeine and cold medications, can trigger this.
I recommend that you visit a cardiology clinic for further evaluation.
Thanks.

More Info

Palpitations, or the sensation of feeling your heart beating rapidly or irregularly, can be concerning, especially when they occur frequently or in conjunction with other symptoms like shortness of breath or chest tightness. Your experience of having palpitations primarily at night, especially when you have a cold, is not uncommon. There are several factors that could contribute to this phenomenon.

Firstly, it is important to understand that colds and other upper respiratory infections can lead to increased sympathetic nervous system activity. This can cause your heart rate to increase, leading to palpitations. Additionally, when you are sick, your body is under stress, which can also trigger these sensations. The presence of fever, even mild, can elevate your heart rate as your body works to fight off the infection.

The caffeine consumption you mentioned during your younger years could also play a role. Caffeine is a known stimulant that can increase heart rate and potentially lead to palpitations, especially if consumed in large quantities or if you are sensitive to its effects. If you have since reduced your caffeine intake, your body may have adjusted, but any residual sensitivity could still trigger palpitations during times of illness.

Regarding your symptoms of feeling a bit anemic and having low blood pressure, these factors can also contribute to palpitations. Anemia can reduce the oxygen-carrying capacity of your blood, which may lead to your heart working harder to supply oxygen to your body, especially during times of stress or illness. Low blood pressure can cause dizziness and a feeling of lightheadedness, which may accompany palpitations.

In terms of whether your symptoms constitute a serious condition, it is essential to consider the context. Occasional palpitations, especially when associated with a cold and not accompanied by severe symptoms like chest pain, fainting, or prolonged episodes, are often benign. However, if you find that your palpitations are frequent, persistent, or accompanied by concerning symptoms, it would be wise to consult a healthcare professional.

You should consider seeing a cardiologist, especially if your symptoms continue or worsen. A cardiologist can perform tests such as an electrocardiogram (ECG) or a Holter monitor to assess your heart's rhythm and determine if there are any underlying issues that need to be addressed. Additionally, if you are experiencing significant anxiety related to your symptoms, discussing this with a healthcare provider may also be beneficial, as anxiety can exacerbate palpitations.

In conclusion, while your experience of palpitations during colds may not be uncommon, it is essential to monitor your symptoms closely. If they persist or are accompanied by other concerning signs, seeking medical advice is the best course of action. Your health and peace of mind are paramount, and a healthcare professional can provide the necessary guidance and reassurance.
