Have you ever passed out? Tell the doctor about fainting attacks

Anyone who has ever passed out should definitely tell their doctor. Because a brief loss of consciousness can indicate an increased risk of sudden cardiac death. The German Heart Foundation points this out.

Sudden cardiac death sometimes comes with warning

Most of the time there is a sudden cardiac death (or second death or "second heart death") without warning. But in some patients the event announces itself. For example, chest pain, palpitations, shortness of breath or dizziness can indicate imminent death. Such symptoms can appear a few hours before the event, sometimes days to weeks beforehand. Even a brief loss of consciousness can indicate an increased risk of sudden cardiac death. The German Heart Foundation points this out on its website.

Clarify fainting attacks conscientiously

Fainting attacks should therefore always be carefully examined by a doctor.

As far as the doctor is concerned, it should definitely be mentioned whether, for example, shortly before the person passed out, there was evidence of cardiac arrhythmia such as palpitations, palpitations, rapid heartbeat, or a significantly slower pulse than usual.

Fainting attacks, which are due to heart diseases such as rhythm disturbances, often mean a greatly increased risk of sudden cardiac death.

Did you lose consciousness while exercising?

Another important indication of heart-related loss of consciousness are fainting attacks that occur during physical exertion, such as climbing stairs, running uphill or doing sports.

If this was the case, it should be absolutely ensured that this circumstance does not go away under any circumstances when talking to the doctor.

It has long been known that sudden cardiac death is more common in athletes than in non-athletes. Sudden cardiac death in sports is known even in children.

Prevent unconsciousness with a simple movement

It is also important to state whether the fainting has suddenly occurred out of nowhere or whether harbingers have been perceived such as nausea, sweating, dizziness, drowsiness, weakness, discomfort or blurred vision.

Because in the case of fainting forms that are slowly announcing themselves with harbingers, your doctor can show you a simple operation with which you can often easily prevent an impending fainting attack in the future, writes the Heart Foundation.

Also give unpleasant information

In some cases, the situation where the loss of consciousness occurred may be embarrassing or otherwise uncomfortable, such as when the fainting attack occurred during a violent argument, urination, sexual activity, spider sight, or an enthusiastic fan at a pop concert .

But even in such cases, the situation should absolutely be reproduced correctly, since this gives important information about the respective cause and otherwise there is a risk that an incorrect diagnosis will be made.

Do you take any medicine?

If you are taking medication, you should make a compilation of which active ingredients and in what dosage you took in the days before fainting.

This can be particularly important, for example, in the case of loss of consciousness that occurred when you got up from lying or sitting, since in such cases blood pressure medications that are too strong often play a role.

The doctor will not only look at the dosages of the blood pressure medication, but also pay attention to active substances that tend to interact with blood pressure medication and may have increased their effect.

For this reason, you should make a note of all medications, including any medications that you may have obtained in the pharmacy without a prescription. (ad)
