    The heart's electrical activity can be recorded using small electrodes placed on the skin. This test is called an electrocardiogram (ECG)<\/strong>. Like a fingerprint, every person's ECG is unique. It records the heart's electrical activity, heartbeat by heartbeat.<\/p>

    Any disturbance in the heart's normal electrical conduction will produce changes on the ECG. Heart rhythm disorders, conduction blocks, a heart attack<\/strong>, or thickening or enlargement of the heart muscle can all produce characteristic ECG abnormalities.<\/p>

    No. The heart is located almost in the center of the chest, between the two lungs, in an area called the mediastinum<\/strong>. About two-thirds of its mass lies to the left of the body's midline, which is why many people think it is located entirely on the left side.<\/p>

    This orientation is related to its position within the chest and the arrangement of the major blood vessels connected to it. The apex<\/strong> (the tip of the heart) points downward, forward, and to the left.<\/p>

    Yes. The heart is enclosed by a membrane called the pericardium<\/strong>. It protects the heart, keeps it in place, and allows it to move freely with each heartbeat thanks to a small amount of lubricating fluid.<\/p>

    The sounds of the heart do not come from the heart muscle itself. They are produced mainly by the closing of the heart valves. Using a stethoscope, a healthcare professional can listen to these characteristic heart sounds.<\/p>

    A heart murmur is an extra sound heard by a healthcare professional while listening to the heart with a stethoscope. It is caused by turbulent blood flow within the heart or the major blood vessels. A heart murmur is not a disease in itself. It may be completely normal (an innocent murmur<\/strong>) or be associated with a heart condition, such as a narrowed or leaking heart valve.<\/p>

    Yes. When you lie on your side, your ear is pressed against the pillow. This pressure makes it easier to perceive the pulsations of the small arteries around the ear. Because these pulsations are synchronized with your heartbeat, they can create the impression that you are hearing your heart beating.<\/p>

    In most cases, this is a completely normal phenomenon that disappears when you change position. This sound does not mean that your heart is beating too hard or that it is unhealthy.<\/strong><\/p>

    At rest, a normal adult heart rate is generally between 60 and 100 beats per minute<\/strong>. It varies depending on age, physical fitness, emotions, medications, and overall health. In people who are in excellent physical condition, especially athletes, a resting heart rate below 60 beats per minute can be completely normal.<\/p>

    It is normal for the heart to beat faster during physical activity, emotional situations, periods of stress, or after consuming caffeine or other stimulants. This increase in heart rate helps meet the body's increased demands. However, if your heart beats rapidly for no apparent reason, persists for a prolonged period, or is accompanied by symptoms such as dizziness or discomfort, you should consult a healthcare professional.<\/p>

    A heart valve is a structure that acts like a one-way door. It opens to allow blood to flow from one chamber to another or into an artery, then closes to prevent blood from flowing backward. The heart has four valves that work in perfect coordination with each heartbeat.<\/p>

    The heart pumps blood throughout the body, but it also needs a constant supply of oxygen and nutrients. This supply is provided by the coronary arteries<\/strong>, which nourish the heart muscle. If one of these arteries becomes narrowed or blocked, part of the heart muscle may be deprived of oxygen, leading to a heart attack<\/strong>.<\/p>

    The heart is the first organ to become functional during a baby's development. It begins beating about 22 days after fertilization<\/strong>, when the embryo is only a few millimeters long.

    No. Chest pain can have many different causes<\/strong>. It may come from the muscles or ribs, the lungs, the esophagus or stomach, and can sometimes be associated with stress or anxiety.<\/p>

    However, some chest pain can be caused by a heart problem, particularly when the heart muscle does not receive enough blood and oxygen.<\/p>

    The way the pain feels, the circumstances in which it occurs, and the symptoms that accompany it can help determine its cause.<\/strong><\/p>

    Not necessarily. The location of the pain alone cannot determine its cause or severity.<\/strong><\/p>

    Pain originating from the heart may be felt in the center of the chest, on the left side, in the back, in the shoulders, or more diffusely. Conversely, pain located on the left side can have many other causes, including muscle or digestive problems.<\/p>

    The location of the pain is therefore only one of several factors considered during a medical evaluation.<\/strong><\/p>

    Chest pain that occurs during physical activity should not be ignored<\/strong>, particularly if it is new or repeatedly occurs under similar circumstances.<\/p>

    It is best to stop the activity and rest. Even if the pain goes away, a prompt medical evaluation is recommended to determine its cause.<\/strong><\/p>

    If it persists despite stopping the activity, becomes severe, or is accompanied by significant shortness of breath, sweating, nausea, severe weakness, or loss of consciousness, call 911.<\/strong><\/p>

    Yes. Normal heart tests are reassuring for the situation that was being evaluated at the time they were performed<\/strong>, but they cannot predict what may happen later.<\/p>

    New chest pain should therefore not be dismissed simply because a previous electrocardiogram, stress test, echocardiogram, or other cardiac test was normal.<\/p>

    Shortness of breath is the sensation of not getting enough air or having to make a greater effort to breathe<\/strong>. It can occur normally during intense exercise, but it can also be associated with various health problems.<\/p>

    There are many possible causes. They may be cardiac or pulmonary<\/strong>, but shortness of breath can also be related to anemia, an infection, physical deconditioning, excess weight, or anxiety.<\/p>

    When shortness of breath is new, worsening, or occurs with less and less exertion<\/strong>, it should be evaluated to determine the cause.<\/p>

    Some shortness of breath can be normal during physical activity, particularly when climbing several steps quickly. It depends, among other things, on the intensity of the activity, age, and physical condition.<\/p>

    However, it deserves more attention when it is new, more pronounced than before, or occurs with increasingly less demanding activities<\/strong>.<\/p>

    A change in one\u2019s usual ability to exercise is therefore important to consider and may warrant a medical evaluation.<\/p> <\/div>\n\n <\/div>\n\n <\/div>\n\n <\/div>\n <\/div>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

    Some people have more difficulty breathing when lying down and need to raise their head with several pillows or even sit up to breathe more easily<\/strong>. This symptom is called orthopnea<\/strong>.<\/p>

    It can occur in people with heart failure. When lying down, more blood returns to the heart and lungs. If the heart has difficulty handling this additional volume, fluid can build up in the lungs and make breathing more difficult.<\/p>

    Other conditions can also cause shortness of breath when lying down. A recent onset of this symptom or a worsening of it warrants medical evaluation.<\/strong><\/p>

    Yes. A sudden and unusual sensation of not getting enough air<\/strong>, particularly when it occurs at rest, can be a sign of a serious problem.<\/p>

    A palpitation is the unusual awareness of your own heartbeat<\/strong>. It may feel as though the heart is beating too fast, too forcefully, irregularly, or sometimes seems to \u201cskip a beat.\u201d<\/p>

    Palpitations are common and can occur with a normal heart rhythm as well as with an abnormal rhythm.<\/p>

    It is therefore a sensation that is felt and, by itself, is not a diagnosis.<\/strong><\/p>

    This sensation is often related to an extra beat<\/strong>, also called an extrasystole<\/strong>, which occurs earlier than expected. It is usually followed by a brief pause and then by a beat that may feel stronger.<\/p>

    This sequence can create the impression that the heart stops for a moment, skips a beat, or gives a stronger thump in the chest<\/strong>.<\/p>

    These premature beats are common and often harmless. However, when they are new, very frequent, or accompanied by other symptoms, an evaluation may be necessary.<\/strong><\/p>

    Yes. Stress, caffeine, and alcohol<\/strong> can trigger palpitations in some people. Sensitivity to these factors, however, varies considerably from one person to another.<\/p>

    Lack of sleep, fatigue, dehydration, or certain medications can also make the heartbeat more noticeable.<\/p>

    Palpitations are often intermittent and may have disappeared by the time of the medical consultation. Collecting some information during an episode can therefore be very helpful.<\/strong><\/p>

    You can check your pulse<\/strong> to see whether the heartbeat seems regular or irregular and to measure its rate. A blood pressure monitor can also provide the heart rate in addition to measuring blood pressure.<\/p>

    Read more:<\/strong> The Pulse<\/em><\/span><\/a><\/p>

    Writing down the time, duration, and circumstances<\/strong> in which the episode occurs, as well as any accompanying symptoms, can also help identify the cause.<\/p>

    Finally, if a smartwatch or personal device can record an electrocardiogram (ECG) during the symptoms, saving the recording and showing it to your healthcare professional can help with the diagnosis.<\/strong><\/p>

    Fatigue is a subjective symptom<\/strong>: it is a sensation that cannot be seen and may be experienced very differently from one person to another.<\/p>

    It is very common and can have many causes<\/strong>, including lack of sleep, stress, infection, anemia, certain medications, or reduced physical fitness.<\/p>

    The heart does not generally cause fatigue<\/strong> unless it is weakened. One exception is severe mitral valve stenosis, which can cause fatigue even when the heart muscle maintains normal strength.<\/p>

    These terms describe different sensations, but they are often confused.<\/p>

    Vertigo<\/strong> creates the sensation that the room is spinning around you or that you yourself are spinning. It is most often related to the balance system located in the inner ear.<\/p>

    Dizziness<\/strong> is a more difficult sensation to describe: lightheadedness, a feeling of unsteadiness, or the sense that you might lose consciousness, without necessarily fainting<\/strong>.<\/p>

    Syncope<\/strong> is an actual loss of consciousness, usually brief, followed by a spontaneous return to normal.<\/p>

    Yes. Dizziness can sometimes occur when the amount of blood temporarily reaching the brain decreases<\/strong>.<\/p>

    This can happen when blood pressure drops or when the heart beats too slowly or too quickly<\/strong>, temporarily reducing blood flow to the brain.<\/p>

    However, dizziness has many other causes, and this symptom alone cannot determine its origin.<\/strong><\/p>

    When you stand up, some of the blood temporarily shifts toward the legs because of gravity. The body must quickly adjust to maintain adequate blood pressure and ensure sufficient blood flow to the brain.<\/p>

    If this adjustment occurs too slowly, blood pressure may temporarily drop and cause dizziness<\/strong>. This is known as orthostatic hypotension<\/strong>.<\/p>

    Dehydration and certain medications can make this more likely to occur.<\/p>

    Loss of consciousness occurs when the brain temporarily does not receive enough blood and oxygen<\/strong>. When it is brief and followed by a spontaneous return to normal, it is called syncope<\/strong>.<\/p>

    A loss of consciousness, even if brief, warrants medical evaluation to determine its cause<\/strong>, particularly when it is a first episode.<\/p>

    It is helpful to note the circumstances: what the person was doing just before the episode, whether there were any warning symptoms, and approximately how long it lasted. The account of someone who witnessed the event can also provide valuable information.<\/strong><\/p>

    If the person does not quickly regain consciousness, has been seriously injured in the fall, or is in an unusual state upon awakening, call 911.<\/strong><\/p> <\/div>\n\n <\/div>\n\n <\/div>\n\n <\/div>\n <\/div>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

    The evaluation begins with a detailed description of the circumstances surrounding the loss of consciousness, a physical examination, blood pressure measurement, and an electrocardiogram (ECG)<\/strong>.<\/p>

    Depending on the situation, other tests may be suggested, such as heart rhythm monitoring<\/strong>, an echocardiogram, or a stress test. The choice depends on the circumstances of the episode and what the healthcare professional is looking for.<\/p>

    Not all of these tests are therefore necessary for every person who has experienced syncope.<\/strong><\/p>
