Liebermeister's rule - Wikipedia
The relationship between body temperature, heart rate and respiratory rate whether any tachycardia or tachypnoea is caused solely by fever. The relationship between body temperature, heart rate and respiratory rate in acute patients at admission to a medical care unit. Maria M. Liebermeister's rule concerns the increment ratio between an adult individual's cardiac frequency and temperature when in fever. Each Celsius grade of body.
During the physical examination, your doctor will check your heart rate and rhythm. Your doctor also will check for an enlarged heart, for heart murmurs one sign of a heart valve problemfor abnormal lung sounds and for physical signs of thyroid abnormalities enlarged thyroid gland, hand tremor and an abnormal protrusion of the eyes. To further evaluate your tachycardia, your doctor will order an electrocardiogram EKG.
However, because some forms of tachycardia come and go, a one-time office EKG may be normal. If this is the case, you may need a test called ambulatory electrocardiography. For this test, you will wear a portable EKG machine called a Holter monitor for a period, usually for 24 hours. If symptoms occur infrequently, you may have to wear a monitor for much longer.
You will be taught to press a button to record EKG readings when symptoms occur. Depending on the results of your physical examination, other tests may be necessary, such as blood tests to measure your red blood cell count and levels of thyroid hormones and an echocardiogram to see if there are any structural abnormalities of your heart. Sometimes, physicians do "electrophysiology testing," in which they insert special catheters within the heart to collect information on the patterns of the heart's electrical activities.
Expected Duration How long tachycardia lasts depends on its cause. For example, tachycardia resulting from fever will go away when body temperature returns to normal.
Tachycardia resulting from hyperthyroidism or an adrenal gland tumor will go away when the disorder is treated. Tachycardia caused by medications or diet will go away quickly, usually within hours, when the chemical that is causing the problem is used up by the body or excreted in the urine.
Tachycardia caused by cardiac problems can last a long time. Prevention Since tachycardia is usually a sign of some underlying medical problem, discovering and treating the cause is the best way to prevent recurrent tachycardia. The first episode of an arrhythmia that causes a rapid heart beat usually cannot be prevented.

Treatment The treatment of tachycardia depends on its cause. Fever-related tachycardia can be treated with fever-reducing medications, such as acetaminophen Tylenol or ibuprofen AdvilMotrin and others.
If the fever is caused by a bacterial infection, antibiotics also may be needed. To treat blood loss, the patient first is stabilized with fluids given intravenously into a vein or blood transfusions. Then, the source of the bleeding is found and stitched, or corrected with surgery.
Hyperthyroidism can be treated with antithyroid medications such as methimazole Tapazolegeneric versions. Alternative treatments include radioactive iodine, which destroys the thyroid with radiation, or removing most of the thyroid gland with a surgical procedure called subtotal thyroidectomy.
In atrial flutter, the heart's atria beat very fast but at a regular rate. The fast rate results in weak contractions of the atria.
Atrial flutter is caused by irregular circuitry within the atria. Episodes of atrial flutter may resolve themselves or may require treatment.
People who experience atrial flutter also often experience atrial fibrillation at other times. Supraventricular tachycardia is an abnormally fast heartbeat that originates somewhere above the ventricles. It's caused by abnormal circuitry in the heart that is usually present at birth and creates a loop of overlapping signals.
Ventricular tachycardia is a rapid heart rate that originates with abnormal electrical signals in the lower chambers of the heart ventricles. The rapid heart rate doesn't allow the ventricles to fill and contract efficiently to pump enough blood to the body.
Ventricular tachycardia episodes may be brief and last only a couple of seconds without causing harm. But episodes lasting more than a few seconds can become a life-threatening medical emergency. Ventricular fibrillation occurs when rapid, chaotic electrical impulses cause the ventricles to quiver ineffectively instead of pumping necessary blood to the body.
This can be fatal if the heart isn't restored to a normal rhythm within minutes with an electric shock to the heart defibrillation. Ventricular fibrillation may occur during or after a heart attack. Most people who experience ventricular fibrillation have an underlying heart disease or have experienced serious trauma, such as being struck by lightning. Symptoms When your heart is beating too fast, it may not pump blood effectively to the rest of your body.
This can deprive your organs and tissues of oxygen and can cause the following tachycardia-related signs and symptoms: Shortness of breath Lightheadedness Rapid pulse rate Heart palpitations — a racing, uncomfortable or irregular heartbeat or a sensation of "flopping" in the chest Chest pain Fainting syncope Some people with tachycardia have no symptoms, and the condition is only discovered during a physical examination or with a heart-monitoring test called an electrocardiogram.
When to see a doctor A number of conditions can cause a rapid heart rate and tachycardia symptoms.

- Fever - children
It's important to get a prompt, accurate diagnosis and appropriate care. See your doctor if you or your child experiences any tachycardia symptoms. If you faint, have difficulty breathing or have chest pain lasting more than a few minutes, get emergency care, or call or your local emergency number.
Seek emergency care for anyone experiencing these symptoms. Request an Appointment at Mayo Clinic Causes Tachycardia is caused by something that disrupts the normal electrical impulses that control the rate of your heart's pumping action.
