Sinus tachycardia Health Dictionary

Abnormally fast heartbeat.... tachycardia

A term applied to narrow cavities of various kinds, occurring naturally in the body, or resulting from disease. Thus it is applied to the air-containing cavities which are found in the frontal, ethmoidal, sphenoidal and maxillary bones of the SKULL, and which communicate with the NOSE. The function of these paranasal sinuses, as they are known, is doubtful, but they do lighten the skull and add resonance to the voice. They enlarge considerably around puberty and in this way are a factor in the alteration of the size and shape of the face. The term is also used in connection with the wide spaces through which the blood circulates in the membranes (MENINGES) of the BRAIN. Cavities which are produced when an ABSCESS has burst, but remain unhealed, are also known as sinuses (see also FISTULA).... sinus

An unusually fast but regular beating of the HEART occurring for periods that may last several hours or days. In most people with this abnormality the heart rate is between 140 and 180 beats a minute; rarely, the rate may rise as high as 250–300 beats. The condition occurs when abnormal electrical impulses that arise in the upper chambers (atria) of the heart override the normal control centre – the sinoatrial node – for the heartbeat. Symptoms usually include breathlessness, palpitations, pain in the chest and fainting. An ELECTROCARDIOGRAM (ECG) is taken to help make the diagnosis. An acute episode can sometimes be stopped by VALSAVA’S MANOEUVRE or by drinking cold water. Anti-arrhythmic drugs (see ARRHYTHMIA) such as adenosine and digoxin are used to treat recurrent attacks. Occasionally, a severe attack may need to be treated with an electric shock to the heart: this is known as DEFIBRILLATION.... supraventricular tachycardia

A channel for venous blood placed either side of the sphenoid bone at the base of the SKULL behind the eye sockets. Blood drains into it from the eye, the nose, the brain and part of the cheek, and leaves via the internal jugular and facial veins. Sometimes the sinus becomes blocked by a blood clot (thrombus), usually a complication of a nearby bacterial infection. A potentially serious condition, it should be treated with thrombolysis and antibiotics.... cavernous sinus

One of the airspaces that form the paranasal sinuses (see SINUS) within some of the frontal bones of the skull. These sinuses are lined with mucous membrane and open into the nasal cavity.... frontal sinus

Thrombosis arising in the cavernous sinus of the sphenoid bone in the head.

Cause: Septicaemia or infected embolism conveyed from elsewhere – veins of the face, sinuses, head. May be a complication of meningitis.

Symptoms: headache, nausea, swelling of eyelids and forehead, pupils distended, veins of temples prominent, fever with severe constitutional disturbance.

Prognosis: usually fatal in the absence of orthodox antibiotics, but anti-staphylococcal herbs are helpful. Tinctures. Formula. Echinacea 3; Goldenseal 2; Myrrh (Tincture) 1. 1 teaspoon in water every 2 hours (acute). Thrice daily (chronic).

Treatment by or in liaison with general medical practitioner. ... cavernous sinus thrombosis

A serious cardiac arrhythmia in which each heartbeat is initiated from electrical activity in the ventricles rather than from the sinoatrial node in the right atrium.

It is caused by an abnormally fast heart-rate due to serious heart disease, such as myocardial infarction or cardiomyopathy.

It may last for a few seconds or for several days.

Diagnosis is confirmed by ECG.

Emergency treatment is with defibrillation and an antiarrhythmic drug.... ventricular tachycardia

Sited within some of the bones of the SKULL, these are spaces ?lled with air and lined by MUCOUS MEMBRANE. The sinuses comprise frontal and maxillary (a pair of each), ethmoidal (a group of small spaces), and two sphenoid sinuses. They drain into the nasal cavities (see NOSE). When a person has an upper respiratory infection, the sinuses sometimes become infected: this causes pain, purulent discharge from the nose and obstruction of the nasal passages (see SINUSITIS). Generally all that is required is a decongestant and antibiotic but, occasionally, infection may spread to produce a cerebral abscess or cerebral venous sinus thrombosis (see BRAIN, DISEASES OF).... paranasal sinus

A SINUS that contains hairs, usually occurring in the cleft between the buttocks. It may get infected and cause considerable pain. Treatment is by antibiotics and, if necessary, surgical removal.... pilonoidal sinus

Abnormal function of the heart’s sinoatrial node that leads to episodes of bradycardia (slow heart-rate), alternating bradycardia and tachycardia (fast heart-rate), or very short episodes of cardiac arrest.

The cause is usually coronary artery disease, but may be a cardiomyopathy.

Symptoms may include lightheadedness, fainting, and palpitations.

The diagnosis is confirmed by a 24-hour ECG recording.

Treatment is usually by antiarrhythmic drugs and the fitting of an artificial pacemaker.... sick sinus syndrome

A slow, but regular heart-rate (less than 60 beats per minute) caused by reduced electrical activity in the sinoatrial node. Sinus bradycardia is normal in athletes, but in others it may be caused by hypothyroidism, a myocardial infarction, or by drugs such as beta-blockers or digoxin.... sinus bradycardia

Any of the air-filled cavities in the bones surrounding the nose. These include 2 frontal sinuses in the

lower forehead; 2 ethmoidal sinuses between the eyes; 2 maxillary sinuses in the cheekbones; and the sphenoidal sinuses in the skull behind the nose. Mucus drains from each sinus along a channel that opens into the nose. Infection of a sinus causes sinusitis.... sinus, facial

(AVRT) *re-entry tachycardia arising from the presence of an abnormal electrical connection between atria and ventricles situated outside the *atrioventricular node. See accessory pathway.... atrioventricular reciprocating tachycardia

a pocket in the wall of the carotid artery, at its division in the neck, containing receptors that monitor blood pressure (see baroreceptor). When blood pressure is raised, impulses travel from the receptors to the vasomotor centre in the brain, which initiates a reflex *vasodilatation and slowing of heart rate to lower the blood pressure to normal.... carotid sinus

the presence of thrombosis in the dural venous sinuses, which drain blood from the brain. Symptoms may include headache, abnormal vision, any of the symptoms of stroke (such as weakness of the face and limbs on one side of the body), and seizures. Treatment is with anticoagulants.... cerebral venous sinus thrombosis

a rare tumour of fetal remnants of the ovaries or testes. In women it is an aggressive malignant ovarian tumour that develops in adolescence and may secrete alpha-fetoprotein and human chorionic gonadotrophin, which can be used as *tumour markers. It is treated by oophorectomy with adjuvant chemotherapy.... endodermal sinus tumour

(ESS) surgery of the *paranasal sinuses using endoscopes. Functional endoscopic sinus surgery (FESS) clears inflamed tissue from routes of sinus drainage and aeration to allow the other sinuses to return to normal.... endoscopic sinus surgery

(FESS) see endoscopic sinus surgery.... functional endoscopic sinus surgery

(maxillary antrum) see paranasal sinuses.... maxillary sinus

a normal variation in the heart rate, which accelerates slightly on inspiration and slows on expiration. It is common in young fit individuals.... sinus arrhythmia

a normal heart rhythm, usually as recorded on an electrocardiogram. The *sinoatrial node, located in the right atrium, normally functions as the natural pacemaker for the heart.... sinus rhythm

a rapid heart rate due to a self-sustaining circulation of electrical impulses from the atria to the ventricles and back again. This re-entry circuit requires the presence of an abnormal second electrical conduction pathway in addition to the usual atrioventricular nodal connection route. The abnormal pathway may be located within the *atrioventricular node (causing *atrioventricular nodal re-entry tachycardia) or it may be an *accessory pathway situated outside the atrioventricular node (causing *atrioventricular reciprocating tachycardia). Medication is often effective and *radiofrequency ablation is usually curative.... re-entry tachycardia
