paroxysmal atrial tachycardia paroxysmal supraventricular tachycardia (PSVT) a narrow QRS tachycardia that begins and ends abruptly; it may be terminated with a vagal maneuver. It has two common mechanisms, atrioventricular nodal reentry and circus movement that uses the atrioventricular node anterogradely and an accessory pathway retrogradely.

Facts Deep vein thrombosis (DVT) is a medical condition that occurs when a blood clot forms in a deep vein. These clots usually develop in the lower leg, thigh, or pelvis, but they can also occur in the arm.

Mean platelet volume Mean platelet volume (MPV) is a machine-calculated measurement of the average size of platelets found in blood and is typically included in blood tests as part of the CBC.ince the average platelet size is larger when the body is producing increased numbers of platelets, the MPV test results can be used to make inferences about platelet production in bone marrow or platelet destruction problems.

Partial Thromboplastin Time  [en EspaÃ±ol] Test Overview. Partial thromboplastin time (PTT) is a blood test that measures the time it takes your blood to clot. A PTT test can be used to check for bleeding problems. Blood clotting factors are needed for blood to clot (coagulation).

Medical Definition of Vena cava home / medterms medical dictionary a-z list / vena cava definition Medical Definition of Vena cava Vena cava: The superior vena cava is the large vein which returns blood to the heart from the head, neck and both upper limbs. The inferior vena cava returns blood to the heart from the lower part of the body. The return of blood via the vena cava can be compromised and cause disease. For example, in the superior vena cava syndrome, the symptoms that result from compression of the large vein that carries blood down to the heart.

Overview Deep venous thrombosis (DVT) is the presence of coagulated blood, a thrombus, in one of the deep venous conduits that return blood to the heart. The clinical conundrum is that symptoms (pain and swelling) are often nonspecific or absent.

- Deep Vein Thrombosis (DVT) Quick Overview. The definition of deep venous thrombosis (DVT) is a condition in which a blood clot is embedded in one of the major deep veins of the lower legs, thighs, pelvis, or arm. A clot blocks blood circulation through these veins, which carry blood from the lower body back to the heart.

Tachycardia | Fast Heart Rate Some forms are called paroxysmal atrial tachycardia (PAT) or paroxysmal supraventricular tachycardia (PSVT). Electrical signals in the heart's upper chambers fire abnormally, which interferes with electrical signals coming from the sinoatrial (SA) node --- the heart's natural pacemaker.

What is PSVT? What are its causes, effects? The signal is conducted through the atria (the upper heart chambers) and stimulates the atria to contract. Paroxysmal supraventricular tachycardia (PSVT) can be initiated in the SA node; in the atria or the atrial conduction pathways; or in the AV node. It occurs most often in young people and infants. Risks include smoking, caffeine, alcohol use, and illicit drug use. PSVT can occur with digitalis toxicity.

Thrombosis Medical Definition of Deep vein thrombosis. Deep vein thrombosis: A blood clot within a deep vein, typically in the thigh or leg. The blood clot (thrombus) can break off as an embolus and make its way to the lung, where it can cause lung problems. Abbreviated DVT. Also known as economy-class syndrome.

Supraventricular Tachycardia (SVT, PSVT Symptoms, Causes, and Treatments) Supraventricular Tachycardia (SVT, PSVT) Causes. Paroxysmal (also termed sporadic) supraventricular tachycardia usually occurs without other symptoms. However, it may be associated with a number of medical conditions, such as the following: 1  Hardening of the arteries (atherosclerosis). 2  Heart failure. 3  Thyroid disease. 4  Chronic lung disease. 5  Pneumonia.

- Depending upon the heart rhythm, medications can be injected intravenously to reset the AV node or to decrease heart muscle excitability. Adenosine is a short-acting medication that is commonly used as a first-line drug to treat PSVT.

Deep vein thrombosis What is deep vein thrombosis? Deep vein thrombosis (DVT) is a blood clot (thrombus) in a deep vein, usually in the legs. Clots can form in superficial veins and in deep veins. Blood clots with inflammation in superficial veins (called superficial thrombophlebitis or phlebitis) rarely cause serious problems.

- Abstracted by Gary W. Lemon. Clinical Presentation /Diagnosis. Superficial venous thrombophlebitis (SVT) is an attack of blood clots in veins that lie under the skin within the fat of the body but not in the. It is deep veinsa relatively common medical problem. It can get better and then happen again (recurrence). It has a low chance but known risk of deep vein thrombosis (DVT, blood clots in the deep veins) and pulmonary embolism (blood clots moving to the lungs). How often SVT occurs in the population is unknown.

Supraventricular Tachycardia (SVT, PSVT Symptoms, Causes, and Treatments) When tachycardia occurs, it is usually referred to as paroxysmal supraventricular tachycardia (often abbreviated PSVT). Supraventricular tachycardia also may be chronic (ongoing, long-term). The following is a list of conditions that fit under the broad definition of SVT: Sinus tachycardia.

Supraventricular tachycardia Supraventricular tachycardia. Supraventricular tachycardia (SVT) is an abnormally fast heart rhythm arising from improper electrical activity in the upper part of the heart. There are four main types: atrial fibrillation, paroxysmal supraventricular tachycardia (PSVT), atrial flutter, and Wolff-Parkinson-White syndrome. Symptoms may include palpitations, feeling faint, sweating, shortness of breath, or chest pain.
