Phlebotomy is the act of drawing or removing blood from the circulatory system through a cut (incision) or puncture in order to obtain a sample for analysis and diagnosis. Phlebotomy is also done as part of the patient’s treatment for certain blood disorders. Phlebotomy that is part of treatment (therapeutic phlebotomy) is performed to treat […]

Phlebography is an x ray test that provides an image of the leg veins after a contrast dye is injected into a vein in the patient's foot. Phlebography is primarily performed to diagnose deep vein thrombosis—a condition in which clots form in the veins of the leg. Pulmonary embolism can occur when those clots break […]

Pericardiocentesis : A procedure performed with a needle to remove fluid for diagnostic or therapeutic purposes from the tissue covering the heart (pericardial sac). The heart is surrounded by a membrane covering called the pericardial sac. The sac consists of two layers, the parietal (outer) and visceral (inner) layer, and normally contains a small amount […]

Pacemakers – Definition A pacemaker is a surgically implanted electronic device that regulates a cardiac arrhythmia. Pacemakers are most frequently prescribed when the heartbeat decreases under 60 beats per minute at rest (severe symptomatic bradycardia). They are also used in some cases to slow a fast heart rate over 120 beats per minute at rest […]

Lipid tests Definition Lipid tests are routinely performed on plasma, which is the liquid part of blood without the blood cells. Lipids themselves are a group of organic compounds that are greasy and cannot be dissolved in water, although they can be dissolved in alcohol. Lipid tests include measurements of total cholesterol, triglycerides, high-density lipoprotein […]

Operation ICD insertion is considered minor surgery, and can be performed in either an operating room or an electrophysiology laboratory. The insertion site in the chest will be cleaned, shaved, and numbed with local anesthetic. Generally, left-handed persons have ICDs implanted on the right side, and visa versa, to speed return to normal activities. Two […]

Implantable cardioverter defibrillator Definition The implantable cardioverter-defibrillator (ICD) is a surgically implanted electronic device that directs an electric charge directly into the heart to treat life-threatening arrhythmias. Purpose The implantable cardioverter-defibrillator is used to detect and stop life-threatening arrhythmias and restore a productive heartbeat that is able to provide adequate cardiac output to sustain life. […]

Major Antihypertensive Classes ACE Inhibitors Angiotensin-converting enzyme (ACE) inhibitors block the conversion of angiotensin I to angiotensin II, resulting in decreased aldosterone production with subsequent increased sodium and water excretion. Renin and potassium levels are usually increased as a result of this medication. The hemodynamic response includes decreased peripheral resistance, increased renal blood flow, and […]

The goal of therapy is not just to bring the blood pressure lower than 140 mm Hg systolic and 90 mm Hg diastolic, but rather to prevent the morbidity and mortality associated with hypertension. As such, the decision to treat hypertension is based on documentation that the blood pressure has remained elevated and on assessment […]

The heart-lung machine is medical equipment that provides cardiopulmonary bypass, or mechanical circulatory support of the heart and lungs. The machine may consist of venous and arterial cannula (tubes), polyvinyl chloride (PVC) or silicone tubing, reservoir (to hold blood), bubbler or membrane oxygenator, cardiotomy (filtered reservoir), heat exchanger(s), arterial line filter, pump(s), flow meter, inline […]
