Pacemakers

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 (tachycardia). …

Pericardiocentesis

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 of …

Phlebography Venography

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 off …

Phlebotomy
