A condition that stops the conduction of electrical impulses through the heart. May be caused by damage to cardiac tissue or by the disease process within the electrical impulse system. Condition may be intermittent or permanent.
: First-Degree Heart Block - Delay in the conduction of an atrial impulse to the ventricle through the AV-node characterized by a prolonged P-R interval on an ECG.
: Second-Degree Block - Intermittent blockage of atrial impulses at the A-V node. Conduction ratios are represented by the number of P-waves versus the number of ventricular responses in an ECG. Mobitz I is a type of second-degree heart block, also known as the Wenckebach phenomenon, in which the time between the atrial and ventricular contractions (P-R interval) becomes progressively longer until a P-wave is not conducted through the A-V node. Mobitz II is a type of second-degree heart block in which the time between the atrial and ventricular contractions is a consistent P-R interval, but an occasional P-wave is not conducted through the A-V node.
: Complete Heart Block - A pathologic condition in which intrinsic conduction is blocked at any level in the A-V junction. Also referred to as third-degree heart block.
Industry:Medical devices
Another term for a heartbeat. The number of times the heart beats (completes a cardiac cycle of contraction and relaxation) in a minute. A normal heart rate typically ranges from 60 to 100 beats per minute at rest.

Necrosis or tissue death, usually due to inadequate or absent blood supply.
Industry:Medical devices
A procedure where portions of artery or vein from one area of the patient's body are used to reroute blood around a blockage in another area.
Industry:Medical devices

Industry:Medical devices
High blood pressure usually ranging from 140/90 mm Hg to 200/110 mm Hg.
Industry:Medical devices
A disorder of the heart muscle caused by an enlarged heart resulting from the increase in the size of muscle tissue. In some people the disease is transmitted genetically and its cause is unknown.
