EKG artifact usually caused by patient tremors or shivering.

• somatic tremor

• wandering baseline

• Abrade

• electrical interference

EKG artifact in which the normally flat baseline moves up and down across the tracing.

• somatic tremor

• wandering baseline

• Abrade

• electrical interference

an electrocardiography, to lightly scrub the outer layer of the skin to remove debris that can interfere with electrode contact

• somatic tremor

• wandering baseline

• Abrade

• electrical interference

in electrocardiography, a type of artifact caused by the presence of other appliances or equipment in the area surrounding the EKG machine.

• somatic tremor

• somatic tremor

• Abrade

• electrical interference

EKG artifact that occurs when the signal is compromised by frayed or faulty lead wires.

• broken recording

• somatic tremor

• Dextrocardia

• Abrade

a rare heart condition that causes the heart to develop pointing to the right side of the chest instead of the left side.

• Abrade

• broken recording

• Dextrocardia

• wandering baseline

the pathway of electrical impulses that controls the heart’s pumping action.

• intrinsic rate

• Pacemaker

• cardiac conduction system

• bundle of His

the normal firing rate (expressed in beats per minute) associated with a part of the heart’s electrical conduction system.

• sinoatrial node

• intrinsic rate

• Pacemaker

• intrinsic rate

something that regulates the heart’s contractions; natural pacemakers are part of the cardiac conduction system, with the sinoatrial (SA) node acting as the primary pacemaker when the heart is functioning normally. An artificial pacemaker is a battery-powered device that creates electrical impulses to stimulate the heart.

• sinoatrial node

• Pacemaker

• intrinsic rate

• cardiac conduction system

part of the electrical conduction system of the heart, located in the upper part of the right atrium and acting as the primary pacemaker of the heart, with an intrinsic rate of 60–100 BPM; also called the SA node or sinus node.
