procedure in which a catheter is inserted through a vein in the groin and threaded to the heart to correct electrical problems in the heart that cause an arrhythmia
Supraventricular Tachycardia (SVT)
Episodes of abnormally fast/racing heartbeat
inability of the aortic valve to perform at the proper levels, which results in blood flowing back into the left ventricle from the aorta
irregular beating of the atria
Rapid heartbeat originating from the atria
A dysfunction of the nerves that regulate nonvoluntary body functions, such as heart rate, blood pressure, and sweating.
Postural hypotension (orthostatic hypotension)
drop in blood pressure related to change in position (supine/seated to standing), caused by pooling of blood in the veins, decrease in venous return, and decreased cardiac output
decrease heart rate and dilate arteries by blocking beta receptors
Long QT syndrome
A condition characterized by a QT interval exceeding approximately 450 ms.
Autosomal dominant heart rhythm disorder most common in Asian males. ECG pattern of pseudo-right bundle branch block and ST elevations in V1-V3.
bundle branch block (BBB)
Occurs when the electrical impulse is blocked from traveling down the bundle of His or bundle branches. Results in the ventricles beating at a different rate than the atria. Also called a heart block.
a temporary abnormal heartbeat (not a sustained abnormal rhythm) that can be read on an EKG or perceived by the patient as a palpitation
effort at breathing when physically active
any sound produced as the heart functions normally
(inflammation of blood vessels, hence the strawberry tongue) causes coronary artery aneurysms.
Tick-borne disease caused by the spirochete Borrelia burgdorferi.
many different types; symptoms from muscle weakness to poor growth, seizures, organ failure
A device that delivers electrical impulses to the heart to regulate the heartbeat
pounding, racing heartbeats
premature ventricular contractions (PVCs)
extra, abnormal heartbeats that disrupt the regular ventricular rhythm of the heart
"Passing out", loss of consciousness or fainting
Accessory conduction pathway that bypasses the AV node; Delta wave may lead to SVT.
electrocardiography, measures heart rhythm
ultrasound of the heart, looks at the heart structure
normal sinus rhythm, NSR, normal ECG
documentation for a normal ECG
structurally normal heart, good biventricular function
documentation for a normal echocardiogram
