Pathophysiology/Disorders of Cardiac Conduction

by scott
Across
Rapid heart rate, origin in SA node.
Type 1 or 2 name in second degree block.
Involves direct application of cold probe to arrhythmogenic cardiac tissue. name of procedure.
Slow heart rate.
Brief QT syndrome; QT interval less than 320 milliseconds. ___________ QT syndrome.
Therapy used for treating life threatening superventricular tachyarrhythmias; catheter or surgical technique.
Rapid disorganized atrial activation with uncoordinated contraction. Risk increases with age.
Name or stage of degree block; lengthening of P-R interval.
Class 11 cardiac drug; commonly used beta adrenergic blocker, blunts sympathetic nervous syste.
Period of time during which polarity of membrane potential is reversed.
Class 1 cardiac drug, blocks fast sodium channels; topical anesthetic congener.
Name or stage of degree block, atria and ventricles show own rates of impulse.
Monitoring system used for long term monitoring, person wears device.
In V-tach, QRS complexes can be uniform in shape. Name to describe shape.
Name of innervation system throughout heart.
Type of superventricular tachycardia; tachyarrhythmias originate above the Bundle of His bifurcation, sudden onset.
This fraction refers to the amount or percentage of blood pumped out of ventricles with each contraction.
Down
Class 111 cardiac drug. Serious side effects, like LQTS.
Type of attack, seen in complete heart block, decreased cardiac output, possible syncope. Two names together.
Sinus ________; Failure of SA node to discharge, irregular pulse.
Goal of therapy is to provide an electrical pulse to heart for depolarizing the heart during passage of current.
Type of arrhythmia; AV node acts as pacemaker should SA node fail or become irregular.
Type of pause (physiological) that occurs while a ventricle waits to reestablish its previous rhythm.
Rapid atrial ectopic tachycardia; 250-450bpm.
These drugs have these effects, strengthen force of muscular contraction. Use adjective form.
Type of atrial ta chycardia; firing of several ectopic foci in atrium; three distinct p wave morphologies.
Contractions that originate in atrial conduction pathways or atrial muscle; occur before next expected SA node impulse. abbreviation.
If standard monitor system fails to diagnose, this recorder can be implanted.
Caused by ventricular ectopic pacemaker; single, doubles or triples.
Sick ____________ rhythm. Results from damage of SA node; syncope may result.
Regular beating of heart.
Prolongation of QT interval that can result in in V-tach called torsade de pointe. abbreviation.
Sinus ___________ block; Sinus node fails to depolarize the atria.
