SHARP ECG TEST
tachycardia and bradycardia -(correct answer)>100 bpm <60 bpm Bigeminy -(correct
answer)every other complex is a PVC Trigeminy -(correct answer)pattern in which every third
complex is a premature beat Premature Junctional Contraction (PJC) -(correct answer)Rate:
Normal or accelerated P wave: inverted or absent QRS: normal Conduction: normal rhythm:
irregular: PICs occur early in cycle of baseline rhythm -an ectopic pacemaker in the AV
Junction produces PJC's -may occur in heatlhy or diseased hearts -if occasional, insignificant
Premature Atrial Contraction (PAC) -(correct answer)Heart Rate: Depends on underlying
rhythm Regularity: Interrupts the regularity of underlying rhythm P-Wave: can be flattened,
notched, or unusual. May be hidden within the T wave PRI: measures between .12-.20
seconds and can be prolonged; can be different from other complexes QRS: <.12 seconds
Characteristics of Ventricular Tachycardia -(correct answer)Wide an bizarre QRS complex,
greater than 100 beats per minute, absent P waves, no PRI, can be monomorphic or
polymorphic SA node rate -(correct answer)60-100 bpm AV node rate -(correct answer)40-60
bpm Prukinje fiber rate -(correct answer)15-40bpm Accelerated Junctional Rhythm -(correct
answer)regular rhythm, rate 60-100, p waves inverted or occur before during or after QRS, PRI
measured if p before QRS <0.12 AV Blocks -(correct answer)AV blocks are identified as a
delay or interruption of the electrical impulse conduction beyond the AV node. It is evaluated
by measuring the PR interval in ECG traces. THE PR INTERVAL IS THE KEY OF
DIFFERENTIATION AND CLASSIFICATION OF THE AV BLOCKS! First degree AV block
-(correct answer)prolonged PR interval Second Degree AV block type 1 -(correct answer)AKA
Wenckebach Results from a cyclical and progressive conduction delay through the AV junction.
Characteristic cyclical lengthening of the PR interval followed by a dropped QRS (or a P wave
with no QRS). Irregular Rhythm Second Degree AV Block Type 2 -(correct answer)intermittent
interruptions of AV conduction; *QRS's just drop off with no warning* Third degree AV block
(complete heart block) -(correct answer)Atrial and ventricular rhythms regular Ventricular rate
is 40-60 bpm (AV node origin); < 40 bpm (Purkinje system origin) No relationship between P
waves and QRS complexes QRS complex normal (originating in AV node) or wide and bizarre
(originating in Purkinje system) Ventricular tachycardia (V-tach) -(correct answer)A condition in
which the heartbeat is quite rapid; if rapid enough, ventricular tachycardia will not allow the
heart's chambers to fill with enough blood between beats to produce blood flow sufficient to
meet the body's needs. Ventricular fibrillation (V-fib) -(correct answer)abnormal heart rhythm
which results in quivering of ventricles atrial fibrillation -(correct answer)occurs when the
normal rhythmic contractions of the atria are replaced by rapid irregular twitching of the
muscular heart wall Atrial Flutter -(correct answer)irregular beating of the atria; often described
as "a-flutter with 2 to 1 block or 3 to 1 block" Asystole -(correct answer)absence of contractions
of the heart heart layers -(correct answer)Endocardium ( inner), myocardium ( middle), and
epicardium ( outer) treatment for a fib -(correct answer)heparin & diltiazem (cardizem)
Treatment for atrial flutter -(correct answer)Medication and/or electrical cardioversion
