What is/are the inferior lead(s)?
Lead 2, 3 and AVF
what is/are the left lateral lead(s)?
lead 1 and lead AVL
what is/are the right lateral lead(s)?
lead AVR
which leads will show you the anterior side of you heart?
V1-6
when is a Q wave considered abnormal?
when it is wide
what is the Q wave?
negative wave, first deflection.
what is a long PR interval indicative of?
AV nodal delay
how do you measure the PR interval?
from beginning of P wave to the beginning of Q wave
what does the PR interval measure?
the wave through the SA node
T/F
ST segments include the T wave
FALSE
when is an ST segment abnormal?
when its elevated or depressed
why do we look at the QT interval?
to make sure its not too long
what type of fibers transmit the depolarization of the SA node into the left atrium (across the atrial septum)?
Bockman's fibers
what is special about the left bundle branch?
it is a hemibundle. It contains two branches an anterior and posterior branch. Only the left is split.
why is the SA node the cardiac pacemaker?
because the intrinsic rate of the SA node if faster than any other pacemaker cell in the heart
what is the pace of the SA node? AV node? Ventricle?
SA: 60-100
AV: 40-60
Ventricle: < or equal to 40
T/F
ALL cardiac tissue can be a pacemaker
True!!

All cardiac tissues have automaticity so if the tissues above it are knocked out for some reason, then the rest of the heart will still contract.
what is the pace of the "normal" junctional rhythm? accelerated JR? Jxnal Tchy?
normal :<60
Accelerated: 60-100
Tachy: >100
what are the atrial rhythms and their paces?
ectopic atrial: 45-55
Accelerated atrial: 55-100
Atrial tachy: 100-250
regular, distinct p waves occurring at a rate of 300 BPM.
atrial flutter
no p waves and irregular QRS over 350 bpm
atrial fibrillation
what are the three things needed for reentry?
1) a circuit
2) unidirectional block
3) appropriate speed
what are the ventricular rhythms and their paces?
idioventricular rhythm: 20-40
AIVR: 40-100
V-tach: 100-250
V-flutter: 250-350
V-fib: >350
in the heart, where is the fastest conduction? slowest?
bundle of HIS; AV cap
what is a 1st degree block?
simply delay- lengthening of the PR interval but the QRS gets through every round. PR interval >.2 seconds
What are the two subtypes of second degree block? how do they differ?
Mobitz type 1 and 2
type1: PR interval gets longer and longer as it progresses until there is no QRS association with the P wave. One beat is dropped, but then it comes back. PR interval changes.
type 2: the PP, PR and RR interval is increased and the node just gives out after a certain number of beats. Usually a fixed ratio like 2:1 or 4:1. PR interval does not change.
what is another name for type 1 second degree heart block?
wenckebach
what is third degree block?
can't get any beats through. All P waves with no QRS. No association between atrium and vetricle. Ventricular rate is usually slower than atrial.
what is AV dissociation?
no association btwn atrium and ventricle. Ventricular rate is usually faster than atrial rate.
