Card Set Information
Lectgure 1 for N176/EKG
How can you tell the kidneys aren't being perfused?
decreased urine output
SV x HR
Normal CO, SV and HR
CO 4-8 L or 4,000-8,000L/min
SV and HR are 60-100
Normal urine output amount
Primary forces of electrical impulses of the heart go.....
right to left and top to bottom
S/S of low CO
prolonged cap refill
SOB....using accessory muscles
What does lead II show?
P wave and QRS complex
What does the PR interval measure?
time from the onset of atrial depolarization to the onset of ventricular depolarization
Normal time of PR Interval
.12-.20 or 3-5 small boxes
What does the P wave represent?
What does the QRS complex represent?
Normal length of QRS complex
0.4-.12 seconds or 1-3 small boxes
What causes a wider QRS complex?
Bundle Branch Block
What does the ST segment represent?
early ventricular repolarization....it is isoelectric and is located on the baseline
What does an elevated and depressed ST segment mean?
elevated = MI
depressed = ischemia or dig toxicity
What does the T wave represent?
ventricular repolarization.....should be larger than the P wave
What do these irregular T waves mean?
Flattened or inverted
Tall or peaked
What does the QT interval represent?
the time between the onset of depolarization and the and of repolarization of the venticles
Total duration of ventricular systole
Normal length of QT interval
.35-.40 seconds or 9-10 small boxes
Horizontal axis measures
time in seconds and distance in mm
Vertical axis measures
voltage in mm
Triplicate method of measurement
can only be used if you have a regular rhythm
How do you measure the ventricle rhythm? and what are you noticing? What makes it significant?
is it regular or irregular?
If there is a difference either way by 3 small boxes, it is a problem
Atrial and ventricular rates should be

How do you calculate Mean Arterial Pressure?
1 systolic + 2 diastolic/3
Drugs for bradycardia
Due to changes in the cardiac conduction system, older adults are at increased risk for
When a dysrhythmia is suspected assess patient for
heart failure (elderly)
cerebral perfusion (LOC)

When you are assessing an older person with dysrhythmias consider the following problems....
When educating the elderly make sure....
you know their level of education
can they hear/see/read
provide instruction in large easy to read print
include the family in teaching
inform of community resources of places to take pulse and bp
If a patient has bradydysrhythmias what do I teach to help avoid these....
avoid stimulating the vagus nerve.....keep carotid pressure low, dont bear down or stimulate the gag reflex
How do you teach patients with premature beats or ectopic rhythms?
drink with moderation
take meds and report AE
What do you teach a patient with ischemic heart disease?
treat angina promptly with nitro
if no relief with nitro call 911
if chest pain is accompanied by sweating, nausea, weakness or palpitations call 911
What do I teach older patients about drug therapy?
teach generic and brand name
teach what each drug does
clear instructions about dosage, schedule and side effects
consider physical limitations of older patients...can they see/read/open container
teach all patients to report dizziness, n/v, sob or chest discomfort....report to Dr.
HR and the heart.....
teach all clients to take their pulse and report a HR over 100 or below 60 or any increase in irregularity
Symptoms of hypokalemia
cardiac irregularity (PVC)
Foods high in K+
Symptoms of hypomagnesia
Foods high in magnesium
green leafy vegetables
What do you teach a patient about a pacemaker?
take pulse for 1 min every day at the same time. Report a pulse lower than the set pacemaker rate
report redness/swelling @ insertion site
keep cell phones 6 in away
avoid strong electromagnetic fields
carry a pacemaker id card
Weird things about a pacemaker.....
anti theft devices in stores may interfere with their function
they can set off metal detectors
if you are close to an electrical or magnetic device and you feel weird...move away and take pulse
Things to know about ICD's (Implantable cardioverter defibrillatoros)
cont. with antidysrhythmia meds
if shocked...site or lie down and call Dr.
avoid electromagnetic fields
cell phones kept 6 inch away
carry ICD ID card
report any fainting or black outs
encourage family to learn cpr
avoid strenuous exercise
