Current Medical Diagnosis And Treatment 2023, 62ndEdition TEST BANK By Maxine Papadakis, Stephen
Mcphee
Cardiac rhythms may be classified as: - ANSWER:Regular or irregular
When rhythms are irregular, or rates are either fast or slow, and ECG will identify the
origin of the beats to be what? - ANSWER:Sinus node, AV node, Atrium, or Ventricle
and the conduction pattern
Normal range for sinus rhythm - ANSWER:60-100 bpm
If the rhythm is regular, - ANSWER:Look at the rate
(>100 Fast, 60-90 Normal, or <60 Slow)
if rhythm is irregular - ANSWER:note the pattern of irregularity
(sporadic, regularly irregular, or irregularly irregular)
Fast >100 rates - ANSWER:Sinus Tachycardia
Supraventricular (atrial or nodal) Tachycardia
Atrial Flutter with a regular ventricular response
Ventricular Tachycardia
Normal 60-90 rates - ANSWER:Normal sinus rhythm
Second degree AV block
Atrial Flutter with a regular ventricular response
Slow <60 rates - ANSWER:Sinus Bradycardia
Second-Degree AV block
Complete Heart Block
100-180 bpm - ANSWER:sinus tachycardia
150-250 bpm - ANSWER:supraventricular (atrial or nodal) tachycardia
100-175 bpm - ANSWER:Atrial Flutter with a regular ventricular response (fast)
60-90 bpm - ANSWER:normal sinus rhythm (heart rate)
60-100 bpm - ANSWER:Second- degree AV Block (normal)
75-100 bpm - ANSWER:Atrial Flutter with a regular ventricular response (normal)
<60 bpm - ANSWER:sinus bradycardia
, 30-60 bpm - ANSWER:second-degree AV block (slow)
<40 bpm - ANSWER:Complete heart block
Premature or extra beats at random intervals, but normal underlying rhythm (e.g.,
atrial or ventricular premature contractions, sinus arrhythmia) - ANSWER:Sporadic
Regular pattern of cadences (ventricular trigeminy) - ANSWER:Regularly Irregular
No discernable regularity (atrial fibrillation, atrial flutter) - ANSWER:Irregularly
Irregular
Rhythm varies cyclically, speeding up with inspiration and slowing down with
expiration.
Heart sounds are normal, though S1 may vary with the heart rate. -
ANSWER:Sporadic Sinus Arrhythmia
Atrial or nodal beat comes earlier than expected followed by a pause, and then
rhythm resumes.
Heart sounds: S1 may differ in intensity from the S1 of normal beats and S2 may be
decreased - ANSWER:Atrial or nodal Premature contractions
(supraventricular)
Beat of ventricular origin comes early the expected, followed by a pause and the
rhythm resumes.
Heart sounds: S1 may differ in intensity from normal S1, and S2 may be decreased.
Both are likely to be split. - ANSWER:Sporadic Ventricular Premature Contractions
(ventricular bigeminy or trigeminy
Ventricular rhythm is totally irregular, with short runs of the irregular ventricular
rhythm seeming regular.
Heart sounds: S1 varies in intensity - ANSWER:Irregularly Irregular Atrial Fibrillation
and Atrial Flutter with Varying AV Block
Normal pulse pressure - ANSWER:30-40 mmHg, pulse contour is smooth and
rounded (notch on descending slope not palapable)
Small, weak pulse - ANSWER:- diminished pulse pressure
- weak and small on palpation
- slow upstroke
- prolonged systolic peak
Small, weak pulse causes - ANSWER:- decreased Stroke volume
- Heart failure
- Hypovolemia
- Severe aortic stenosis
