Basics of the Heart
How many chambers does the heart have?
4.
What is the normal heart rate range?
60–100 bpm.
What rhythm has regular, even spacing between QRS complexes and normal P waves?
NSR.
What can cause sinus tachycardia?
Exercise or stress.
A patient complains of sudden palpitations and dizziness. The ECG shows a heart rate of 180 bpm with narrow QRS complexes.
SVT.
What is the upper chamber of the heart called?
Atrium.
A slow heart rate under 60 bpm is called what?
Bradycardia.
What rhythm is a flat line on the ECG?
Asystole.
What is the diagnosis of the ECG STEMI
Heart attack.
An unconscious patient is found with no pulse. The ECG shows a flat line. CPR is started immediately.
Asystole.
What does ECG stand for?
Electrocardiogram.
A fast heart rate over 100 bpm is called what?
Tachycardia.
What rhythm has wide, bizarre QRS complexes with no P waves?(Also known of attack of the V's)
Ventricular tachycardia.
What is the first thing to do for asystole?
Check patient and start CPR
A patient experiences chest pain and collapses. The monitor shows a rapid, irregular, and chaotic rhythm with no identifiable P waves.
V-fib.
Which part of the heart is known as the pacemaker?
SA Node.
What rhythm is considered normal for a healthy person?
Normal Sinus Rhythm(NSR).
What rhythm is a chaotic, wavy line with no organized QRS or P waves?
Ventricular-Fibrillation
What device delivers an electrical shock to reset the heart rhythm?
Defibrillator (AED)
A monitor shows ST-SEGMENT ELEVATIONS on the ECG while P waves and QRS complexes remain present, but the rhythm is otherwise regular.(also known as a heart-attack)
ST-Elevation Myocardial Infarction(STEMI).
What does the P wave on an ECG represent?
Atrial depolarization.
What rhythm has no identifiable P waves and irregular QRS spacing?
Atrial fibrillation.
What rhythm shows a sawtooth pattern?
Atrial flutter.
What medication is commonly used for bradycardia?
Atropine.
A patient reports palpitations and shortness of breath. The ECG shows sawtooth waves with a rapid, regular ventricular response.
A-flutter.
